RE: Slug guns...Hear the bullet hit?
I have never heard the slug hit with a shotgun or muzzle loader because the bullet is still moving to fast at the ranges I hunt. I have heard it quite a bit with .22 rimfires though. And with good follow through I can see the bullet in my scope with target loads. Same thing with my bow, I can watch the arrow go all the way to the target.
Never seen a vapor trial from a bullet though.
