10mm Hornady Custom 180 gr XTP fired from 4.5" barrel EAA Witness through four layers of denim into calibrated gelatin.

BB: 600.4 fps, 3.7"

Impact velocity: 1,261 fps
Penetration: 15.9"
Retained weight: 176.8 gr
Max expansion: 0.761"
Min expansion: 0.583"

Sorry, but I experienced an operator induced malfunction on one camera and missed the side shot of the gelatin.




Okay, in all seriousness, that really isn't a fair comparison. Sure it's the same bullet weight and sure it's almost the same barrel length but we don't measure revolvers the way we do autos. It's also a VERY heavy weight for .357, while it's middle of the road for 10mm. The .357 load was probably intended for use in a much longer barrel. I intended to test it in my wife's .357 Rossi M92 but I only had two rounds and the first exited the side of the block.

Bonus happy fun time with Desert Eagle, levers, and a 37mm:
