Será que o recuo de uma arma te empurra no gelo?

This expert guide, informed by a retired Green Beret with TBI, details the overlooked risk of concussions and brain damage from blast waves at indoor shooting ranges. It explains how reflected shockwaves from walls and ceilings can lead to cumulative impacts, exceeding military safe exposure limits, particularly with rifle fire. The guide emphasizes awareness and suggests limiting high-volume rifle use in such environments.

This expert-level guide, presented by an experienced firearms instructor, details the critical differences between .22LR and .22HMR (or .22 Magnum) cartridges. It highlights the potential dangers and malfunctions that can occur when using the wrong caliber, specifically demonstrating how .22LR can cause casing issues in a .22 Magnum firearm. The guide emphasizes the importance of proper ammunition identification for safe and effective shooting.

This video from Tática Civil demonstrates the inherent dangers of firing old, corroded ammunition. The presenter tests 9mm, .38 Special, and .223 cartridges, highlighting inconsistent performance and potential firearm failures. A key takeaway is the importance of safety protocols, such as checking for squib loads after a misfire and understanding the risks associated with different firearm actions.

This guide demonstrates how to prepare a double barrel shotgun for a hypothetical zombie apocalypse. It covers opening the breech, modifying 12 gauge bird shot shells into 'zombie slugs' using a utility knife, loading, firing, and tactical reloading. The instruction emphasizes the immediate availability of a second shot with a double barrel and the importance of ammunition conservation.

This guide, presented by a firearms instructor, emphasizes the importance of realistic dry fire practice. It strongly advises against racking the slide after each trigger pull, as this develops poor muscle memory. Instead, it recommends using tools like the DryfireMag to achieve a resettable trigger, enabling realistic follow-up shot practice and improving overall training effectiveness.

This instructional video from American Outlaw emphasizes a proactive philosophy for home defense firearm readiness. Lead instructor demonstrates critical techniques for quickly chambering a round, dynamic safety manipulation integrated with aiming, and the paramount importance of trigger discipline. The content is geared towards individuals who may not keep a round chambered but need to be proficient in immediate readiness during a home invasion scenario.

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.
