Let's say you're moving in a week to an extended stay hotel in another State. You will bring a 1911 for lawful personal protection. You know the 1911 feeds your FMJ ammo fine. You've never tested the other JHP ammo you have through the pistol, and you won't have time to test before you move. The 1911 is a reliable pistol and has never jammed through hundreds of rounds of FMJ.
Would you load it with the FMJ, or with the expensive (but untested) JHP?
