This stalking rifle in 11 mm has .454 grooves and .433 lands. Every bullet, I think it won’t fill up the bore or too small for case. Some are too big for case. I could PP to groove size but still too big for the brass.
What would you do? Can one PP to less than groove? Should I use a jacketed bullet at .446 or .435. Will a .446 lead boolit do leading? All w/ BP of course. [smilie=b:
