Home Forums Hunting & Shooting AR and Tactical Rifles 24HC MOA All Day Long Challenge

I'm not too much of a stickler with my AR's, but I don't want them to be too long for the magazine. I could really care less if they are from 2.235-2.255" OAL from base to tip of the bullet. I have a comparator as well, but it doesn't do anything any better than measuring from tip to base and taking an average. If you buy decent bullets, the odds are you won't see much of a variance anyway. I know where my bullets are in relation to the lands, I don't need a comparator to tell me what I already know.. I do fully understand the frustration with Hornady bullets, as it seems like they are always fu cking with the location of the ogive or changing actual bullet length for some damn reason.. I like hornady bullets, though. For the most part, they shoot very consistently and are quite a bit cheaper than sierra's. Now, it would be a good experiment to see how much the bullets vary while using the comparator on them. If it is the base to ogive dimension that is sporadic, I can see that affecting accuracy/consistency. I may just break out the comparator and do some testing. That would also be great information to post on the appropriate thread. 77gr SMK VS. 75gr. Hornady BTHP . Speaking of the sierra's, midsouth has a bunch on sale. 69gr SMK for $95.00/500 and the 77SMK for $109.59. Better get them while they are hot..

It was a nice day on Saturday so I took several rifles to the range for a little sighting in action. I'm going to start sticking with one load for every rifle instead of having multiple loads. Hopefully, this will save me a little coin. Anyway, one of them I took was my CZ527 in .223. It's pretty accurate and I had a good load with the 50 gr. Nosler BT, but I also had 14 50 gr. Sierra Blitz kings left that I thought I'd load up and see what happens. I used 25.0 grains of IMR 3031 and the Remington 7-1/2 or the CCI 400 trying to see which load I like better. I think I'll stick with the Rem 7-1/2.

I had a pretty good group going until the guy next to me started unloading with his SBR! The muzzle blast from that damn thing was horrendous and he was 10 feet away from me.

I can't get the pics to post correctly for some reason. And they're all turned wrong. WTF!

Looking great mr. Thomas. Looks like most, if not all, are sub moa groups. You do the math for us, but one target looks like a .645 moa avg. Im on my cell phone at work right now. Too bad the pictures are in a link. Other than that, thats exactly how you do it. Calipers are centered over the group too. We may finally have a 10th shooter to produce an actual sub moa score. Good job!!

I cannot get the pictures to post correctly on this site. I don't know what it is, but I can't get it right. The only target to score is the last one really. The first one was test loads with the 50 gr. Sierra and different primers. The last target is the 50 gr. Nosler BT and 25.0 gr. IMR 30301 and the Remington 7-1/2 primer. One group measures .640 and the other .850 for an average of 0.745.

When it comes to getting photos to render correctly here, I have found that sometimes there seems to be NO way to make it happen. I feel your pain.

Nice shooting, though!

Oh, I was looking at the .807 and .544 target, but I see the caliper says .599. My bad. When we first started doing this, guys would get pissy and say you had to go out, shoot that one set of groups and basically call it a day for all intents and purposes of the shoot here. We were told not to "cherry pick" our groups, so that is what I try to follow. However, I don't see a problem using the target where you are shooting different loads. Who cares? I really don't, but I don't know how the op feels about it. I'd call your rifle and your shooting "moa all day long".. Thanks for posting..

Photo's are easy as you know what, I won't use the f word this time. . USE IMGUR...!!!

Anyone shooting this anymore? Still a great shoot. As long as I have targets, I'm going to be shooting it.. Took 3 rifles out the other day. 2 AR15's and my new Tikka T3x 7mm08. I was just working on loads for my Tikka, so I'm not posting any targets for that rifle yet. I suspect it will be shooting sub moa way before hunting season though. But for now, I'll show results from 2 of my AR's, from the other day:

Scoped Semi auto entry:

Rifle: Spikes tactical/Northtech Defense (old faithful) chambered in 223 (CLE chamber). Windham weaponry stainless 20" fluted barrel. RTBA BCG, Matrix Arms Foxtrot 15" handguard, RRA 2 stage varmint match trigger, Spikes tactical ST2 buffer, Armaspec LPK, BAD lever, Gen 3 PRS stock, K2+ grip, Raptor charging handle, Burris PEPR scope mount with AR556 4.5-14x42 scope:

Target pic:

I knew I could shoot a better group than the first one, so I knuckled down and shot the rifle the way it was intended to be shot (group on right)....

Target pic with caliper laid over one group for reference:


I changed one thing on my load and was using R-P brass instead of my usual range pickup FC. The R-P is more consistent and better brass. The CCI 41 primers seem to be doing well...

Average of the 2 10 shot groups: .693 MOA

Second Semi auto rifle entry from 7-18-20:

Spikes tactical viking edition lower. Spikes upper. Fail zero nickel boron BCG, 6WOA, Armaspec LPK, BAD lever, CMC single stage 3.5 pound trigger, Noveske NSR 16.7 handguard, Armaspec stealth recoil system, Gen 3 PRS, K2+ grip, Burris PEPR mount, Burris AR 762 4.5-14x42 scope, 85gr Sierra gameking load. Average velocity 2,880 fps:

Target at 100 yards downrange:


Barely scraped by with a .946 moa average....

"Anyone shooting this anymore?"

Nope, we hung steel at 1000 yards Saturday morning, I even missed a pistol match to do it. Shooting carbines with LPVO to 600, red dots and irons to 300 and my 22-250AI at 900 and 1000 has kinda messed up my whole routine.

At least you are shooting. That is the important part.

I shoot every weekend and sometimes during the week, just don't post much about it.

I’m about to do the MOA challenge later today with my M1 garand. It’s a fun shoot using CMP rules. 10rds slow fire prone, 10 rapid fire sitting starting from standing position,with 2rd enbloc flowed by 8rd enbloc, 10rd rapid fire from the prone starting from standing piston. Then last is 10rd slow fire standing no sling allowed. We are using 200yd 5V targets.

I shoot way more than i post about it as well. Shoot those targets every time i go out. Never go home without shooting a few moa targets. Ill be shooting my 6.5 cm tonight with a different compensator on it. Why have a thread or even a forum, if you arent going to talk about shooting your rifles? Thats what this thread was for.

First time poster here in the Challenge thread. I shot yesterday in the heat. Scoped semi-auto entry

3. Picture of target with calipers (I used OnTarget to get the measurements, and wrote them on the target).


4. Mega Arms forged upper and lower, 21inch X-Caliber 223Wylde 3groove-8 twist barrel, LaRue MBT-2s trigger, scoped with a Bushnell Forge 2.5-15X. I was shooting 69gr SMK's over 25.1gr Varget in LC cases with S&B primer.

5. Group 1 0.752moa. Group 2 0.863moa. Avg 0.808moa

Nice shooting 458minmag!! Looks like that 69 smk works well for you too. Im glad to see someone is still shooting. Im happy anytime i shoot anything sub moa in this challenge. .8 moa is damn good with an AR.

Thanks BSA. I have been watching this thread over the years, and I'm impressed with everyone's shooting. You've posted up a lot of fantastic targets.

I have shot several 5x5 targets with that gun, but this was my first 2x10 shot format. I have to say that I was getting a litte anxious as I got up around 8 rounds and the groups still looked good through the scope. A lot of fun.

You did great. That anxious feeling gets to all of us. Ha ha.. That's what makes it such a challenge. A lot of us here have commented on how one of our groups are great and then things fall apart. Or things fall apart even before we are done with our first 10 shots. I've noticed sometimes I'll throw the 8th shot because I get too confident and then I'll have to make up for it on the 9th and 10th shots. Its great practice for my local competitions though, as we shoot 10 shots slow fire on NRA targets.

Greatwapiti, here's where you want to post those targets you fu cking puzz..
