Just last week i was at the range and bought three boxes of 180 grain full metal jacket .40 caliber ammunition. It was the cheapest stuff there but wow did it numb my hand. It must be loaded very hot because by the time i was done with all 150 rounds my hand hurt and the web between my thumb and forefinger hurt like you wouldnt believe. Nothing else that i have shot through my Glock 22 was like this. Anybody know anything about this ammunition?
