Shot again with same setup as my previous post, but this time followed the "aim small, miss small" adage. I reduced the aiming points on my target to be 1/2" diameter circles instead of 1" squares, and I could feel that change making a big difference as I was aiming each shot. Very helpful and effective.

Rifle is the Howa KRG Bravo in .308. This is the Howa 1500 short-action supplied with the KRG Bravo stock. Mine has the factory 24" barrel, which is 1-in-10 twist.

Bipod is the Magpul, and its swivel feature works great for me.

I'm shooting factory Federal GM308M (.308 Gold Medal Match, 168 grain).

My rear bag is homemade and measures 8" x 5" x 2" (meets the less-than 96 CI rule). I have to squeeze the bag to get and hold proper elevation, as per the rules.

Images below. This is at DPRC, in North Carolina. Much better groups than my last target.

Is there a semi auto only 1 MOA challenge? I need to feel better about myself.

Yes, SPR division is basically centerfire semi-autos.

Here's my submission.  Forgot to take a picture of the target down range at 50 yards, though .  This was shot for the .22lr magnified optics division at 50 yards.

Here is the rifle - CZ 457 Varmint Precision in .22 LR with a Vortex Viper PST Gen 2 3-15x44 (shot using Eley 40gr Tenex).  I only used a front rest.  The range provides sandbags but they're pretty large and my guess is they are not allowed due to the size, so I didn't bother using one.


Here is the target.  The 3 shots on the top left can be ignored and were just fouling shots since this gun likes to usually throw one of the first shots on a cold bore.


...and here are the 5 groups.  I apologize as I do not have calipers so I used the BallisticX app for measurements.






.22lr magnified optics 50 yards, Zeebz: CZ 457 Varmint Precision .22lr - KRG Bravo chassis - Vortex Viper PST Gen II 3-15 x44 - Eley tenex 40gr flat nose. Groups: .481"/.457"/.555"/.370"/.495" = avg. .471" = .899 MOA

ETA: I also had a witness. @southerncross

This was shot at the 8th Annual GAHTF MOA match.  Multiple witnesses.  Target was scored by the match scorer, not me. @redgoat @southerncross @GAHunter95




Bolt Division, 100 yds, akh223,  Savage 10FP .223 - Pac NOR barrel, Bell and Carlson Stock - NF 12-42 BR - 69SMK with H4895 Groups: .506"/.368"/.329"/.425"/.264" = avg. .378" = .361 MOA

Legit.  There were 50+ other witnesses as well.

Target.
I don't know what happened on the top left,  maybe wind. Three did go into one hole though.

Excellent shooting!

Impressive! My 77/17 wasn’t nearly that good!

Built my first AR 15 last month, heard about this challenge from reddit and made an account just to participate!

Thank you, this was a lot of fun, I'll probably do it again with my 22LR next week :)

@SpeyRod

I had a 77-17 as well. It was pretty good, but not as good as my 77/22.

Trying out some new ammo in the 77/22… very promising so far!

If you get a chance try the Aguilla super extra 40gr lead. It is noticeably better than everything else in my savage.

@akethan

As much as I’d love to try this, my sport is excluded by the rules. I shoot NRA/CMP High Power, specifically with Service Rifle. My rifle is optimized for shooting at a bullseye with a 6 MOA aiming black.  Finding a piece of paper to hold five 6 MOA aiming blacks is probably do-able, but the ban on shooting jackets is a hard stop.

Any chance of making another division, specifically for us NRA/CMP competitors?

Here an example from this morning’s practice, ten shots prone at 200 yards, slung, with a coat, on a Shotmarker eTarget.  The X-ring is 3” at this distance.

It'd be you and me. Odd, jackets and 20 shots were allowed tolerated for service division 8 years ago.

As a fellow Service Rifle guy, the jacket helps with standing only. Why would you not shoot this challenge because of that rule, when you'd more than likely be shooting from the prone position?

Not an official entry because I haven't loaded pics and because I may have used a rear bag that's too large (Precision Underground).  But I did attempt the challenge a couple of days ago with some surprising results.

First tried it with my Tikka TAC A1 in 6.5 CM.  Shooting Prime 143gr. ammo.  Figured this would be the easy one, since I always shoot my bolt action guns better than my AR and feel I can generally shoot better than 1 MOA.  Turns out I can't - at least not for the challenge.  Results were approx. 1.1", 1.1". 1.3". .6" and 1.1"  What was really frustrating was that I seemed to have one flyer in all but the .6" group - usually the first round.  So that was a fail.

Then I tried the challenge with my CLE 18" AR15 upper with a Krieger barrel 1/7.7 twist.  Shot AAC 77gr ammo.  Results were approximately 1.1", 0.75", 0.75", 0.8" and 1.3".  The last group would have been my best with first four shots being about .6" and then the 5th shot being the worst flyer of the day and really opening things up.

Again, not an official entry since I don't know how to post pics (do I have to upgrade my membership?).  But really interesting exercise that emphasizes how important consistency is and how not being able to throw out those supposed flyers can really open up your 5 shot groups.  Makes it clear that these two rifles would be shooting bugholes if the guy behind them could improve his consistency.

Still basically pretty happy with my AR15 results, and definitely plan to reshoot with my Tikka because I know I can do better.

Still some damn fine shooting if you ask me.

If you want to use the image hosting here, yes a membership of properly level is required. However, you can host the images someplace else and then use the links to display them here. I like Imgur myself.

Good luck!

Actually went back to the range today with my Tikka TAC -A1 because I was so disappointed with my earlier results.  Knew both me and the rifle were capable of better results.  Using same Prime 143 gr. ammo did about as well as I'm capable of.  Following 5 shot groups at 100 yards- .7", .4", .45", .8" and .6" for an average of approximately .6"  My best explanation for improved results was that I wasn't getting the first round flyers that I got in my previous session.  Only change I made was to insert the magazine on a closed bolt, rather than an open bolt.  Not sure if this somehow impacted how the round was fed into the chamber, or because I was cycling the bolt on each shot, rather than last 4 shots, I was getting behind the rifle exactly the same way each time.  Or maybe I was just shooting better today.  But results were much better.

All groups on a single 8.5x11 piece of paper, so no cherry picking of groups.  Also, except for two shots to warm up the barrel, these were the only 25 shots I fired from the rifle today, so it didn't take me 4 tries to get these results.

So I'm now considering upgrading my account and actually posting pics, so this (and prior groups with an AR) can be an "official" entry.  At least it will be fun for others to see my setups.  Still not sure this will count for the contest, since my rear bag may be a little too big.  Used bipod up front for both rifles.  Also, don't have fancy measuring app. to measure groups, so my measurements could be off by a little bit, since I'm just using a tape measure.  

Finally, I will say both groups say a lot about the inherent accuracy of the rifles.  I have no doubt that I am less than perfect in maintaining consistency and a better shooter could probably knock about .2" off my averages (particularly my AR).  Still an approx. 1" average with my AR (even with a really crappy flyer) and approx. .6" average with my Tikka, both shooting commercial loads, says a lot about what these rifles are capable of.

Two weeks ago I switched ammo to 6.5 Creedmoor Sig 140 grain OTM Match.

Both days were at 100 yards. Sorry for the crap pics, I’m new and still learning the app.

Sept 30 will be the next GA HTF MOA Challenge shoot.   Hopefully we get some good entries!

9th year!

Hopefully this is merely a placeholder. I decided to try a new load the night before MOA #9 (changed up brass/primer/charge weight). Unfortunately, I shot the wrong target initially and had to use a different load to finish up to get 25rds. Doubt I’ll have 50+ witnesses the next time I try it, but the load has potential when the barrel has been seasoned.

Is that the Valkyrie?

One of my 223 barrels. My 22GT posted 1 insane group and 3 good groups and 1 that went all to pieces. Hoping it’ll settle down now that it has 75rds on the barrel.

Maybe so you post some outstanding group consistently. We need more pictures and information on the .22GT. I missed that one. Was it just one round that screwed the group or multiple?

I appreciate the kind words.

I think I know the issue now. The weekend before the event I decided to add a brake so I wasn’t swapping suppressors around. The brake attachment instructions call for using blue loctite, which I didn’t do since I was just “testing it out”. Last night I noticed that the brake had loosened and was hand tight. It likely walked on my last group and could have impacted the random fliers in the other groups.

My load development targets have averaged in the .3’s before I added the brake.

A couple pics from the 9th Annual MOA shoot.
