Just want to see what you guys suggest for a good HD round in .223/5.56? I have tons of M855 on hand, but hardly what I'd want to fire off in my house should the need arise. "Barrier Penetrator" ammo is hardly ideal for my neighbors, lol. And... noise. With the layout of my house, in a HD situation, I'd likely end up firing from my rather narrow hallway, towards front of house. Being that donning ear protection isn't very likely, and suppressors are not an option, low/minimal noise levels would be ideal. The ears I have are my only pair! So minimal noise, light grain, and soft/hollow-point, any suggestions? Sorry if this should be in caliber corner, it is specifically for my ARs though!
