Home Forums Hunting & Shooting Muzzleloaders Getting the old timer out of mothballs

I shoot 90grn fff and the round balls out of my TC Renegade. I have tried sabots and powerbelts, but they are erratic. I have not tried maxi-balls of any sort in over 15 years. Simple patch with bore butter. The roundballs are consistent and even on the 3rd round without cleaning out the bore.
