Rifle Barrels::Chambers

Drawing upon 35 years of close involvement in the demanding sport of bench rest competition, we possess a unique understanding of the importance of a carefully aligned, precise chamber. Our chambers are painstakingly cut to a singular standard of machining excellence, because without an absolutely true chamber, no rifle will shoot to its full potential. Dimensional accuracy is also critical in every other step in the barrel-fitting process. Everything must be just right.
We are chambering and fitting Shilen barrels for the following cartridges. Please note that the dimensions in parentheses indicate special neck diameters. These are either "tight necks", which require turning case necks, or "minimum necks", which may or may not require neck-turning. If you have questions, please contact us for recommendations.

Rifle Barrels::prethreaded and Chambered Barrels

These barrels, supplied already threaded, chambered, crowned and polished by Shilen, are available in all Shilen contours and chamberings. To complete a beautifully precise fitting job, the gunsmith must add just a few finishing touches.
In the machining processes, Shilen nearly-completed barrels are given the same care and dedication as our custom barrel installations. They must meet Shilen standards of chamber and barrel thread alignment, which are vital to fine accuracy. Crowns are cut with equal care and precision.
All barrels are rifled to criteria weve developed in years of involvement in benchrest competition, and are, of course, warranted against defects in materials and workmanship. The bores of every one of these barrels must air gauge to the uncompromising dimensions listed in the Shilen Rifle Barrels data sheet.
Each barrel exterior is polished to a 180-grit finish. The bores of stainless steel barrels are supplied hand lapped, and chrome-moly can also be hand lapped for an additional charge. Barrels are crowned at standard length as specified in our barrel chart--unless you request otherwise. (See Shilen Rifle Barrels data sheet.) All chambers come already polished.

To complete the job, the gunsmith need only accomplish these steps:

1. Check for correct thread mating of barrel to receiver. Barrel thread is standard size, but variations in action threads
could mean an overly tight or loose fit.

2. Cut shoulder for the correct headspace. The chamber is cut .010" to .015" deeper than standard dimensions to allow for this.

3. Outside finish the barrel, if required.


Available in threading for:

• Remington Model 700, 600, XP-100, 40-X Rimfire
• Sako 1960 L Series, 1980 A Series, 1990 M Series
• Weatherby Mark V
• Winchester Model 70, Post 64 only
• Ruger Model 77 • Mauser 98
• Browning A-bolt
• Anschutz Model 2007/ 2013


Ordering:
For each barrel, please specify the following, or use the Shilen Prethreaded and Chambered Barrel Order Form.

1. Barrel Grade
2. Stainless Steel or Chrome-moly
3. Cartridge/Caliber (see Shilen Cartridge Chamberings data sheet)
4. Twist
5. Contour #
6. Length if other than standard (see Shilen Rifle Barrels data sheet)
7. Action Make (see list above)
8. Hand lap chrome-moly? (Match Grade only)

Because these are special-order barrels, we must require prepayment. Sorry, no C.O.D.s. Delivery in 4 to 6 weeks. Please see our Price List for current prices.

Rifle Barrels::Ruger Barrels



Do you want to wring the very finest accuracy from your Ruger 10/22 semi-auto or bolt action 77/22?

Well, here are the barrels that are up to the job! Each one of these Shilen target barrels must meet our Match Grade criteria, air gauging within 0.0005" of a special undersized groove diameter designed to produce optimum accuracy from all types of .22 ammunition. The bore also must not vary in diameter more than 0.0003" for its entire length. These are serious barrels for serious shooters.
In addition, the barrels are stress relieved and warranted by Shilen against defects in materials and workmanship. Offered in both Chrome-moly and Stainless Steel, they are completely finished by Shilen and are ready for installation. Chrome-moly barrels are supplied blued. Stainless steel barrels come in polished white, with a hand-lapped bore. As further proof that these are serious match barrels, note the following specifications:


10/22 Barrels
Barrel grade: Match Grade Only Material: Chrome-moly or Stainless Steel Length: 18" Groove diameter: .2215" Twist: 16" Outside diameter: .920" straight--no taper Chamber: Shilen/Bentz, designed for optimum accuracy in semi-autos Crown: Target


77/22 Barrels
Barrel grade: Match Grade Only Material: Chrome-moly or Stainless Steel Length: 22" Groove diameter: .2215" Twist: 16" Outside diameter: .920" to .700" straight taper Chamber: Tight match, designed to land-engrave bulletsCrown: Target


Barrels are normally in stock for immediate shipment. In ordering, please specify barrel material and Ruger model. Prices are F.O.B. Ennis, Texas, and subject to change without notice. Please see our price list.

Pistol Barrels


Shilen pistol barrels are rifled with the same care an precision as Shilen rifle barrels, which are perhaps the winningest barrels in benchrest competition. You simply cannot buy a finer pistol barrel than Shilen.These barrels are divided into two categories. Standard barrels are offered in calibers and twists for popular target, hunting and plinking calibers. Silhouette barrels, especially for the demanding sport of metallic pistol silhouette, are available in every rifle barrel caliber and twist offered by Shilen. Please see the Contours and Twists Data Sheet. Regardless of category, every barrel is button rifled with 8 lands and grooves and fully stress-relieved. Each is also warranted against defects in material or workmanship.In addition to the two categories above, these barrels also are furnished in two grades: Stainless Steel Match or Chrome-moly Match.

Stainless Steel Match Grade Barrels
Simply the finest available to the competitive shooter. Heat-resistant stainless steel generally extends the accuracy life of a barrel over chrome-moly. In addition, stainless steel machines better than any other barrel metal, providing a somewhat higher quality bore surface. Hand lapping in every Shilen stainless steel barrel then achieves what we believe is the ultimate bore finish. To meet Shilen Match Grade criteria, groove dimensions must air gauge within 0.0005" of our standard diameter and vary no more than 0.0003" from end to end.


Chrome-moly Match Grade Barrels
The same precise, uncompromising bore dimensions as Shilen's Stainless Steel Match Grade. While these barrels possess a beautifully smooth interior surface, the bore can be brought to a finish approaching that of a Shilen stainless steel barrels by specifying the optional hand-lapping process.


Contours and Dimensions:





Silhouette Pistol Barrels measure 1.25" X 14" and are available unturned or turned in all three grades. These barrels are also offered Prethreaded and Chambered by Shilen, requiring some final fitting by a gunsmith. Select any desired caliber and twist from the Calibers and Twists data sheet.

*NOTE: WE DO NOT DUPLICATE THE CONTOURS OF OTHER MANUFACTURERS.

Standard Pistol Barrels measure 1.20" X 14" and are available unturned in all three grades. We will turn Stainless Steel Match Grades to a smaller diameter for an extra charge. Standard Pistol Barrels are offered only in the calibers and twists below.

Shilen Triggers


Hunters and competition shooters have precisely the same needs when it comes to triggers. Both need an extremely reliable trigger that releases crisply, without "creep" and inconsistency in pull pressure. Both require predictable, positive adjustments for attaining trigger performance tailored to a specific use.

All this is built into every Shilen trigger. These gems of materials and machining are steel bodied. All moving parts are heat-treated and sear surfaces are ground and polished. Even the allen head adjustment screws are heat treated!

Both triggers fit Remington Model 700 and 40X actions, as well as rear-grip XP-100 silhouette pistols.

Shilen Standard Trigger
This specialized hunting trigger is three-way adjustable for weight of pull, sear engagement, and overtravel. Pull weight is adjustable from 1 1/2 to 3 pounds.

Shilen Competition Trigger
Featuring a crisp release ranging from 2 to 6 ounces, this match trigger is easily set for pull weight, sear engagement, and overtravel. It cannot be adjusted heavier than 6 ounces.

Shilen MicroJacket Bench Rest Bullets


An article appearing in the January, 1996 issue of Precision Shooting Magazine touched off an uproar in the benchrest community. The article announced that for the first tie in history a custom bulletmaker had begun making its own jackets. That bulletmaker, Precision Shooting further reported, is Shilen, and the jackets are called MicroJackets.

Why did this news cause a stir among readers of the International Benchrest Shooters Association's official journal? Ever since bulletmaking began, the difficulty of obtaining good jackets has been recognized as the greatest obstacle to swaging accurate bullets. And without accurate bullets, benchrest competitors become extremely irritable.

Before we began making our own jackets, Shilen, like any other custom bulletmaker, obtained jackets from the usual sources. Problem is, production jackets often exhibit thickness variations of a disastrous .0005" to .0008". In contrast, Shilen MicroJackets are held to .0003" maximum variations, with an average uniformity of .0001" to .0002". Why is this important? Thick and thin areas in a jacket cause bullet imbalance, much like an out-of-balance tire. The bottom line is this: making our own jackets has finally given us total quality control over every aspect of the bulletmaking process.

Are these remarkable bullets jealously reserved for benchrest competition? Absolutely now. Varmint hunters are finding that genuine benchrest bullets are the very best choice for vermin.

When you're ready to see what the world's most precisely made bullets can do for your rifle, give Shilen MicroJacket Bench Rest Bullets a shot.

Should I "cryo" my barrel?
If you have heard that the cryogenic treatment stress relieves steel, this is false. We have measured the residual stress in 4140 and 416 steel with a process called x-ray diffraction. After much R&D, we have not been able to measure any changes in molecular stress after cryo treatment. For this reason we do not endorse the cryogenic process, but we can safely say that it is not detrimental to the barrel either.

I want a chamber that I don't see on your list. Does that mean you can't make it?
Not necessarily. Every day someone "re-invents the wheel" and puts some grandiose name on a cartridge that has been in existence for years. A good, current example of this is the 260 Remington.ÝWe've offered a 6.5x308 Win. for many years. Jim Carmichael and Remington just conspired to legitimize it. We offered a 7 mm x 8 mm Rem. Mag. long before Layne Simpson named it a 7 mm STW. Be that as it may, it is a fairly simple task to make varying necks on different cartridges and turn them into something different. If you don't see a chambering that you want in our data sheets, pick up the phone and give us a call or E-mail us at comments@shilen.com. Chances are very good that we can provide it for you.

What do you mean by "Throat to a dummy cartridge"?
Factory rifles are made with throats long enough to accept the largest bullet that is offered in factory ammunition for that chambering. So if the throat is long enough to accept a 200 grain bullet and you only want to use 150 grain bullets, then the throat is so deep you can't get the bullets close to the lands and keep them in the case. What this amounts to is the factory reamed out a couple of hundred thousandths (or more) of lands and grooves in the throat, which shortens the accurate life of the barrel by as much as 50%. All bullets and throats have a "preferred" stand-off or "jump" distance from ogive of the bullet to the lands. Handloaders "tune" their ammunition by experimenting with this distance. Generally speaking, all calibers tend to shoot better when close tot he lands. Weatherby rifles come with about 3/8ths of an inch of "free-bore" in them to help compensate for the high pressure the factory ammunition develops. If you intend to shoot factory ammunition in your rifle, then stay with a factory length throat as shortening the throat will probably show little or no increase in accuracy and may even prove detrimental. In fact, in Weatherby cartridges, this free-bore is necessary to avoid pressure problems when using factory ammunition. However, if you intend to hand load for your Weatherby cartridge for better accuracy, then throating to a dummy round is the ticket. When you send us dummy rounds to throat to you are, in effect, asking us to make the chamber to fit your ammunition instead of you being required to make your ammunition to fit the factory chamber. Make sure that your dummies will fit into the magazine of the rifle. If you aren't sure what to do. Don't be embarrassed. Just pick up the phone, call us, and we'll help you get it straight.

What do "turned" and "unturned" mean?
Turned, profiled, and contoured all mean the same thing. These terms all indicate that a barrel blank has been turned down on a lathe to a rifle barrel configuration or contour. We make most of our barrel from 1.250" diameter steel. Before the blank has been profiled, it is referred to as an "unturned" blank. Only gunsmiths who have tapering attachments for their lathes and prefer to turn their own contours use unturned blanks. If you are wanting to order a blank for your gunsmith to install and the gunsmith does not have the equipment to contour the barrel, then the turned blank is what you are looking for.
Back to top.


What kind of finishes does Shilen offer for barrels and actions?
STAINLESS STEEL BARRELS-- In Stainless barrels your finish options are "left in the white" which means a bright polished finish, "glass peening" provides you with a non reflective "matte" finish, or "teflon coating" with black teflon to more closely resemble a typical matte finish blued steel appearance. CHROME MOLY STEEL BARRELS-- When re-barreling a rifle with a Chrome Moly Match Grade or Lone Star Grade barrel, the barrel must at some point be either blued or teflon coated to prevent rusting. We offer two blued finishes for chrome moly steel barrels. The blued options are polished and blued or glass peened and blued. The polished and blued finish is done by polishing the barrel with 180, 240, 320, and 400 grit sanding belts, finishing with a Scotch BriteTM polishing pad, and then bluing. A "glass peened and blued" finish is accomplished by first polishing the barrel with a 180 then a 240 grit polishing belt. The next step is to "peen" the surface by spraying it with fine glass beads under high pressure to dimple the surface texture to reduce the surface refection. Finally, it is blued. Action finishes are done in basically the same manner. Barrel finishes and action finishes are priced separately. To glass peen and blue the barrel and action will cost $60.00 for the barrel and $60.00 for the action, for a total of $120.00. STAINLESS STEEL ACTIONS-- Finishes available for stainless steel actions are Polished (In the White), Glass Peened (Matte), or Black Teflon Coated. CHROME MOLY STEEL ACTIONS-- Finishes available for chrome moly actions are Polished and Blued, Glass Peened and Blued, Black Teflon Coated, or Electroless Nickel Plating. The Black Teflon Coating and Electroless Nickel Plating are only available in Matte finish. NOTE: Actions have been made from various types of steel over the years. Some actions have parts such as trigger guards and floor plates that are made of non-blueable materials. In cases such as these, our only option is to coat the non-blueable part(s) in Black Teflon. Some action materials will not Polish and Blue without turning to a red or purple tint due to their inherent metallurgical properties. In these cases, many times they can be glass peened and blued. This is an unavoidable situation, and many times we cannot forecast the results of polishing and bluing an action. We just have to try them and see. If your action will not accept a polished blue finish, we will first contact you and inform you of the problem prior to glass peening and bluing the action.

What is a pre-threaded and chambered blank?
We offer blanks that have been finish chambered, threaded for the appropriate action, polished, and crowned at the customer's requested length. The installing gunsmith needs only to modify the shank length of the barrel for the proper headspacing to be complete and no finish chambering is required. We offer these barrels in many different "wildcats" and "improved" chamberings to allow a gunsmith to be able to fill a customer's order without having to purchase a reamer they may never use again.
NOTE: Brownell's, Inc. in Montezuma, Iowa handles our "short chambered" blanks. These type blanks are only available through Brownell's and require the installing gunsmith to finish the chamber. In order to install one of these short chambered barrels, the gunsmith must have the appropriate reamer to finish the chambering. Once finish chambered, these blanks must be polished to complete the installation.
Back to top.


What is the difference in a "wildcat" and an "improved" chamber?
A "wildcat" is a cartridge that has to be made from an existing brass by shortening or modifying the existing brass just to be able to fit it into the chamber. An "improved" chamber is one where the improved brass is made by simply firing the cartridge in an improved chamber and allowing the brass to form itself to the chamber. Firing a 220 Swift cartridge in a 220 Swift Improved chamber will give you a fire-formed piece of 220 Swift Improved brass. Some refer to this as "blowing out" the brass. Once formed, the case now has less body taper, more defined shoulders and an increased powder capacity.
Back to top.


What about "fluting" a barrel?
Fluting is a service we neither offer nor recommend. If you have a Shilen barrel fluted, the warranty is void. Fluting a barrel can induce unrecoverable stresses that will encourage warping when heated and can also swell the bore dimensions, causing loose spots in the bore. A solid (un-fluted) barrel is more rigid than a fluted barrel of equal diameter. A fluted barrel is more rigid than a solid barrel of equal weight. All rifle barrels flex when fired. Accuracy requires that they simply flex the same and return the same each time they are fired, hence the requirement for a pillar bedded action and free floating barrel. The unrecoverable stresses that fluting can induce will cause the barrel to flex differently or not return from the flexing without cooling down a major amount. This is usually longer than a shooter has to wait for the next shot. The claim of the flutes helping to wick heat away faster is true, but the benefit of the flutes is not recognizable in this regard until the barrel is already too hot.

Can I use Moly coated bullets to break-in my barrel?
Some bullet and barrel makers say that the best way to break in a barrel that is to be used with moly bullets is to break it in with moly coated bullets. Others say to use uncoated bullets to break the barrel in, then start using coated bullets. We hear from a tremendous amount of top-notch shooters and gunsmiths and they all have their own opinions on this subject (as you already know). In compiling this wealth of information, we have come to this conclusion: There is no BEST way. Some barrels seem to break-in very quickly with coated bullets. Some seem to take longer. We've had shooters tell us that if a barrel didn't seem to want to really "come-in" with coated bullets, a few uncoated bullets down the barrel actually helped the initial break-in. Then they went back to the coated bullets with good results. Our recommendation is to load and tune the rifle with jacketed, uncoated bullets. Then try the moly coated ones.

How should I break-in my new Shilen barrel?
Break-in procedures are as diverse as cleaning techniques. Shilen, Inc. introduced a break-in procedure mostly because customers seemed to think that we should have one. By and large, we don't think breaking-in a new barrel is a big deal. All our stainless steel barrels have been hand lapped as part of their production, as well as any chrome moly barrel we install. Hand lapping a barrel polishes the interior of the barrel and eliminates sharp edges or burrs that could cause jacket deformity. This, in fact, is what you are doing when you break-in a new barrel through firing and cleaning.
Here is our standard recommendation: Clean after each shot for the first 5 shots. The remainder of the break-in is to clean every 5 shots for the next 50 shots. During this time, don't just shoot bullets down the barrel during this 50 shot procedure. This is a great time to begin load development. Zero the scope over the first 5 shots, and start shooting for accuracy with 5-shot groups for the next 50 shots. Same thing applies to fire forming cases for improved or wildcat cartridges. Just firing rounds down a barrel to form brass without any regard to their accuracy is a mistake. It is a waste of time and barrel life.
Back to top.


How do I clean my new Shilen barrel?
As with break-in and using coated bullets, you will find many diverse opinions on this subject.
EQUIPMENT: Cleaning Rods: Use a good quality coated cleaning rod with a rotating handle. The rotating handle allows the brush or patch to follow the lands and grooves. A non rotating handle forces the brush bristles to jump over the lands and grooves instead of following them.
BRUSHES: Use a good brass or bronze brush with a looped end. Do not use a brush with a sharp, pointed end.
SOLVENTS:
Every shooting product manufacturer has their own miracle solvent, and most do the job as advertised.
BORE GUIDES: Highly recommended!
PATCHES: Flannel or cotton patches work the best. Either trim or fold your patch to insure that it will fit snugly into the bore, but not so tightly you have to force it. Forcing a patch causes the rod to flex inside the bore of the rifle. If you are using a coated rod, this usually won't hurt anything, but the uncoated stainless steel rods that some shooters use can batter against the inside of the bore and damage rifling.
PROCEDURE: Once again, many different procedures abound. All accomplish basically the same thing. Here's ours: With the bore guide and the brass brush on the cleaning rod, apply the solvent to the brush by dipping it in the bottle or squirting a few drops on the brush. Slide the bore guide up over the brush and insert the bore guide into the chamber with a twisting motion. Push the brush through the barrel until it comes out the end of the muzzle. Now pull the brush back into the chamber guide. This is one "cycle". Make one cycle for each bullet fired, then apply more solvent to the brush and repeat this procedure. Now, fold or cut the patch for a snug, not tight, fit. Push the the first patch all the way through the bore and out the muzzle. As you draw the rod back, the patch should fall off. Put on another patch and push it towards the muzzle until you can feel it touch your finger placed over the muzzle. Then draw the patch back to the chamber and push it once more out the end of the muzzle so that it drops off. Repeat this with one more patch and you are finished. If you are through shooting for the day, lightly wet a patch with a light viscosity machine oil to prevent or retard rust. Push this patch through the bore. Let it drop out the muzzle, and you are done.

How clean is clean?
We get this question many times and have a great deal of difficulty helping some customers understand that a rifle barrel does not have to be spotless to shoot great. Many times more harm than good is done in trying to get it that way. Picture a car's fender. If the fender has a small dent in it, then professional application of body putty fills the dent. When painted over, the dent becomes unnoticeable, and the surface of the fender is smooth and consistent. The same thing happens in a rifle barrel on a microscopic level. Removing this small trace of copper puts you right back to square one. The next bullet that crosses that area will, again, leave a small trace of copper. Similar to patching a pothole. All successful benchrest shooters shoot one or more "fouler" shots down the barrel before going to the record target. This is not to warm up the barrel. They are resurfacing it on the inside. Benchrest shooters clean between relays to get the powder fowling out, not the copper. However, since copper usually comes out with the powder, they know that it must be replaced to get "back in the groove". I've had shooters tell me they "cleaned their rifle for 3 hours to get all the copper out of it." Their next statement is almost invariably that they had to shoot 4-5 rounds through it just to get it back to "shooting" again. This tells me that in order for the rifle to shoot well again, they had to replace the copper they worked so diligently to remove. I have a 7x08 Improved that shoots the same 1/2" MOA after 15 minutes of cleaning or 3 hours of scrubbing and de-coppering. Personally, I prefer shooting to cleaning. The gist of this is to set a regular cleaning regimen and stay with it. If the accuracy of the rifle is acceptable with a 15 min. cleaning, why clean longer? I would much rather have people admiring the groups I shot than marveling at how clean my barrel looks on the inside.

Do I need an FFL to order directly from Shilen?
No. Since there is no change of gun ownership involved, an FFL is not required. We do offer dealer discounts to FFL holders, but an FFL is not a requirement to do business with us. We cannot, however, forward the rifle or barreled action to any other recipient such as stock makers, deep freeze processors, etc. We will only return the rifle or barreled action to the original shipper.
Back to top.


What is "air-gauging"?
Air gauging is the method used to determine the fluctuations of land and groove heights in the interior of the barrel by using a constant flow of air through a probe. The gauge is adjusted to a given mean using a true, determined sizer head. The probe is then inserted into the barrel. The operator watches the fluctuations from the mean as the probe is moved through the bore. Our air gauges are accurate to 50 millionths of one inch.
Back to top.


What is "button-rifling"?
Button rifling is done by pulling a solid carbide forming die (referred to as a button) through the drilled and reamed barrel bore. The button forces the steel into the lands and grooves without cutting steel from the inside of the bore. The pressure exerted by the button re-positions the steel.

Can Shilen make me re-loading dies from the same reamer used to make my barrel?
No. Re-loading dies require undersized tooling.
