So many defensive ammo come in 20-25 rounds and more than a buck a round sometimes upwards of 2$ or more. I came across some Black Hills 357 magnum 125 grain stuff that's a hair under 1$ per round, comes in boxes of 50 and can be bought in bulk up to 500. Anyone used these guys ammo before and have thoughts, particularly their 357 magnum 125 grain jacketed hollows?
