these were originally made for the massachusetts muzzleloader season
i use a 535 round ball with an 015 patch
it shoots wicked good at 50 yds.
dont try to shoot round balls any larger than 535 or you should
bring a sledge hammer to ram the ball down
killed my first deer with a 56
good shot, out of a tree stand,, deer was right under me
about a five yard shot!!!!
