As of yet, I have had no issues with the matchkings not doing well on the critters. However, I would recomend that with GHogs and things of that size, 150yds minimum with the SMKs. with the 1gal plastic milk jugs filled with water, I was drilling 7mm entry AND 7mm exit holes. at 200yds and beyond, I get nice explosions. Not quite as dramatic as the SSTs, Vmaxs, or SBTs, but substantial enough for massive tissue disruption. I would think that with the bigger game animals, a shot right through the shoulder blade at a couple hundred yards with an SMK would result in immediate fragmentation. I know some folks are going to flame my a$$ for promoting SMKs for hunting, but the results for me so far have been quick kills.
