if you really want to hog hunt leave the guns at home get a few good dogs.
Let the dog's pin it down and you go in there with just a knife and finish the hog off.
I've done it ONCE and let me tell you........You have to be a absolute IDIOT to do this, But I was goated into it as my manhood was questioned and Y'all know me. I had to be THAT IDIOT.
I prefer my 30-06 and shoot them at 50 yrds or better, they can and will turn and try to eat your lunch, A buddy shot one at 30yrds and got a 10" scar and 25 stitches to show for it.
