Didn't read all of the responses, but i live in TX all my life, I have hunted hogs on my property with an AR-15 5.56 behind the ear drop and no sound. I know people will come up with reasons to use bigger, I have a 6.5 Grendel that I use now, but it is all about shot placement. If you plan to shoot them in the shoulder, carry your 6.5 Creed, matter of fact if that is all you are shooting, then that is what I would take. They are not King Kong like some want to believe, I have killed them with 22 LR as well, all roads lead back to shot placement, and that is for anything.
