Remington Ultimate Muzzleloader & 250grain Hornady Muzzleloading SST Bullets pushed by 200 grains of Triple Seven pellets.
Shot was ~50 yards with complete pass through. He ran about 10 yards, spraying blood out of both sides, before a rather dramatic face dive (9.5 / 10
).
Dead on his feet at the shot, just didn't quite know it yet.
