Chris II, your concerns are unfounded. First, I've done a lot of `puter gaming therefore I really know what I'm doing. Second, I'm a graduate, summa cum latte, of Gunshop Commando skul. We learned that a mad minute is the correct response. Inside your house, a free fire zone, you can just spray lead through the walls. I keep an M14 with AP for such occassions in my subdivision.
However, YMMV. For example, as MPFreeman dislikes such a weenie load and keeps 2 BARs in .338WM with Hornady big game bullets for him and his wife. His children 3 and 1 are highly trained as they spend hours at night shooting and learning to duck.
