12 gauge vs .40 cal vs 5.56 for home defense
Hey forum, I currently have a glock 23 (40 cal) and a remington 870 12 gauge shotgun for home defense. I am getting an AR 15 in the next couple of months rather I use it for home defense or not. I have heard that the 5.56 is actually a better home defense round that the .40 caliber when it comes to over penetration. I guess there is a better chance at the 40 over penetrating. Also with the shotgun, if you use slugs definite over penetration, if you use 00 buckshot, you have to be able to control all of the buckshots, and the ones that do miss will over penetrate a lot. And if you use buckshot, there are a lot of pellets that you have to control, plus they may not penetrate enough. Just wondering because I have a daughter and her room is across from mine. Is all if this true? How do you all feel with the rifle in 5.56 in a home defense rifle. Again I ALREADY HAVE A 12 GAUGE AND WILL GET THE AR RATHER I USE IT FOR HD OR NOT. thanks a lot, you guys are very helpful to a novice like myself.
