I'm trying to figure out what ammo would be best (overall) to load my magazines, purchase a case of it, and practice with the remainder.
Scenario:
You have your AR15 ready for a SHTF/The Collapse/EOW (or whatever). You may have to 'bug out' or stay and defend your turf. What ammo have you preloaded your AR15 magazines with and why.
Thanks for your input.
