Tell me true Bulls-I_24, is your barrel a chrome lined 1/9 twist? If not then what? I have a CMMG insert and had trouble with it in a couple other type barrels. They were un-lined though.

Yes it is. Have you tried the heavier 40 grain? The newer gen kits are supposed to cycle subs, I will be trying the CCI subs I have tomorrow, 1050fps 40gr. I would like to try some 60gr subs but dont have any. The 20in 1/12 barrels should group the best but I don't have one to test that theory. What yardage where you sighted at and what distances did you shoot? I think being sighted in at the calibers maximum point blank range would help. Does chrome lined help with accuracy? I thought it was for corrosion resistance? This spring I will definately post some 100yd groups.
