On my last feral hog hunt, I used my favorite caliber, a 375 H&H. Loaded with 235 grain partitions, it does an admirable job on North American game.
With the 300 grain Barnes solids and 300 grain Partitions, I get the same point of impact. Devastating on dangerous game.
Do you harvest the meat or are you just doing pest control on gristly old boars? If your answer is yes you know what my next question is going to be...
(Fun to be talking about this stuff for a change instead of the primaries...)
One of my my most interesting hunting moments ever, was a 225 lb. ragged tusked booger charging me in a Pine Break Thank God I got him in between the eyes at 20 yards. My hand was shaking afterwards.
