I'm am adding a mini 14 to the safe for HD duty. It will be a back up to my semi auto 20 gauge. I know Nothing about 223/5.56 ballistics. What type of bullet am I looking for? Over penetration is a concern as I live in a subdivision with homes on a bit less than 1/4 acre lots.
I see bullet weights from 55 grain to 77 grain. I'm assuming I want a lighter frangible bullet to lessen penetration of the sheet rock / stucco homes in my subdivision. Any recommendations on bullet types or manufactures would be appreciated. Thanks.
