Last week i shot a 190 pound sow with my Encore, 100 grains of 3F Pinnacle and the 250 grain Shockwave bullet. The bullet hit just behind the diaphragm. The liver and lungs were mush. Judging from the exit hole, the bullet exited in one piece.

Lots of folks make fun of us guys who use the .223/5.56mm rifle on wild hogs. Well, so far this year i've killed over 30 hogs using my AR-15 and CZ 527 rifles. Not one hog has gotten away and only two needed a second shot. i use the US military M193 ball round. That bullet penetrates about 5-6", yaws 90 degrees and fragments,
leaving tremendous damage.
