I will probably get a pump shotgun with an 18" barrel for home defense and get a second, longer barrel for skeet shooting.
My friend suggested a 20 gauge, mostly for my wife's sake.
I watched a video
https://www.youtube.com/watch?v=ElFmPZMtaSIwhere a tester looked at how much penetration of a wall would occur for different types of shot.
The shot with a wide spread and some but not full penetration of the "wall" was....
Winchester Super-X (2 3/4" #2 drylok steel)
Winchester Xpert Hi-Vel (2 3/4" #3 steel and #4 steel)
I think this means this would be good defensive shot for home defense, if wall penetration was to be avoided.
Is this skeet shot? Sorry I don't know anything about this stuff.
