Hawgs come in all sizes .I once used my .50 backed by 80 grs of 3f .
Also used a minie rifle. Now I use either a .62 rifle with a hardened ball or a 54.
I refused a shot at a 400 lbs monster sow one night .Not that I didn't think it wouldn't die, but that I might ,in the interval between the shot and by the time the shot had it's fatal effect because I was only ,maybe 20 yds away .The nineteen eleven I had as a back up wasn't going to cut it either.I had a ''revelation'' then and there carefully backing out of the pencil cactus .In retrospect ,Brave Sir Robin must have known his limits as well .
I ''up armed'' and later that night I did get her from about 60 yds away ,big trees between us . The gristle shield was three inches thick. Most hogs aren't that big or that tough . But you just don't know what you are going to come across.
Just use a little common sense based on where you find yourself .A stoutly loaded hogleg in meaningful caliber is helpful as well .
