I hunt hogs all year,but when it' hot I slow down some,unless someone just wants them killed off there place.I've used the .270,30-30,303,.300mag,.44mag,22LR,and my bow.Shooting through the armor on a big boar can be a little tricky,but a fairly heavy well constructed bullet should work ok.Light high speed stuff may not penetrate that armor.I've killed big hogs that had bullets and buck shot embedded in the rib cage.Big boars can be hard to bring down,so it's best to be prepared for follow up shots,especially if your hunting on the ground.Hogs are usually in a group and when you fire at them ,they will go everywhere.If you're pretty good you may get 2or 3 out of a bunch.I got 3 one time with a Marlin 30-30,with 5 shots,the first one at about 30 yards ,the last one at 5.I like to hunt in the evening,but sometimes they will go nocturnal.It's true a lot of people make money on there hogs,but I know a lot of them that just want then gone,period.Thats where I hunt.Good luck with your hunt frosty and you to gunner.
