I shoot them in the shoulders too. I use 25 06 and up. I have shot quite a few with an AR. The 52 grain Barnes will go through both shoulders. I have trap gates on 3 feeder pens, so I catch quite a few. Pigs are good shooting practice and good to test bullets on. Shooting pigs convinced me Berger VLD bullets weren't all that great, but that's just my opinion.
