308 vs 7.62x51: Not Close At All?

This YouTube video offers a direct comparison between subsonic and supersonic ammunition for the .22LR caliber. The content likely delves into the performance differences, potential applications, and characteristics of each type of .22LR round. Viewers can expect insights into how the speed of the bullet affects factors like noise levels, recoil, and terminal ballistics, making it a valuable resource for .22LR enthusiasts considering ammunition choices.

This review by Roger Barrera (QVO Tactical) tests the accuracy of the FN SCAR 17S, a rifle FN has discontinued. Despite its lightweight barrel, the SCAR 17S demonstrated capability, especially with heavier match-grade ammunition. The review highlights the significant impact of ammunition choice and trigger quality on the rifle's precision, offering practical insights for potential owners.

This test compares subsonic and supersonic .22LR ammunition lethality using Clear Ballistics gelatin and a cloth barrier. Results indicate that heavy subsonic FMJ rounds can penetrate beyond the FBI's 12-inch minimum, challenging the assumption that they are less deadly than supersonic hollow points. The supersonic hollow point demonstrated expected mushrooming.

This video provides a direct, visual comparison between the .45 AUTO and 10mm AUTO calibers, featuring a 1911-style pistol and a CZ-style pistol. The demonstration includes loading procedures and live-fire performance on an outdoor range, highlighting differences in recoil and sound. The content is presented by an experienced individual, offering practical insights into these popular handgun cartridges.

This video showcases the HK MR308, the civilian variant of the HK 417, highlighting its premium status and performance. The speaker demonstrates a live fire session, noting the rifle's smooth operation. The review also includes a promotional mention for Kore Essentials EDC belts with a discount code. The current market price for the MR308 is discussed, with the speaker deeming it 'absolutely insane'.

This video provides an expert-level comparison of 5.56x45mm NATO and 7.62x51mm NATO calibers, drawing on combat experience and ballistic data. It highlights 5.56's advantages in logistics, recoil management, and close-quarters combat, while 7.62 excels in barrier penetration and long-range effectiveness. The 'best' caliber is mission-dependent.

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.
