Hollow point vs full metal jacket penetration test
This video demonstrates a penetration test comparing hollow point (HP) and full metal jacket (FMJ) .45 ACP rounds fired from a Rock Island Armory 1911. The test uses multiple sheets of drywall as a medium. Contrary to common expectations, the hollow point round exhibited greater penetration than the FMJ round in this specific experimental setup. The host, a firearms enthusiast, invites viewer input on the unexpected outcome.
