Ok; lets talk .45 roundball for deer. I want to build a rifle from a kit and I am thinking about a .45 caliber. Everyone seems to talk about the .54 but I would like to hear from the people who use the .45 with patched ball for deer. I am thinking along the lines of a 42" long 13/16" barrel but swamped would be ok with a pre-carved. How about twist 1/60 or 1/48?
