Well, after a case of severe boredom lately and then looking into a few threads about reloads, accuracy/precision, playing with Sierra Infinity Suite and trying to get my scope dialed in for using mil-dots holdovers for a few hundred yards, I thought I'd post this thread.

I've shot mostly 3 or 5 shot groups to determine accuracy of handloads. I thought I'd stretch things out to 10 shot groups to make it interesting. At 100 yards, of course.

I am refering to threads like The Trouble With 3 Shot Groups and Mean Radius.

Gun: Piece-built .204 AR with a 1:9 24" Shilen barrel, 10x fixed Bushnell scope.
Rest: Front sandbag rest, off of a bench. No lead sled/vice, etc. ...same as prairie dogs off the truck cab, standing in the box.

Hornady 40 grain factory:




TAC handloads:

25.7 gr. Benchmark TAC, new Winchester brass, Fed 205 primers, 39 gr. Sierra BlitzKings seated to Mag length, or 2.250"





Varget Handloads:

26.8 gr. Varget, 2x fired Hornady Brass, Rem. 7 1/2 BR primers, 39 gr. Sierra BlitzKings seated to 2.250".




I was kinda red-a$$ed that the TAC loads didn't group very well. It didn't seem like I was very settled in, so I dialed my scope over and down and tried to put 5 more rounds through the hole in the cardboard between the targets. Previously, I'd horizontal stringed TAC handloads.



So, on one hand it was good to get to the range after the rain, and cool to dial my scope to shoot through a hole, but still not happy with the groups of handloads. Never happy. smile

I pulled a dry boresnake through after every 10 rounds.

I had limited time between work and family obligations, so I didn't shoot any more groups and went to .22 practice. A person could throw a few of those "flyers" out, but you'd just be lying to yourself. Overall, I will spank a few prairie dogs with any of these handloads, but it'd be nice to beat factory load groups.

Im surprised none of those groups were tighter with the powders you used. Were you using front and rear bags??

Hornady factory loads through my D-Tech have been very hard to beat by handloading.

As in I haven't been able to yet.

You may learn something by running those aross a chrony and see what velocity you're seeing.

What trigger are you running?

The reason I ask is,because some of those groups look like they may be affected by trigger pull. Just my .02

No rear bag, just a front bag as a rest, and my other hand under the back of the stock. I could probably do better with 2 bags. I suppose the loads would be even better using a lead sled.

Trigger is a Spike's Tactical Enhanced Lower Parts Kit w/ Nickel Boron Trigger. Looks like this one:




Soon as I work up the funds to buy a chrony, I'll probably get one. Just another step in the endless pursuit. In the back of my mind, I think I need to work on my shooting technique/method; probably more than I need to work on more loads.

Thanks for the input.

Well thats not too bad with just a front rest. With a rear rest they will probably be cut in half. I have a hard time shooting tiny groups without a rear bag sometimes. I always use 2 bags or shoot off a bipod and rear bag when doing load testing.

I've shot some very decent groups using that technique.
