OK guys looking for some info. I've been shooting my new to me T/C pa hunter carbine lately and I'm burning thru patches is this normal.I use 60 gr. of 3f,.010 patch .490 rd ball. THe part of the patch behind ball is still hanging on by a 1/8" of material on one side only. Been shootin black powder for some years now, always use my fast twist with sabots, first time playing around with round balls. By the way the gun is shooting very good at 50 yd's.
