Most accurate ammo in your AR-10
10/5/2011 8:42:45 AM
I am trying to find what you all find as your most accurate ammo thus far in the AR-10. I tried some handload and they came out alright (within 1.5 moa) but I think I could do better.
Thanks!
Thanks!

In order of accuracy (of the ammo I've tried so far):
Hornady 168gr TAP
Hornady 165gr SST
American Tactical 150gr "M80"
I highly recommend avoiding Black Hills 150gr GMX. This ammo from my 18" 1:10 right twist barrel shoots consistently left of POA nearly 4" at 100yds. This is despite having the same weight and similar velocity as the American Tactical rounds that are surprisingly accurate for affordable general range ammo.

I'm a big fan of the 168 gr's for my AR-10 due to shooting at some distance for NRA high power matches.

168 gr SMK
44.6 grains of VARGET
FGM 210
Lapua brass

110 Hornady V-max over 49 grains of 4895.

H4895 or IMR? I am using IMR4895

Factory loaded Hornady 168 BTHP in my 1:12 20" chrome-lined will easily stay under 1 MOA out to 500 yards...past that, I think it is more me than the ammo or barrel.
Factory loaded 155 AMAX does fairly well out to 500 yards as well.

For me the Radway Green 147 grain mil surplus has been the most accurate, out performed FGGM in my rifle.

Of the factory loads I have tried so far, BH 168 gr. Moly.

Each barrel and rifle will shoot differently with various bullets, loads and cartridges.
If you are shooting sub 1.5 MOA groups at 100 yards with irons - you're very close to the limit for irons. Might think about getting a good scope/mount set to wring the most accuracy out of your rifle.
Try different loads and keep a record of performance. When you have found the best combination of bullets, powder, case and primer - you can start making small adjustments in powder charge and bullet seating depth.
You may find your rifle likes factory or even surplus ammo best - can never tell till you try.
YMMV

I guess I might just be expecting to much from irons. I keep seeing those groups from people on snipershide with 5 bullets all in 2 holes or so.

It's easy when you have the right equipment.

My rifle seems to prefer 168 Amaxs. Eagle arms carbine with 11.25 twist stainless HBAR profile barrel. This is about an 1.25 MOA gun 'till you find it's sweet spot. It looks like RL-15 will do this too but about 100 fps faster, I still need to verify. I got .75 MOA with 125 gr. TNTs and H-335, coyotes beware!

Irons or scope?
10/6/2011 9:03:06 AM
Mine really loves 168-gr Federal Gold Metal Match! It is under 0.5MOA shooter and I may have got a bit lucky as my upper is a Chromemolly Eagle Arms AR-10T barrel as opposed to the more expensive stainless Armalite tubes. I have printed sub 1-inch groups out at 200-yards with that gun using Fed Gold Metal Match ammo. None of my reloads have quite been able to match that load which has caused me a bit of frustration.
My optic is a 4.5-14x Leupold - no open sights to do that group

Hornady 168gr AMAX, I get about 1.25" groups on the average day when shooting off a bipod. I'm using a basic Eagle Arms 20" A4 upper that has been free floated. And, of course I'm using 5 - 15x scope to do it.
10/6/2011 8:31:52 PM
Mine really likes 168-gr Federal Gold Metal Match as well. The last time I took it out I was shooting steel at 650 yards with Hornady Superformance both 165 and 168 gr and I was amazed at how well it shot. It was shooting fast, flat, pinging the steel every time. But, I have not put it on paper to how tight the groups are.

Irons or scope?
Yeah, I wish I could do that with irons!
Heck, I can't even get the front sight in focus. That was with a 3-9 accupoint off sandbags.10/7/2011 6:38:20 PM

Heck, I can't even get the front sight in focus. That was with a 3-9 accupoint off sandbags.To get my eyes to focus on the front sight the barrel (& sight radius) would have to be about 5-6 feet long. Reading glasses take some of the blurry out but not all. Old age is not for the timid.
10/7/2011 10:14:30 PM
I'm near sighted so if I take my glasses off, I get a sharp front sight but a very fuzzy target. I wear progressive lenses and I think some where in between might work. I need to get my shooting lenses ground progressive as they are currently bifocal. Yeah, the getting old ride is not one I'd have taken given a choice, but then again, who would?

Just grow old gracefully, adapt and adjust, and quit complaining!
Thats the one thing I wish to keep good on me, is my eyesight. I would rather my back, and bones and everything else go as long as I can see. I would much rather be deaf, then I wouldnt have to hear everyone's bullshit.

your supposed to focus on the front sight with the target fuzzy anyway.
American ballistics M118LR which isent really M118 because they use their own bullet. .75MOA 1.5in group at 200.

Yeah, but you'd still have to read it!

Wish more high end options existed though.

I use that same bullet with Varget for my Coyote loads....fantastic results. Good to see someone else likes this bullet in the AR10 platform.
As far as factory loads mine also prefers Federal 168's with Black Hills running a close second but I get tighter groups with 168gr Amax handloads and Varget powder-sub moa all day long as long as I do my part.
I have just recently started playing around with 178gr Amax handloads with good results so far as well but have not found my pet load for this yet.
11/6/2011 6:03:43 AM
In my carbine so far the German NATO 147 grain stuff is the best. And I compared it to Hornady TAP 168 gn match which was the best in my Rem 700.
11/9/2011 11:58:07 PM
The thing amoung many I like about the AR 10 over my M1A is the ability to add ascope easily and b =e able to see. My eyes are getting hard to focus using irons and the scopes really help. Mine like 168GR the best but does real well with 1502gr. If I have to shoot you some day (Zombe) make sure your wearing a bright colored vest and day glo oragne hat. If I'm shooting my M1A I'll need some help.
With my AR-10 nothing says dead like one to the head.
