Hi guys I want to start pig hunting, I have a 7mm mag but I'm not sure what grain to use. I've read that you don't want a bullet that fragments because it can ruin more meat than necessary. I've read guys taking them with a variety of grains and it seems the guys using a lighter round are making head shots. I'm not looking to go trophy hunting I'm looking to shoot them for the freezer. I currently have Winchester super x power core 95/5 in 140 grain. Would that be suitable?
