I've read countless times over the years about slugging a barrel (bore) to get exact dimensions so I think I'm going to give it a go.
I have a lot of "pure" lead (I've yet to test it's hardness but it "feels" to be almost dead soft), so where do I go from here?
I have 38 and 9mm and 44 and 45 caliber to slug (in handgun), I also have several rifles I'd like to try as well.
Looking forward to your input from personal experience.
