I'm in the process of building a 22-250. I have everything except waiting on the barrel. I'm using a 24" McGowen. It sounds like the 22-250 can have cycling issues and feeding issues. I went with the .100 gas port so I should be able to gas it up if I need to. The case taper is very close to the 22 Nosler which I have no problem with. I guess I'm not afraid of a challenge but have any of you guys built one and had good luck with it.

Ar 10 I assume?

Yes, DPMS.

I think over gas is one of the issues.
Feed angle from mag is the other thing that causes misfeeds.
Ar 15 rifle gas tube length is 15". Ar10 is just over 15" like 15&3/8. Gas tube should end in the middle of the cam pin cut out in the roof of the receiver.
I would recommend an adjustable gas block and a heavier buffer.

I do have an adjustable gas block. I opted for the bigger gas port so I could adjust it if I needed to. If I load a 10 round P mag the first 5 or 6 do catch the magazine with the case mouth when I manually slide them forward. I'm thinking a pound bolt and maybe bevel the mouths a little more they should slide past it. Time will tell.

I remember the magazines running a $150-$200 each on these from Alex pro which made me steer clear of the chambering and go the 243 route (2ce) since it shoots just as flat, or flatter, with 55 grainers. I would assume there has to be some fabrication to make it feed and function with just the mags alone. Keep us posted along the way.

I did see the Alex pro for 180 and probably will go that way. I am going to MacGyver 1 10 round mag and take a chain saw file to it and buff off a couple channels for the case neck to clear and see what that does. The thickness of the brass is what's catching.

Have you considered a 243win barrel instead??

I put a 243 together in January. I really like the gun but want to try a 22 250 in the AR. If the 22 250 doesn't work out I'll put a 308 barrel on it.

What about a dtech wssm?

The biggest draw back to the WSSM is brass availability. A buddy has a 243 wssm. I helped him look for brass or factory when availability was good, it took a year to find loaded ammo. He bought 15 boxes for the brass. Last night I loaded a 10 round mag with 22 250 and cycled them through my 243. Didn't let the bolt close but let the bolt hit them fast. It chambered a 22 250 every time. Probably doesn't mean anything but I'm taking it as a good sign.

Sometimes wssm brass is all I could find for sale

If it “really” worked 100% reliable there wouldn’t be expensive proprietary fabricated magazines and there would be 22-250 ARs all over. I would have to guess the 22-250 is a unicorn caliber in an AR for a reason. Imo I wouldn’t think it takes a special magazine either to feed and function.

That's the best thing about an AR. If the 22 250 is a disaster I can order a different caliber and replace the barrel in 20 minutes. I'm determined to make this thing work though. Lol

You can do it!

For your next trick, figure out how to shoe horn it into an ar15 like Oly did. I still kind of kick myself for not snagging one of those.

If you take a single stack 450 Bushmaster magazine it will run fine in a WSSM. I have a 25 WSSM and it is quite a fun little round.

Start filling that piggy bank.

Greg

I know, right?! I recently saw one on GB go for 2700 or so iirc.

Bear creek Arsenal just announced they will be making a 22-250 AR. I’ll be grabbing one when they do.

Interesting. I’ll have to keep up with that to see the details and how it works out.

Here’s the link

https://youtu.be/zNziI8DXaz0

Ah, AR-10 platform. Might still be in the cards unless it’s a bunch of proprietary stuff where you can’t swap out components and get the weight down to reasonable. It would be very nice to have one lower and be able to swap between 22-250 and 243 uppers. I’ve been back and forth so much on doing a 6 ARC, but if this develops into something fairly decent, I won’t think twice about it again and I’ll do just that, 22-250 and 243 switch gun.

My barrel should be here in June. I've seen the Alex pro magazines. Seems odd to me that I can load a 10 round mag, lock the bolt back and chamber a round every time in a 243. I either made a costly mistake or it will be a winner. Good to see there might be an option.

Keep up the good work.

I too saw the BCA 22-250 deal. Looks like they have modded a amend2 mag to run the 22-250. I’m curious to see what has been done to the mag in order to work. I run a amend2 mag on my 6.5CM with no issues. So I’m optimistic

BCA saw me coming, I ordered one. Like a fish with a hook in his mouth.
Like someone above said, I like a good challenge.

Alex pro seems to have the magazine issue figured out if the BCA modded mag don’t work.

Down the 22-250 rabbit hole 🕳

Didn’t know they were available yet. I se they are listed at $584 and $599. Figured they would be about the normal $399 like all their other uppers. I’ll hold off for now since I already have two of their 243’s that I don’t shoot.lol

BCA had a video out that I don't see anymore that showed the magazine. It looked like a standard gen3 magpul but had a plastic insert on the front side of the magazine to make up for the short 22 250. They don't have the mags on their site but I would hope their not going to be 200.

I got a email a few weeks ago- was available for pre order starting 5/18. Says it ships in 2-4 weeks.
On the email it stated, they use a modded magazine.
The picture on website is a Amend2 magazine.
I pre-ordered one. Won’t get around to building it till fall-ish. Machining to be done on lower and I just order parts slowly so it don’t seem so expensive. Ha ha

Pre order price was $509 if I remember right.

I would assume the magazines that come with the upper are priced similar to $200 from the $399 to $599 price increase over all the other AR 10 upper prices listed. When the hype is over on them in 6 to 8 months I’m sure they will priced in line with all their other uppers. Like anything new the company is going start out with a higher, inflated price and figure they will always get more money from the ones of who have to to have it first. After waiting and thinking about them, and remembering my 243 BCA issues, I’m not in a rush for it anymore. I’ll let the bugs get worked out of them and let the prices drop after the they sit on the 2nd run for a while. I don’t want to get a dud and wait almost a year to get a working upper back like I did with my 2nd 243 from them. I will be curious to see how well and accurate they shoot… or don’t shoot first from the Guinea pigs that buy them first. Who ever buys one make sure to post your results here. I’m sure they will probably function and shoot fine. Once again a proprietary magazine for it which tells me the OP is going to have to fabricate something in his magazine to get it to work reliably.

i aint picking one up till they use another finish besides parkerized.

i'm also leery about the 1:14 twist. i know the caliber is geared around 55gr stuff... but as a reloader i want options. i see other folks offering them in 9 twist, etc.

the combo of the twist and finish made it a hard pass for me for now.

I'm thinking since bear creek uses a DPMS lower their amend 2 22 250 mag would work in my Aero lower. Going to buy a couple and find out.

A picture is worth a thousand words but the 22 250 does work. A specialized dynamics video, he said you can run 7 rounds in any 10 round mag or 5 in a 5 round mag no problem. Mine cycles 7 rounds no problem. That's works for me.

So I picked up one of these BCA 22-250s. Shot it last night a few times. I had two misfires with a dimple on the primer but not a deep one. A couple of the primers on fired rounds had holes in them and at least one more was cratered. This was out of eight rounds. Have not messed with ARs as much what should I be looking for? Is this trigger related, firing pin?? It was factory Remington ammo. 55gr psp.

I would start by disassembling the bcg and making sure it's clean and the firing pin is free. I would also measure a fired case and check headspace. Make sure the bolt is rotating all the way when closing and I would also extract a cycled round to see if it is getting dented or beat up in the cycling process. Where is ejected brass landing?

I was standing in the back of a gator shooting off the cab sighting some backup sights. Cab is about 6 ft high. It was slinging them about 4-5 ft to the right kind of behind me. I will check some of that stuff. Thanks.

Well if brass is slightly behind it is not over gassed.

It’s possible you could have a ammo inconsistency problem with light strikes and pierced primers. Do the pierced primer rounds look like their smashed flat on the whole back of the case. The barrel nut might be loose, trigger group might be bad, bolt carrier might have issues. Is the firing pin half round on the end. Try taking the bolt carrier out of the upper. Push the bolt back into the carrier, take a screw driver and push the firing pin back and forth to see if it slides up in the bolt easy so it would hit a primer with no resistance. A new 110.00 bcg with a 100.00 drop in trigger and a tight barrel nut should fix it or the 30 day guarantee.

Thanks guys been busy the last few days and have not had time to look at it. I will check all this stuff and report back.

BCA a10 uppers require a DPMS gen 1 type lower. I would call them and make sure your lower is compatible, the cut(shape) between trigger and buffer tube matters. All factory ammo should run fine.

I also picked one up. Upper functions and cycles good so far. I’m 40 rounds into it now.
It did fail to load twice early on

When shooting Remington 50 grain jhp every primer blows a hole threw it where pin strikes.

Switched to varmageddon 55 grain and primers are near perfect after being fired.

I was shooting off tri pod and brass landing at 5 o’clock position.

I chalked the holes in primer up to Remington bullets… I may be wrong to assume this. Please let me know more

I would measure a fired case to verify proper headspace and chronograph it.
Pressure equals speed. If it's really fast the psi is really high lol. If they aren't overly fast psi won't be overly high.

Might even be worth turning the gas off, shooting one and measuring a fired case to eliminate case stretch from the bolt opening while chamber pressure is still high.

Thanks- here is a [img:left]https://ibb.co/ThrGW6t[/img] picture

Copy the BB code and paste it.

Thanks alf -
I’ve tried posting piks many mays in past. I never get it right.
Thanks again


Update: I have now tried 4 different brands of ammo. only these Remington 50 gr jhp seem to blow holes in primer .

I do not have a chronograph . Maybe in my near future though

Primers don't look excessively flat. Appears to be a few case head marks but hard to tell in that pic.

Looks like BCA lowered the price of their 22-250 uppers to $322 a few weeks back.

Update on my issues-

Ammo sent In , they were able to replicate the issue I had.
Refunded / gave me different caliber replacement ammo, as 22-250 not on schedule to be ran anytime soon.

I will just stick to running Nosler .

Gun is functioning smooth after nearly 200 rounds now.

And it sold for that much?

OK I have a few more rounds thru my 22-250. Still piercing a primer ever so often seems to be running a little better. Took it down and cleaned it fairly good and everything seemed sticky like that shipping lube sticky. So cleaned and oiled everything. Only have about 15 rounds thru it so far. Noticed my brass is ejecting about 5 oclock. Going to shoot some more and see if it breaks in a little more. Have not shot for groups yet.

The father in law bought a 22" BCA 22 250 upper. Accuracy is very good but it's a side charger and he's trying to use a brass catcher. Causes a few problems. Haven't had a pierced primer yet. Definitely worth the money.

comments say that will work on side chargers

Amazon

After reading some of the issues with blown primers and feeding problems, I called and spoke to a customer service rep at Bear Creek and he assured me that those issues with the 22-250 had been resolved and he recommended the correct P-Mag to purchase. I went ahead and purchased the rifle and mag. Took it out this morning just to see if there were gonna be any issues. First issue is the bolt release would not release the bolt...no matter how hard you pushed on it. Decided to just pull bolt back and let it fly home. Second issue was the bolt drove the round into the locking lugs driving the bullet into the casing. Decided to chamber a round by hand and fire the gun to see if it would cycle. No dice, cycled fired casing out and nailed the next bullet against the locking lugs just as before, pushing bullet into casing. Guess I'll have to send it back.

are you trying reloads or factory ammo?

Factory Ammo

Mine seems to be working better. But all these issues keep popping up. I found another instance on YouTube guy was having similar problems. He sent his back as well. I will say I went into this thinking it is a cheap gun I might have issues. But every so often you have to take a few chances. As a side not no one has ever complained about accuracy.

I can't speak on accuracy, can't get my rifle to get to that point!

The father in laws would randomly have cycling or locking back issues with different bullets and powders. Today I drilled out the gas port and now its running without a glitch. We both were shooting 1 inch groups at 200 yds today.

My issue is two fold. One, the bolt catch release wont work (magazine or no magazine). Two, the bolt drives the bullet into the locking lugs at a fairly straight angle which drives the bullet into the cartridge. I doubt mine is a gassing problem as it does pick up the next round after cycling the spent cartridge out but it is pushed into the locking lugs. None of this happens without placing a fresh round into the chamber by hand however. I am really disappointed in this product. I was looking forward to having a long range tack driver for coyotes. Wish there was a fix for it but unless someone can come out with a special magazine to ramp the round up at the correct angle, I'm afraid these issues are gonna persist. That still doesn't address the bolt catch release issue either.

Are they BC10 in 22-250? If so, what mag are you running?

He has ASC and Magpul gen3. It didn't seem to matter what magazine he used. First I tried a silent capture spring. Then cut coils off his original buffer spring that helped but only ran 100% with hotter loads. I drilled the barrel gas port without trying an adjustable gas block and it seems to have worked. Cycled milder loads at 4 o'clock and locked back.

I hate to do anything to attempt to fix whatever is ailing my rifle in fear it would cost me the warranty. Just picked the rifle up Friday. Just seems like too many issues for a new rifle. Ammo is too expensive to keep jamming bullets back into the casing too. I just feel like these issues should be addressed by Bear Creek and since they are NOT NEW ISSUES, they should have been fixed by now. Bad news spreads fast and if Bear Creek wants the reputation as a company that makes products that have alot of issues, I imagine they won't last long.

I've never been a fan of BCA, they have their work cut out, ARs have been around since the 60s and not one single quality manufacturer has gotten the 22-250 to run 100% and I doubt BCA will get it done.

Did your upper come with a bca magazine?
When they released the 22-250 they were using a modified amend 2 magazine .
It functioned near flawless. I use that with mine.
I have tried to buy another magazine and they told me this in email:

These magazines are no longer in production.
Try a 10 round magpul mag- they work with multiple types of failures.
And to also try a utg 25 round mag - they work as long as not full loaded.

I raised [beeep] with customer service- got no where. Basically I told them in the end they are a bunch of idiots to
Discontinue a product that allows their uppers to
Function correctly. They don’t care what customers have to say.



My best advise- try to find an original modded bca amend2 mag.
Or bite the bullet and buy a apf mag

22-250 BCA original magazine


Here are a few pictures of the original magazine that came with my BCA Upper .

It works near flawless.

Shooter, mine was a complete rifle already built and it came with no magazine. Prior to ordering, I asked about the issues and was told by customer service they were fixed. I asked about the magazine and was told that the PMag LR/SR Gen 3 was the correct mag to run.

How is the Amend 2 modified? Is it possible to modify one at home or is it machined differently?

I did some digging.

Talked to amend2- they were regular 308 mags sold to BCA

Then BCA made/modified follower and put a spacer in front of follower to keep bullets to rear of mag.

I am not sure it can be copied. Maybe someone with some skills and 3D printer could copy my follower and spacer. Then put them in a amend2 10 round mag.

I posted piks- the grey part in front of follower is the spacer. Goes to bottom of mag to keep bullets back in mag .

I am very tempted to buy and try a APF Armory mag.

But not sure on the $180 price tag.

One guy here- I talked to said it’s the only way he could get his to function. He built one- didn’t buy a bca upper.
He seemed very knowledgeable.

I will prolly use my BCA mag untill it starts to fail and then try a APF armory mag.
My .02

I built a 22-250 and took the advice of a Specialized Dynamics video. Because of the taper of the case 10 rounds do hang up in a 10 round mag. 7 rounds work without a problem as long as it's gassed right and everything is built right, like any other AR. The FIL's 22 250 just needed more gas. It sounds like it's a hit or miss with BCA.

Here is what APF has on their site regarding their gold plated 180 dollar magazine: "***MUST BE USED WITH AN APF 22-250 CUT BCG, AND APF 22-250 BARREL***

APF CANNOT GUARANTEE ITS FUNCTION WITH OTHER PARTS.

BCA however does recommend the Amend2.....

When I was waiting for my barrel to come in I checked into APF MAGS TO. I don't know how many rounds you put in your magazine but anything over 7 will set lower in the magazine and not chamber right. I built a 243 and when it was new it liked to jam the slim bullet in the feed ramps and stop. It came out of it. Some feed ramps need filed down to get rid of sharp edges. Not saying that's the problem your having but sometimes a good slap up on the bottom of the magazine can help.

5 rounds max here in Michigan- law

I have an amend 2 I only use 5 rounds at a time so far.

Two years ago I built a 22-250 with Aero M5 lower and upper with a X-Caliber barrel. Downloading Pmags did help with feeding reliability but every so often would jam a round straight forward and smash the bullet into the case. Broke down and bought an 8rd APF single stack mag. My aero bolt would get hung up on the mag. Called APF and said they only recommend their BCG so I bought that too and ran it this year with no feeding issues at all. I was so far into it I just wanted it to run so I spent the extra money to have a reliable 22-250 AR10.
