Been reading and searching A Lot.
I have a new model Winchester Miroku 1894 Sporter. It has a 24” barrel and 1:15” twist. Recently with another powder, it clocked 200fps faster with beginning loads than the 30” test barrel used by Lyman.
I’m targeting 1400-1600 fps per my reading for a good hunting load.
My question is: How lo have you loaded IMR-4198 in a 38-55 with a 250-255 gr cast boolit?
