I'm new to AR's, just got my first just over a month ago. I've seen several threads about the need to stockpile ammo in case of a SHTF situation or I guess in case they try to outlaw the manufacture of the stuff. (These are my perceptions as to "why" anyway.) So when you guys are stockpiling, what are you primarily focusing on? Are you stockpiling a bunch of the cheaper stuff you would normally shoot at the range or are you buying a bunch of defensive ammo stuff? I'm on a limited budget since I just got an AR and an optic so I won't be buying any cases anytime soon. In fact, right now I have trouble keeping up with the amount I shoot. I have one 20-rd box of defensive ammo that was pretty expensive. What do you suggest for me? Should I slowly buy an extra box of just regular range ammo and put it back or should I be focused on putting back boxes of defensive ammo? Also, what about mags? What is a realistic minimum you'd be comfortable with? (I have four P-mags.) TIA for your suggestions!
