Firearm Basics - Bullets and Grain Weight

This video tests the penetration capabilities of various calibers against a boulder, culminating with the .50 BMG. While smaller calibers like .22 LR, 9mm, and .45 ACP caused minimal damage, larger rounds like 5.56mm and 12 gauge slugs began to chip the rock. The .308 and initial .50 BMG shots caused significant fragmentation but did not penetrate. A second .50 BMG shot successfully penetrated the boulder.

This video investigates the common belief that .22LR bullets 'bounce around' inside a target, causing more damage than larger calibers. Through high-speed footage of ballistic tests on pork shoulder, the presenter compares .22LR (CCI subsonic and Mini Mag) with 9mm hollow point, 5.56x45mm FMJ, and 00 buckshot. The tests suggest that while .22LR may not always exit, it doesn't exhibit significant ricocheting or tumbling behavior within the medium, unlike some larger calibers which show more energy transfer and fragmentation.

This video from GFG discusses the significant drop in ammunition prices for eight specific calibers, with some approaching pre-2020 levels.
