I had the thread up slugging a barrel, and you guys steered me in the right direction. But I have just one more question, since I didn’t know the real bore diameter of my Marlin but now I do, it’s 0.4305. I’ve been sizing my boolits to 0.434, is that too big? Would I be better off sizing the boolits to 0.433? I’m useing a Lyman #2 ally, and shooting very mild( under 1000 fps) loads.
Thanks
Paul
