Ponta Macia ou FMJ: Qual é Melhor?

This video from Civilian Tactical explores the relationship between sound and terminal ballistics. The host demonstrates that while a suppressed .38 Special round is significantly quieter, a supersonic .357 Magnum round, even when suppressed, produces a much larger wound cavity and greater overall damage to a target. The expert assessment highlights the host's high authority and clear understanding of ballistics.

This video demonstrates a practical, albeit informal, comparison of .357 Magnum and .38 Special ammunition performance by testing their penetration capabilities in a frozen lake. The host, Mr. Madness, uses a Smith & Wesson Model 66 to fire both Federal American Eagle loads, highlighting the significant difference in impact and penetration depth, with the .357 Magnum proving far more potent. The test also touches on projectile recovery, with the JSP bullet from the .357 Magnum being successfully retrieved.

This video from TheYankeeMarshal compares .357 Magnum and .38 Special +P for self-defense, with an expert instructor's perspective. It delves into specific ammunition performance metrics like muzzle velocity and energy, highlighting that while .357 Magnum generally offers more power, certain high-performance .38 Special +P loads can rival its energy output. The analysis emphasizes that practical self-defense choices depend heavily on shooter proficiency, recoil tolerance, and the specific ammunition selected, with an extra round in a .38 Special +P revolver potentially outweighing a marginal power difference for some users.

This video, presented by an expert with deep knowledge of firearms ballistics and safety standards, explores the significant power of the .357 Magnum cartridge. It details its historical development, superior velocity and penetration capabilities compared to .38 Special, and crucial considerations like extreme muzzle blast, flash, and the risk of over-penetration. The guide emphasizes responsible ammunition selection, practice, and understanding the trade-offs of this potent handgun round.

The video discusses the critical debate between bullet penetration and expansion in self-defense ammunition. The speaker, Yankee, leans towards penetration, believing it's more crucial for reaching vital organs, especially when encountering barriers like windshields or car doors. While expansion creates a larger wound channel, insufficient penetration can render it ineffective. The discussion highlights that achieving maximum of both is often not feasible, and a balance is sought, with different calibers and bullet designs offering varying trade-offs.

This guide outlines seven essential firearms for a zombie apocalypse scenario, emphasizing practicality, logistics, and reliability over aesthetics. The selections include a 16-inch AR-15 carbine in 5.56 NATO, a Glock 19 Gen 5 in 9mm, a 12-gauge pump shotgun, a .357 Magnum lever-action rifle, a .357 Magnum revolver, a 9mm PCC, and a suppressed .308 bolt-action rifle. Each choice is justified by its specific advantages in maneuverability, ammunition availability, shootability, and effectiveness in various survival situations.

This video explores the compatibility of a 50 BMG cartridge with a 12 gauge flare gun. The experiment reveals that while the cartridge fits, the flare gun's mechanism cannot ignite the tough 50 BMG primers. However, it successfully fires a standard 12 gauge blank, highlighting the difference in primer hardness. The content is presented from a hobbyist perspective, focusing on experimental curiosity rather than professional instruction.

This video from Tática Civil, featuring an expert instructor, explains the dangers of firing upwards due to projectile drop and terminal velocity. It demonstrates the safe use of 9mm shot shells for controlled demonstrations, highlighting the Canik Mete MC9 Prime with a Gideon Valor red dot sight. The instructor emphasizes crucial firearm safety protocols.

This guide details an experimental test to debunk the myth that a .50 BMG round passing near a target can be lethal. Using a ballistic mannequin, cardboard indicators, and a concrete backstop, the test demonstrates that a near miss from a .50 BMG round does not impart enough shockwave or air pressure to cause fatal injury, though the projectile itself possesses immense kinetic energy as evidenced by its impact on the concrete block. The test was conducted objectively by an individual with high authority, indicated by their empirical testing methods and proper safety protocols.

This video explores the surprising functionality of a realistic toy shotgun, the M870 by Dart Armory. The presenter tests if it can chamber and cycle real 12-gauge shotgun shells, comparing its operation to a Mossberg 590. The toy shotgun successfully loads, chambers, and ejects real shells, demonstrating a high degree of realism in its mechanical operation.
