Figured some here may be interested in this site. Lots of various firearms & rounds tested against a variety of targets. Rifles & handguns vs Locks, bullet resistant glass, sand, insulated walls, lvl 3A body armor. Saltrock in shotguns, cowboy guns, lots of types of ammo, etc, etc are all tested.

Good stuff. Enjoy!
