Thanks, what's your coal?11.8 of 1680 was giving me 1000fps with an 8” barrel and the berrys 220. Roughly the same with the 220smk’s iirc. I would start in the low 12s and work down.
I would have to look it up to be certain, but berrys list it at 2.15. I’m sure it was around there.Thanks, what's your coal?
