A True Doomsday Prepper
My Scenario's === 1) EDC is a pistol with really good defensive ammo (HST) type. 2) Interior home defense = Pistol, same as choice 1. 3) exterior home defense = shotgun, buckshot. 4) close distance 25 yards to 150 yards = AR15 7.62 or a few other calibers. 5) medium range 150 to 300 yards = AR15 223/556 or 6.5 Grendal. 6) long range 300 to 1000 yards = 308, 6.5 Creedmoor. Preferable a bolt action rifle but the AR10 can fill the bill too. Is this list all inclusive, heck no, but should give a direction to head. The point is that many calibers can do the job but there are good / better choices for each situation.
