A while back, our Cowboy Action shooting friends asked if we could make a line
of period correct ammunition. So we grilled the history buffs. Then, carefully fashioned a line of thirteen no-nonsense, period correct calibers and had those shooter friends try them out. Since then, our friends have been plum tickled and forced us to make a bunch more. Though no one ever really had to force us to make more ammunition.
We just come by that naturally.
