Ballistic Gel Testing
357 Magnum Gel Testing ProtocolWe tested this Hornady 357 Magnum ammo using a Smith & Wesson 640 revolver with a snub-nose 2.125" barrel. Below, you can see the results of ballistic gel testing, including the raw data from our measurements after firing rounds from 10-feet away. For our testing, we used synthetic "Clear Ballistics" gelatin and a 4-layer barrier to help detect a bullet that might plug and not expand like most shooters would like from a self-defense round.
