A .22 Beeman Crow Magnum 18.21 grain hollow point fired into home made ballistic gel. Muzzle velocity was way too fast at around 1150 fps. It certainly did not tumble but it was fired at only 15 yards. It almost turned inside out!
These are empty 9 mm and 45 ACP cartridge cases after an artistic makeover with a .177 pellet at 30 yards. They are like snowflakes. No two are identical. Each one is a unique creation.
