.380 ACP Hollow Point Expansion - TheFireArmGuy
This video demonstrates the expansion of Remington Golden Saber .380 ACP 102-grain brass jacketed hollow-point ammunition when fired into water. The test, conducted using a CCW 380 pistol, shows significant expansion, with the bullet diameter increasing from approximately 0.25 inches to over 0.5 inches, exhibiting a starlike mushrooming effect. The instructor notes this provides an idea of the bullet's terminal performance, though acknowledges water is not a perfect substitute for soft tissue.
