Shooting Hollowpoints Thru a Car Door - TheFireArmGuy
This test evaluates the penetration capabilities of various hollowpoint handgun calibers (.22 LR, 9mm, .40 S&W, .45 ACP) through a car door with plywood backing. Most calibers, including .22 LR, 9mm, and .40 S&W, consistently penetrated both materials. The .45 ACP showed varied results, with one round expanding significantly upon hitting the door and failing to penetrate the plywood, while others passed through.
