Essa bala não faz barulho nenhum!

This video explains the three primary noises produced by a suppressed firearm: the muzzle blast, the firearm's action, and the bullet's sonic boom. It details how suppressors primarily address the muzzle blast. To further reduce noise, the instructor recommends using manually operated firearms to minimize action noise and employing subsonic ammunition to eliminate the sonic boom, aiming for a suppressed shot where the bullet impact is louder than the firearm itself.

This video demonstrates the effect of firing subsonic 9mm ammunition in a highly ported, loud handgun. The presenter notes that while handguns are generally loud, specific designs like the ported De Lis nine can exacerbate noise. The test aims to see if subsonic rounds, typically used with suppressors, can reduce the perceived loudness of such a firearm, with results indicating a significant reduction in noise.

This discussion from Regular Guy Training LLC delves into the practical applications and limitations of the 300 Blackout cartridge, particularly in civilian contexts. The panel of firearms instructors and enthusiasts argues that while 300 Blackout was designed for specific military roles, its civilian utility is questionable due to reliability issues, high cost, and a lack of distinct advantages over other calibers. They emphasize that a 'fighting rifle' must be reliable, accurate, and durable, qualities they find lacking in many 300 Blackout platforms when pushed to their limits. The conversation also explores the concept of a Personal Defense Weapon (PDW) and why 300 Blackout often falls short of meeting those requirements.

Ben Stoeger discusses lead exposure mitigation strategies, emphasizing indoor range ventilation and ammunition choices. He advises against excessive thumb pressure on safeties of 1911/2011 platforms and shares his reloading habits. Stoeger's insights are based on personal experience and blood lead level testing.

This guide provides expert-level preparation tips for gas gun precision rifle matches, drawing from an experienced shooter's routine. It covers essential steps like small base sizing brass, gas system tuning, positional drills, and data confirmation at extended ranges. The advice emphasizes building solid fundamentals and efficient execution for competitive success.

This video demonstrates three methods for practicing shooting at home, focusing on reduced noise levels. It highlights the use of an air rifle, .22 LR ammunition with a long barrel, and .22 LR subsonic ammunition paired with a suppressor on a threaded barrel rifle. The presenter emphasizes quiet operation for discreet practice.

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 demonstrates a dramatic comparison between the .22 LR and .50 BMG calibers using a ballistic head model. The .50 BMG, when attached to an AR-15 platform via a Raptor upper, shows vastly superior destructive power, completely obliterating the model, while the .22 LR causes only superficial damage. The host's enthusiastic and experimental approach, combined with clear technical explanations, highlights the significant energy difference between these two rounds.
