"Excessive Penetration!" If you want to do some tests! make you about four square 2X4 frames about 2 ft. square. Find some old drywall from a contractor or dump and tac it onto both sides of the frames. Then get two 8 ft. 2x4s and attach the frames spaced out about two feet apart by nailing the 2x4s across the top of the frames just to hold them together for the test. And stand about 10-15 ft from the first frame (which would represent the average distance of confrontation in a home) and fire the slug through them. I think you will be amazed at the penetration you get. I would certainly recomend smaller projectiles in a home if you have anyone living there other than you and or your wife. You might want to think about for example #2 Shot Mag Loads. First of all at close range the #2 Shot will not even leave the wad. If you would shoot one at a paper target at 3-5 yards for example you will probably have one large hole in the target as the wad with the shot in it will be together and go through the paper. It will look like a slug hole! Only some thoughts! But upon impact with barrier material the #2 shot will start loosing momentum! Therefore less penetration through additional walls and material. But still plenty enough to bring an aggressor down with no doubt with a good shot! Only some thoughts!
