Ponta Oca vs Lago de Argila: O que acontece nesse desafio incrível?

This video demonstrates a DIY method for creating hollow point projectiles by modifying FMJ bullets using a Ryobi drill. The creator, identified as an experienced individual with expertise in ammunition types and reloading, tests the terminal ballistics of these homemade hollow points against standard FMJs in a clay lake. The results show a significantly larger cavity created by the DIY hollow points, leading to a discussion about potential accuracy testing for these modified rounds.

This 'Smyth Busters' episode from Brownells Gun Techs debunks the myth that shooting jacketed ammunition can effectively clean lead fouling from a firearm's barrel. While FMJ rounds might remove loose powder and lube residue, they tend to smear lead deeper into the rifling. The video emphasizes that proper lead removal requires dedicated bore solvents, cleaning rods, and manual effort. It also briefly mentions a specific recommendation for AR-15 owners using .22 LR rimfire conversions.

This video explores the theoretical and practical outcome of loading a 50 BMG cartridge into a 12 gauge flare gun. The experiment, conducted by a hobbyist, demonstrates that while the 50 BMG cartridge surprisingly fits, the flare gun's firing mechanism and primer strength are insufficient to ignite it. The test highlights the significant differences in primer resistance between ammunition types.

This video debunks the myth that shooting upwards is safe, explaining the lethal terminal velocity of falling projectiles. It showcases the Canik Mete MC9 Prime with a Gideon Valor optic and demonstrates the use of 9mm shot shells for controlled, less dangerous demonstrations, highlighting their unique projectile dispersal.

This video debunks the myth that a .50 BMG round passing near a target can be lethal due to shockwave. Using a ballistic mannequin head and a Big Kahuna Firearms Raptor-50 rifle, the test demonstrated that while the .50 BMG round impacted and destroyed a concrete block behind the target, it did not affect the mannequin or the cardboard placed near it. The conclusion is that a near miss from a .50 BMG is not fatal.

This video conducts a destructive test comparing the impact of .22 LR and .50 BMG rounds on a ballistic head model. The .22 LR caused minimal damage, while the .50 BMG completely destroyed the head, highlighting the vast difference in energy and destructive potential between the two calibers. The test also showcases the Raptor .50 BMG upper receiver as an accessible way to experience .50 BMG ballistics on an AR-15 platform.
