I know there is a lot of differing opinions about mechanical broadheads, but I hunt hogs in Texas with mechanical broadheads and I have had excellent success with 3 blade rage broadheads. I have shot smaller hogs (80 lb range) that I could see daylight through the pigs when they are hanging from the gambrel before the hide has been removed. I have killed large hogs with them as well, but on large dominant boars, it is best to shoot them quartering away for better penetration so you don't hit the shield. I killed a 281 lb boar that had a fixed blade slick trick broadhead stick just inside his shield and healed over. I shot him quartering away with a 3 blade rage and he ran about 40 yards and piled up. The only thing about mechanical rage broadheads for hogs or deer is that you get 1 animal before you have to trash or rebuild the broadhead. I am a skeptic about their new kore broadheads though because of surface area I think penetration will be an issue for hogs. I would also stay away from 2 blade mechanicals for large pigs, because a slit closes up much easier than a hole. You may get penetration, but the thick shield will seal right back up and if the arrow does not get a complete pass through a blood trail will be a rumor. I think the whole principle behind the schwackers is a joke. No entrance wound, the blade deploys once the broadhead is inside the animal. The vitals of an animal are soft you don't need the blades to be scalpel sharp once they have passed through the rib cage and rough cuts don't seal and clot as fast or easily as sharp cut wounds.
