Re: Allen Mag Shooters Group
Thanks Bob, I noticed the same thing on the round count. One good thing about the barrel is that it cleans up really quickly. Using Montana Extreme Copper Killer and Hoppes Elite, nylon brush and nickel plated jags.
This is close to the upper limit, sometimes I was getting a hint of drag on the base of the shell with 110g of powder and temps in the upper 80's with everything in the shade. Going from 110g to 111g only increased velocity by 20 fps, not the usual 50 fps that I was seeing with 1.0g increase in powder.
