In this video, I test four of the most popular bear defense calibers to see how they perform in a real penetration test. I start with the Glock 20 Gen 5 chambered in 10mm, followed by the Smith & Wesson Model 66 in .357 Magnum loaded with DoubleTap hardcast ammo, and the ultra-light Smith & Wesson 329PD chambered in .44 Magnum, also using DoubleTap hardcast. I also test 12-gauge slugs for comparison. You’ll see these calibers fired into a block of paper and a Level IV ceramic body armor plate from RTS Tactical to see what penetrates and how each performs. I use the Garmin Xero C1 Pro chronograph to record real velocity data, and everything is captured in slow motion so you can clearly see the impact and recoil differences. I also discuss bear spray vs firearm options for bear defense. This is a real-world bear defense caliber test comparing 10mm vs .357 Magnum vs .44 Magnum vs 12GA slugs. http://mrmadness.co Check out this profile on Campsite.bio! https://campsite.bio/mr.madness AR-15 10.5” vs Tavor Bullpup 5.56 NATO: Which is Better? • AR-15 10.5” vs Tavor Bullpup 5.56 NATO: Wh… 22LR vs 9mm vs 10mm vs 5.56 – Ice Test • 22LR vs 9mm vs 10mm vs 5.56 – Ice Test
