Re: Remington UMC ammo
I would use them for defense if...
I got 300 rounds off without a single misfire or misfeed.
The primary difference between defense rounds and plinking (aside from the bullets used) is quality control. Every time I pull the trigger on a defense round it had better go bang. If not then I'll be on the phone right off of the bat, and I will never by that brand again. It's not necessarily the case with plinking stuff. If I get one misfire out of 100 with the plinkers I'm ok with that, more than that and I would be on the phone with the manufacturers trying to figure out whats wrong.
I load most of my ammo, but (currently) not my defense rounds. That's mostly due to the whole lawyer making me a monster thing.
