I have a Knight Wolverine with #11 percussion cap ignition. 300 grain XTP's shoot well out of it with 90 grains of 2F, but with the short barrel, the recoil is heavy. Would 80 grains of 2f with 240 grain XTP's make much difference on recoil? Would the 80 grain 2F/240 grain XTP be enough power for deer hunting?
