Lotsa, I settled on 3500+ (don't have my notes here) with a 55 gr NBT and under MOA accuracy with my Kimber Montana in 223AI (factory punched tube). I bested my TAC load in vanilla 223/5.56 by 50-100 fps with 55's and 77's.
I sold the rifle to a good friend of mine and he used my data and was within single digits on his chronograph. I have a 204 Ruger and a 22-250AI both in Montana's and didn't really need the 223 so I let him have it and really kinda regret the sale but it went to a good home. I also let him have my supply of Lever and figured I'd burn through the 2 jugs of TAC I had then make the switch for good, one jug of TAC left...
So did you use it in an AR or not?...........can't clearly decipher whether you did or not from the above.
If so, how was functioning, gassing, ejection, brass, etc. What were your loads?
