I figured I'd make a separate post about this so it doesn't get buried. If you guys want the chance to shoot some sub-MOA groups and don't hand-load, bite the bullet and get some Federal Gold Medal Match 168. The gun has a tight twist with 1:10 so heavier bullets will likely shoot well, who knows, maybe a heavier GMM at 175 grain might even do better. Another poster has run GMM 168 as well and had great results, all sub-MOA.

Gun has had approx 300 rounds through it until tonight, all milsurp Hirtenberger 147 from an IMI mag. I may also have the first confirmed BCL 102 kills as two nuisance beavers met their end tonight before I set up my half assed range :) . The gun has shot well and the only issue thus far was a failure to feed the poly tipped Hornady A-Max, but I believe that was because the mag wasn't fully buried.

I was a bit rushed before dark so it was quick 3 round groups, ya I know I should be shooting 5's and I will update when I do. The Hornady group was done by my dad and he said he wasn't 100% confident in his trigger pulls, it was low light even with the 50mm objective and his eyesight isn't the best. I am also a novice to mediocre shooter but I was pretty confident in my pulls with the GMM... the Hirtenberger I have shot better.

When you take the distance into account (120 yards) and the centers were a index finger width, the gun shot the GMM about 0.5 MOA. This is early days and it's possible the group would open up or I lucked out, but all these rounds were fired within a minute of each other with no barrel cool down. I'm cautiously optimistic and saying is the gun has some serious potential with good ammunition. Keep in mind that shooting sub-MOA with over the counter ammo in an AR10 is no "given", watch Nutnfancy put DPMS and Armalite pattern 308's through their paces and when you take into account this gun is very reasonably priced, I have to say I'm tickled with it so far.

Range conditions - 16 Celsius, Windspeed - 0-5 kph

Distance - 120 yards

Right now gun just has a Lantac Dragon brake, Geissele Super Charging Handle, Magpul Moe + Grip, Zeiss 4-12x50 and a Vortex Mount.

Looks great. Mine is finally in the mail and I have some GMM to try. Most likely will be handloading with 185 berger vld's for hunting though. If they do well
 
So Federal Gold Medal Match?

hmmmmmmmm.......


168gr Sierra Matchking
Federal Brass
42.8gr IMR 4064
COL 2.800

:)
 
So a .308 semi that doesn't require special reloads to get MOA. Man I thought that was impossible according to some on here :)

Now if NEA could hurry up and get IOP sorted out ;)
 
Looking good so far but a single 3 round group is hardly an indication of any type of consistency.
I'm looking forward to getting my hands on one of these and running a few mags through it.

Keep the range reports coming, looks like it has the potential to be a great rifle as long as you don't get one of the Friday guns.

:cheers:

I have to agree. I had my 150gr handloads do that with 3 rounds multiple times but the 4th and 5th decided to go elsewhere and opened up the group. That being said, at 120 yards that is good shooting, great job OP!
 
Any updates on .308 surplus running through these rifles. Any "serious" concerns by owners.

I have run Hirtenbgerger and Norinco through mine. It will run both, but for some reason the combination of the XCR-M pistol mags and the Norinco do not like eachother. Norinco ran perfect in the IMI mag the rifle was supplied with. Hirtenberger ran without issue.

As far as groups, somehow I forgot to do the Hirtenberger, but norinco did this:

I shot 4, 3 round groups with GMM and all we 1MOA - I did fire one 6 round group and 5 were 1MOA but 6th went to 2. Could that have been me, absolutely. I am happy to see two guns that both like the match kings maybe more can confirm if that is a good factory load for gun in general, but I know it works for mine.
