Froze my fingers off but I was able to shoot 3 of them at 50 yards in my traditions hawken woodsman flintlock with 90gr 2fg olde eynsford and that puny 63gr bullet. Felt like a .22 but with a whole lot of nads behind it LOL.

Under 3/4" at 50 yards, so thats perfect. They are shooting 3" high, same with round balls, but most likely way to high to hit a target at 100 yards.

If I get a day with no wind, I just might zero in that flintlock with these and have some fun and see how they do.
