Probably the same thing would happen here and makes me want to check into armor piercing 12-gauge rounds. This stuff really makes my blood boil.
get a pistol in 762x25. I tested them, 45, 38, 357 and 9mm on an old 80’s vintage flak vest. The only ones that went through were the 762x25’s. Not sure what they would do on a more modern system of soft body armor.
