Guys if you can shoot 2 MOA with irons, when they start choosing teams I want you on mine. Two tricks that I did on my irons was I took a good precision file and narrowed my front sight to around .050 and skipped the V-Notch 100 yd setting and sighted in 2" high at 100 yards and used the 200-meter/yard setting. It fits the front ring perfectly and your group size will drop in half immediately. If you're shooting 2-MOA with that huge 100 meter V-Notch you are a Bad***. I have Bill Springfield triggers in everything, you can't shoot well with a twelve lb trigger. Both of them have been fire-lapped, and in a lead sled not bags and a indoor range with no wind, as close to laboratory conditions as you can get. Those were my AR-10 Match handloads but Privi shoots very well too. The PTR-G.I. shot .942" with Privi. The hand load is Boran Nitride coated which reduces friction, barrel wear and chamber pressure so I won't post the charge because if someone used that with a "NAKED" uncoated bullet it might be too hot. It's Lake City Match brass, uniformed flash hole CCI Bench Rest primer, Varget powder, Sierra 155 gr Palma Match King Boran coated, Lee factory crimped and muzzle velocity of 2,670 fps at 850 ft elevation. But if ya'll are posting AR groups,------------I'll Play--------This is my favorite AR with it's baby bullet, after I fire-lapped it and put on a Miculek Muzzle brake. POI was low before sight-in, but look at the group. I would not trade a truckload of them for my HK-91, I can't explain it, they are addicting, I don't do drugs but HK's have to be worse than drugs.
