Hey Bird Dog, I am glad you were not seriously hurt. I had a couple close calls a few times in my rabbit and bird hunting days, not by my hunting buddies but from others hunting on public land.
I've used my shotguns in IDPA and action shoots, and at what I consider self defense ranges, I am comfortable with what I use.
Others experiences will vary. I am glad we live in America, land of the sort of free.
