I dont know if yall have big hogs where yall live, but I am 57, hardly need a lesson on what caliber I need for a big hog. I run cattle on 3 pastures, average acreage of 600 plus on each, I kill more hogs in one week than most of these people on this site will kill in a year. I have rifles from .17hmr to 30-06 but largest calibers I use are 6.5 Swede, 7-08 and .308. I always carry at least a .44 mag or .45 colt with 300 gr. cast bullets. I use the .17 cause a head shot or even a lung shot will make jello of their organs, dont care if they drop, run a mile or not, my pastures are hell to shred, cut hay on bale hay etc. if I were to shoot pigs with centerfire ammo, I would go broke, have killed big boars with the 17, wish I could post but at my age, computor illiterate.if you get a chance to actually see a big pig try the .17. you can check out
www.texasboars.com to see the size hogs we got down here and the .17 will do it, I dont mess with the, they are good buzzard food and coyote bait. my donkeys run the coyotes off. I dont know what hunting is like in Wisconsin, but here in Central Texas I have know what I can do for over 45 years, like I said dont need no lessons. Irresponsible, you pay the bill to farm your land and tellme it is irresponnsible... they are like vermin, rats to me. 39 years ago, qualified marksman, designated rifleman in the military, dont think you can teach me much.
