Just got back from my hog hunt. Took my ( first time out with a muzzleloader) Wolf 50cal, 348gr HP Powerbelt bullet, 100gr of Pyrodex pellets, and Winchester 209 primer. Had a 30yrd shot and she dropped like a sack of flour. My shot (I was trying for the head ) hit her in the upper left shoulder near the jaw, so I hit alot of bone. I was able to find the bullet, and (frontier gander) it looked just like the bullet in the middle of your second set of photos you sent. The sow dressed out at round 225 so I'm pleased as heck. Probably will go with the aerotip platinum 225 gr. bullets for my Colorado deer hunt in Sept. Cheers.
