You have to understand Keg, that I am a pig killer, not so much a hog hunter..... My goal is to kill economically with no collateral damage. I have many times, shot pigs within feet of cows. I once shot under a cow to get to a pig. I will not attempt this with a .30 cal lol. Traps are great ballistic testing centers. I've even seen 45colt punch out of a pig.
Open, long or safe shots on larger pigs, specially in the east, or swamps, the bigger the better I say. West Texas rolling plains pigs ain't so tough.
