Videos tagged with Permanent Cavity

This video provides an expert-level guide to understanding and analyzing ballistic gel tests. It details the limitations of gel compared to living tissue, the environmental sensitivities of gel testing (especially temperature), and the differences between organic and synthetic gel blocks. The instructor emphasizes proper calibration techniques and outlines key metrics for assessing projectile performance, including penetration depth, cavity diameter, neck length, trajectory, and fragment analysis through dissection.

This video critically examines the 8.6 Blackout cartridge, questioning its purported advantages, particularly the emphasis on a 1:3 twist rate. The presenter argues that while the cartridge offers more energy than 300 Blackout, its significant bullet drop and limited effective range make it less ideal for hunting compared to other alternatives. The analysis delves into the physics of rotational energy, suggesting its contribution to terminal ballistics is often overstated and that faster twist rates can lead to increased barrel and component wear.

This video from Lucky Gunner Ammo delves into the critical aspects of terminal ballistics, explaining how projectiles behave upon impact. It highlights the significant performance differences between rifle and pistol rounds, emphasizing factors like permanent and temporary cavity formation, bullet deformation, and fragmentation. The content is presented with a focus on practical application for defensive shooting scenarios.

This video provides a ballistic gel test of Winchester USA Ready 124gr 9mm +P ammunition, fired from a Taurus G2 with a 3-inch barrel. The test evaluates penetration, expansion, and weight retention through single-layer t-shirt and four-layer denim barriers. The instructor notes the ammunition's performance, including significant permanent cavity creation and expansion, while also cautioning against using +P rounds in non-rated firearms like the Taurus G2.

This video presents a ballistics gel test of Federal Fusion 150-grain 300 Blackout ammunition fired from a 9-inch barrel AR-15. The test provides insights into penetration depth, permanent wound cavity, and bullet expansion, with the speaker considering this round for home defense. The results indicate significant penetration and expansion, with the bullet reaching 25 inches and creating a wound channel of approximately 13.5 inches.

This video details a ballistics gel test of Underwood Ammo's 357 SIG 125gr Gold Dot JHP load. The test was conducted using a Glock 22 with a Glock 31 barrel. Key performance metrics including velocity, penetration, expansion, and retained weight were measured and analyzed, with comparisons made to a previous test of a similar Speer load.

This video details a ballistics gel test of the Winchester Ranger T 45 ACP 230gr JHP ammunition, product number RA45T. The test, conducted using a Springfield Armory TRP with a 5-inch bull barrel, demonstrated excellent performance with significant expansion and good penetration. The presenter highlights the bullet's lineage from the Black Talon and SXT designs, noting its effectiveness in creating a substantial permanent wound channel.

This video delves into terminal ballistics, demonstrating the performance of 8mm PAK ammunition against ordnance gel and water. It analyzes permanent and temporary cavities, as well as penetration depth, highlighting the effectiveness of improvised firearms. The demonstration shows the 8mm PAK bullet exceeding FBI penetration standards, comparing favorably to commercial pistol cartridges and emphasizing its potential lethality even at short distances.

This video provides a demonstration of the Martini-Henry Mk.II rifle, focusing on its terminal ballistics. It details the effect of the rifle's projectile on a ballistic gel block, explaining concepts like permanent cavity, temporary cavity, and penetration depth. The description compares the Martini-Henry's performance to modern handgun cartridges, noting its reliance on a large permanent cavity for incapacitation due to its lower velocity and harder bullet composition. The video also touches on the historical significance of the Martini-Henry, its role in the film 'Zulu', and its technical specifications as a single-shot, lever-actuated rifle.

This video delves into the principles of terminal ballistics using a firearm demonstration. It explains the creation and use of ordnance gelatine and Permagel for testing, focusing on the concepts of permanent cavity, temporary cavity, and penetration depth. The analysis highlights the performance characteristics of the 9x19mm cartridge, comparing it implicitly to larger calibers like .45 ACP, and discusses survivability of pistol bullet wounds. The demonstration also visually illustrates bullet deceleration and the temporary cavity effect within the gel block.

This video demonstrates the terminal ballistics of the SA80 L86A1 Light Support Weapon firing a 5.56x45mm NATO round into a 10% ballistic gelatine block. It explains the principles of permanent cavity, temporary cavity, and penetration, using the gelatine block as a scientific standard to simulate human tissue. The description also touches on the history and design intent of the 5.56mm round as an intermediate rifle cartridge.

This video demonstrates the terminal ballistics of the SA80 L86A1 Light Support Weapon firing 5.56x45mm NATO ammunition into a 10% ballistic gelatine block. The content explains the scientific principles behind ballistic gel testing, including the formation of permanent and temporary cavities, and the importance of penetration depth. It details how gelatine simulates human tissue for wound track analysis and discusses the characteristics of the 5.56mm round, its origins with the AR-15/M16 platform, and its effectiveness when yawing. The description also provides a link to the Royal Armouries collection.
