5.45x39 vs 7.62x39: ANY Difference On Mild Steel?

This YouTube video appears to be a direct comparison between two popular handgun calibers, .22LR and 9mm, with a specific focus on their performance when suppressed. The title "22lr Vs 9mm Suppressed!" clearly indicates a head-to-head evaluation. While no specific firearm models are mentioned, the video will likely showcase different handguns chambered in these calibers and demonstrate the sound reduction effectiveness of suppressors on each. It's geared towards firearm enthusiasts interested in caliber performance, suppressed shooting, and practical comparisons for potential firearm purchases or understanding ballistic differences.

This YouTube video compares the lethality of subsonic versus supersonic .22LR ammunition. The title directly poses the question of which type is more lethal, indicating a comparative analysis of their terminal ballistics and effectiveness. The content likely explores the physics behind these rounds, potentially including penetration, expansion, and energy transfer, to determine their suitability for various applications where lethality is a primary concern.

This video explores the utility and value of using .22LR subsonic ammunition. It delves into the characteristics of this type of ammunition and discusses its potential applications, likely in comparison to standard .22LR loads. The analysis aims to help viewers decide if subsonic .22LR is a worthwhile option for their specific firearm needs.

This YouTube video presents a challenge comparing the power of two popular revolver calibers: the .357 Magnum and the .38 Special. The title explicitly states the comparison, indicating a likely analysis of ballistic performance and practical differences between the two ammunition types.

This YouTube video, titled ".45 ACP: o poder de parada dessa munição é tudo isso mesmo?" (Is the stopping power of this .45 ACP ammunition really all that?), delves into the effectiveness of the .45 ACP cartridge. Based solely on the title, the content likely explores the terminal ballistics and practical stopping power of this well-known handgun caliber, possibly comparing it to others or discussing its historical significance and performance in real-world scenarios. It aims to answer whether the reputation of .45 ACP's stopping power is fully justified.

This video directly compares the popular 9mm cartridge to the .40 S&W, challenging common perceptions about their effectiveness. The title poses a provocative question, suggesting a deeper dive into ballistics, recoil, capacity, and practical applications for both calibers. It aims to educate viewers on the nuances of these widely used handgun rounds, likely appealing to new and experienced firearm owners interested in cartridge selection for self-defense, range use, or general knowledge.

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.
