Just finished prepping 500 pieces of 223 brass and looking for recommendations as to which bullets would be best for home defense should I decide to use an AR-15 for this purpose (currently a 40 cal. handgun and 12 Ga. pump shotgun back up my 2 dogs). My main concern would be shooting through a window or door and accidentally hitting a neighbor as houses are pretty close. The exterior of my house is brick so I'm guessing it would stop ballistic tips. Any suggestions would be appreciated. Thanks.
