What are you trying to accomplish with changing powders? Faster velocity, more accuracy, cleaner burn, etc.?
I've been using 26.2 gr of RL-15 behind a 75 AMAX. This out of a 22" Rock 5R barrel (1/8 twist) and it gives me 2950 fps with LC brass. I know I might could hit another gear but am happy with it based on our temp swings.
I have been happy with RL-15, 20"rock creek 5R 1/8 twist barrel.Im just curious what other powders are being used.It seems like so many shooters are using varget.
Hey Stick, LeveRevolution, right? I have a .223AI, I have been running Varget 26.2 grains out of a 22 inch tube. 80 grain Amaxes. Getting 2830 fps. What speed can I safely get with Lever and about what charge?
