Hi all - - - I'm the new kid on the block (I use the word "kid" very loosely). This is my first thread, so be gentle. I've been shooting conventional firearms for a very long time, but never got into BP. Many, many years ago my dad and I use to shoot his 1863 Springfield Civil War rifle. I would like to try it out again. It's in very good condition and it just sits in my safe with all the components. Should I shoot it, or am I foolish for messing with a nice antique? I have 4-wing percussion caps and a ton of minnie balls. What kind of BP should I use, and how much of it do I use? Can you suggest a simple powder measure (i.e. a certain cartridge casing)? Thanks for your input.
