You're a better man than me, Gunga Din. 2 MOA ios the best I get with irons and my HK91 and PTR
He does better than I can do with a 4 power scope and PSG1 trigger pack (just shooting Federal AE ball) ;-). I can do ok with an AR but looks like will have to break out the HK91s this year again, toss on a ten power scope after finding what knc1105 was feeding his. Warning evil AR group follows....

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.

I always use the 200 meter setting for 100 yard shooting with iron sigths ... the V notch does work well on the MM53 when it is too dark to really see much of anything, including the target (limited ranges that you can shoot at night ;-).

OK you are getting small enough groups that you need to go to micrometers pretty soon ... You keep posting coated bullets and I am going to have to go back to them (friend got me worried a couple years ago).

Thanks
John

Moly Coating atracts moisture and your barrel can rust under the moly, but Boran Nitride-------DOES NOT-------- go to David Tubbs webite, the world's greatest Rifle shooter is retired now and he's selling all his secrets at David Tubb - Superior Shooting Systems - Tubb 2000 - Final Finish every serious shooter I know is going to Boran. Tubbs is selling a Boran do-it-yourself kit with instuctions and depending on what bullet it does a bunch. Happy Shooting, Ken
