I stocked up 1k rounds of FMJ just so there's some reserve while I slowly stock up JHP defensive ammo. I see no reason why all your reserve ammo shouldn't be defensive ammo. If the idea is that in a SHTF situation you need the ammo for defense, it should probably all be defensive ammo. Only reason to have any FMJ is to keep the total where you want it while you stock up the good stuff. Every time I buy another 100 rounds of JHP I move 100 rounds of FMJ to my "to-be-shot-at-the-range" pile. Ideally I want to eventually get to 1000 rounds of premium defense ammo.
