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

The stainless steel acs mags oal is 2.317. The aluminum you can get up 2.270ish..

My Montana .300 RUM managed to kill an SWFA, and now wears a Nightforce. I'm confident it can keep 10 in an MOA or less. Now, the shooter?

I've had occasions where 3-5 rounds loaded long will work in a Pmag, but then they jam up if you load more rounds in the mag. I've never heard of an unmodified Pmag that will hold a full mag at more than 2.260" though, except for the "Six8" mags that were only for use in those specific lowers. Of course, some guys cut out the front of the mag to allow longer OAL; we had a discussion on that here last year IIRC.

Pretty cool if DW's Pmags actually allow a full mag at 2.275". I'd like to have some of those.

You guys ever tire of those statements from some individuals on the internet like, "me and my wife can shoot consistent 1/4" 10 shot groups" with a factory rifle and factory ammo. You point them to this thread and their yap instantly slaps closed... I don't know about you guys, but it's cold here and snowing. Nothing better to do than work on an old washing machine that just took a crap and surf the web... At the least, you Cali guys can go and do some shooting for me, since I'm stuck at the house... Just a note on shooting. I did go to the range late yesterday, right before and during a snow storm. I had installed my new SWFA SS 16x and couldn't resist. That thing dialed in so perfectly it wasn't even funny. Shot my first 10 shot group and thought damn, I may have this in the bag. Then I proceded to shoot my Tikka, then my model 10 predator 223. Went down to the range and checked the targets, came back, shot the Tikka 5 more times to finish off that 10 shot group. By that time it was snowing hard. I forgot to bring my walking stick, so I could see the target, so I gave it my best shot with the Savage. You guys would be laughing at that group. I'll post it if you want. I was so disgusted, I packed everything up and didn't even try to shoot the Tikka and predator again. Got home, threw the rifles in the shop on the floor and came in and had a drink.... I love the snow, but it does nothing to improve the group size, when you can't see the target. From what little i saw yesterday, the Savage rifle is still shooting great after the fall and the new scope is working great. I'll test the tracking out when I can go and shoot some steel.

Doesn't meet the requirements, but thought it might be interesting for some...




100 round group at 100 yards, from sand bag, with 8x scope= 2.44”.







LMT MRP 16” CL, with NF 1-8x ATACR-

How fast, Form? One mag right after another?

Asking for a friend ;-)

I counted at least 26 flyers. That's easily MOA all day long when you do your part.

I have that same rifle. It’s my fave battle rifle.

Never got above 237 degrees. 😉 Barrel was cooled to 99 degrees between each ten round group- no cooling for the others. Probably one shot every 3-4 seconds.


5x5 round groups, 3x10 round groups, 15 rounds, 30 round group.

Pretty cool, I'm thinking my AR10 308 could do about that well... However, your are using ball ammo. Not bad formid..

It's not ball, it's 77 gr SMK or NCC's. I think mod 0 is Sierra, model 1 is Nosler but I can't remember.

Oops, I saw where it said "ball" on the box. So, it's 77gr. SMK. That is MUCH better than the 55gr ball ammo I thought it was... Interesting. Thanks for pointing that out...

Now, that is so much different in fact that If I tried that with my 73gr eldm load in my Norththech defense, I'd be making 1 1" hole in the paper and totally wasting 90 bullets...

Well, this is not a submission in this thread, but showing that my rifle is back on track. 6.5 creed shooting good again. The target on the left was shot during really light snow, and the one on the right was during a full blown snow storm. I wasn't real happy that I couldn't see the target, but you can see the creed is back to its old self after dropping it in the gravel:



I'm just glad I didn't fu ck the crown up or anything like that... The new SWFA SS 16x with mil quad reticle is going to do the trick. I'm liking it...

Alright Hero, I haven't seen where all the scores are totaled up yet, not sure you've done it, but I certainly haven't, not one gotdamn HALF INCH ALL DAY LONG RIFLE, hell, I haven't seen a half inch gun ONE GD time either! ; ]

Where do all those other guys get rifles like that?????

Wasting 90 bullets or proving 100?



I actually patterned #4 buck today in my Benelli. Okie land is now #4 buckshot friendly so I had to try some just to see, nevermind that I haven't shot my shotgun in at least 4 years till today.

I shot pistols with numb hands, sighted in my BUIS's on the new AR and then went and shot 30 rounds with the Sionics barrel, it was so bad I didn't shoot but 3 10 round groups, the 4th wouldn't have been any better.

On the MK262, Sierra supplied the bullet but DOD wanted a cannelure and they refused. Nosler was more than happy to oblige and Sierra finally decided a cannelure wasn't such a bad idea...
It was supposedly produced with a "blended" powder that produced better velocity than anything commercially available. The Shooters World powder thread makes me wonder if that isn't it.

The top 2 groups are 77 NCC's and the bottom (supposed to be the ammo it likes) 55 NBT's. Not everyday is meant for shooting I guess.
Oh and I loaded 10, fired 10 with the 1-4 Trijicon scope but I bet the barrel didn't get above freezing it was cold today!

All you ever wanted to know about the development of Mk 262.

Nolsers never made to cut & have never been used in production product that I am aware of.

Development of Mk 262 ammo

Mod 0 is the nosler bullet.. I posted this before, blackhills has a perpetual boner for Sierra. They took a trip Sierra and convinced them to put a cannelure on the 77gr bullet. Which lead to the mk262 mod1 load. As they say the rest is history. I just picked up 500, 77gr Sierra for $120 bucks.

Yes, I did find a reference to MOD 0 being the Nosler bullet, not sure how much of it was ever produced. though.

Yeah, $120 for 500 77gr SMK's is a fair price.

I have no idea man. If you run across some let me know. Please!!!!!! You can even save the 1/4 moa internet guns for yourself. I'm not that picky. 1/2 moa would do it for me...

I've added it up. There are 8 guys that have proven they have "moa all day long" rifles here and that they can shoot them as intended. There has also been right at 21,000 views of this thread, so the rest of the guys are watching, thinking do I want to try this or not???.. Mostly it's or not...
