I have to pass this along for folks wondering about the abilities of a traditional muzzleloader with plain old lead bullets.
My hunting pardner popped a nice 3-point at a measured 55 yards on Kodiak today using his 50 cal with 90 grains Pyrodex P and a Maxiball. Hit it head-on just off center in the brisket. The Maxi passed through the top of the heart, clipped both lungs, shattered the liver, passed through the stomach and intestines, entered the front of the right ham, passed all the way through that while missing the bone, then lodged under the hide. It staggered back when hit, then traveled about 15 feet before piling up.
No wonder I haven't recovered any! Conservative estimate is that the Maxi passed through 4 feet of animal before stopping. No major bones after the brisket, but judging by the state of the liver, it had lots of jeewhiz going for it.
I'd have no qualms using this combo on lots bigger game.
