10mm Hardcast!
This video from Autumn's Armory tests the penetration capabilities of 10mm hardcast ammunition against various barriers. The presenter, an enthusiast of powerful handguns, uses a Ruger 10mm 1911 to shoot Underwood 220-grain hardcast bullets through plywood and water jugs, comparing its performance to 9mm ammunition. The experiment aims to determine how much material the 10mm hardcast round can penetrate and if it can be recovered.
