Will be trying this powder out of a ruger target model with 26" heavy barrel with 53g vmaxs real soon.
I have 40g, 50g, and 53g vmaxs, as well as some 52g amaxs and 52g SMKs.
It puts 5 shots under 1/2 MOA with 40g vmaxs and 28g benchmark at 3800fps, and 52g AMAXs with 26g benchmark at 3400fps.
Sounds like a good powder and since im about out of benchmark and cant find any, this was sitting on the shelf.
