How Deadly Are Colibri Bullets?

This review covers the Ruger SR22P, a .22 LR pistol initially purchased as a first firearm due to its beginner-friendly design and manageable recoil. The speaker details its features, including a 10-round magazine capacity and hammer-fired action. Despite the SR22 series being discontinued, the speaker acquired a 'long slide' variant, comparing its trigger pull and physical characteristics to the original model. The review highlights the pistol's reliability over extensive use.

SPN Firearms provides a critical review of the Taurus Tuc22 .22 LR pistol, initially deeming it unreliable and inaccurate. While performance improved at closer ranges during a shooting test, the instructor, with extensive experience across various firearms, suggests better .22LR options exist for self-defense and recommends alternative calibers for improved reliability.

This video tests a viewer-suggested DIY suppressor method using a golf ball launcher on a Bersa Thunder .22 pistol. Experiments with standard and subsonic .22 LR ammunition, both with and without tissue packing, failed to achieve any significant sound suppression. The host demonstrates proper range safety and discusses the principles of sound suppression.

This comprehensive review details the performance of CCI Uppercut .22 LR ammunition, specifically its velocity, accuracy, and terminal ballistics. Testing conducted with a Ruger 22 Charger and a Caldwell chronograph revealed significantly higher velocities than advertised. Ballistics gel tests demonstrated effective expansion and penetration, with the speaker noting potential improvements with stabilizing braces for accuracy.

This review provides an in-depth look at the Ruger LCP II LiteRack in .22 LR, tested under extreme cold conditions (-13°F). The instructor highlights its exceptionally light recoil, ease of racking (LiteRack feature), and reliable performance with various ammunition types. It's presented as a viable option for everyday carry, especially for those prioritizing manageable recoil and ease of use over raw power, with comparisons to .38 Special and .45 ACP firearms.

The .17 HMR is an exceptionally effective varmint round, delivering high velocities and violent projectile fragmentation upon impact. While it causes significant tissue damage and temporary cavity effects, its shallow penetration limits its effectiveness against larger targets or in self-defense scenarios due to projectile disintegration. The .22 LR, surprisingly, offers deeper penetration with less dramatic expansion.

This comparison tests the .50 AE Desert Eagle against the .44 Magnum in various barrier tests, including wood, steel, sand, and concrete. While both calibers showed impressive power, the .50 AE demonstrated superior performance in ballistic gel with deeper penetration and a larger wound channel. Ultimately, the video questions if the .50 AE's marginal gains justify its significantly higher cost per round compared to the versatile .44 Magnum.

This video provides a detailed comparison between .223 Remington and 5.56 NATO ammunition, demonstrating their performance differences through rigorous barrier testing. While visually identical, 5.56 NATO shows a slight advantage in velocity and energy. Crucially, 5.56 NATO exhibits superior barrier penetration against lumber and steel, whereas .223 Remington struggles. Specialized rounds like M855A1 also show enhanced performance against sand barriers.

This video tests the lethality of various 'less lethal' shotgun rounds, including rubber buckshot, bean bags, and specialized projectiles. The .410 rubber buckshot demonstrated significantly higher velocity and penetration than 12-gauge versions. Bean bag rounds proved to be the most damaging, causing substantial plywood destruction and ballistic gel displacement, leading the host to conclude they are the most lethal 'less lethal' option.

This video compares 9mm, .40 S&W, and .45 ACP through various barrier tests including lumber, sand, and concrete, alongside ballistics gel testing. While all calibers performed similarly through most barriers, the .40 S&W showed slightly better penetration and expansion in ballistics gel. The host ultimately favors 9mm due to its lower recoil and higher capacity, despite the .40 S&W's respectable performance.
