Ever have one that drives you to the point that you look at trees and think about how hard you could swing it? Well found it. Bore .580 cast mines out of a lee mike .577 use 3f and 2f from 35gr to 65gr lube with spg bore butter and about every thing I can think of. Lead, soft use the same for round ball in my .50 now the fun part, with .570 round ball and .015 patch at 50 yards just about one hole! The minies I sometimes hit the target if I'm lucky. First time I have ran into a rifle that I could not get to shoot. Run out of things to try with this one!
Bore good
Minie is very good push fit
Powder from 35 to 65gr
Lube every thing I can think of
Lead soft
So, can anyone think of something that I can try? Or is this going to be the one that got me.
