Recently I've been looking into a flinlock kentucky pistol at a great price and I have never owned a flintlock and never even used one. I know the loading process and all that but I was unsure about a few things. I know that there are different flint sizes but I have know idea which would fit best in a kentucky pistol. Also I've never used a black powder pistol that didn't have a loading lever. So I was wondering what 45 roundball would work well enough (but not so tight I have to hit it with a hammer to start the ball). I apreciate responses and thank you.
