AIM is advertising this ammo, thought it might be of interest to some of you. I never saw a .380(9x17) bullet that light, perhaps a typo. No picture of the box came up.
“New Russian manufactured .380acp (9X17) ammunition. Features a 50grn lead core full bi-metal jacketed bullet, copper washed steel case, and non-corrosive berdan primer. Packaged 35rds to a box. While supplies last.”
