47 rounds to bust through it
It was easy and quick shipping and I only got it to shoot the plate. Took 12 rounds of 9mm , 7 rounds off .38spc, 12 rounds of 223 , 10 rounds of .300blk and 6 rounds of 7.62x39. 47 rounds in total before breaking through on 762. Pretty impressive might not be NIJ certified but you will live if you take a round or two.
