BEST Bear Defense Caliber? 10mm vs .357 vs .44 vs 12GA
This video conducts a penetration test comparing 10mm, .357 Magnum, .44 Magnum, and 12 Gauge for bear defense scenarios. It includes velocity testing with a chronograph and tests against paper blocks and a Level IV ceramic armor plate. While some rounds penetrated paper, the Level IV plate remained largely intact, with minor cosmetic damage after multiple impacts, including a concentrated 10mm assault.
