This video from Civilian Tactical provides a detailed look at the terminal ballistics of the 7N6 5.45x39mm round, often nicknamed the 'poison bullet'. Through controlled testing with ballistic gelatin, the host demonstrates how the unique design of the 7N6 round causes it to tumble rapidly upon impact, leading to a significant energy dump and a much larger wound cavity compared to standard 5.45x39mm ammunition. The expert-level demonstration highlights the effectiveness of this military surplus round.

This video debunks common myths surrounding 55-grain FMJ 5.56x45mm NATO ammunition for WROL/SHTF scenarios. The speaker, Trench Grenade, emphasizes that while 55-grain FMJ may experience increased deviation past 350 meters and is less effective in shorter barrels (under 14.5 inches) due to reduced velocity and yaw capability, it remains a viable option for home defense and general use with longer barrels (14.5 inches and above). The discussion highlights the importance of barrel length in achieving optimal projectile performance and yaw for terminal ballistics.

This video, featuring Jesse (Boondock Ballistician) and Gary Roberts (DocGKR), delves into the critical aspects of 5.56x45mm NATO terminal ballistics. It explains how bullet design, velocity, fragmentation, and yaw significantly influence terminal effects, often surpassing the impact of caliber choice alone. The discussion covers various ammunition types, from M193 and M855 to specialized rounds like Speer Gold Dot and Federal Fusion, emphasizing that while advanced ammunition offers benefits, superior shot placement and shooter skill are paramount for effective performance.

This video from Classic Firearms explains the critical relationship between rifle twist rates and ammunition bullet weight for optimal ballistic stabilization and accuracy. The hosts, Matt and Jason, detail how different twist rates (e.g., 1:7, 1:8, 1:9) are designed to stabilize specific bullet weights and lengths. They emphasize that using the wrong ammunition can lead to under or over-stabilization, resulting in poor accuracy, keyholing, or yawing. The discussion covers common calibers like 5.56 NATO and 300 Blackout, providing guidance on selecting appropriate bullet weights for various twist rates to maximize rifle performance.

This video tests Wolf's 6.5mm Grendel 100gr FMJ ammunition using a 12.5" upper in a controlled ballistic gelatin setup. The analysis focuses on penetration, yaw, expansion, fragmentation, and retained weight, captured with a high-speed camera. Key metrics are provided, including penetration depth of 20.6", 92.8gr retained weight, and an average velocity of 2,337.00 fps. The test assesses claims about early yaw and temporary stretch cavity formation for this specific ammunition.

This guide details the procedure for conducting a ballistic gel test on M855 ammunition from a Short Barreled Rifle (SBR), as demonstrated by an expert from ARFCOM. It covers setup, firing, observation of impact dynamics including cavitation and fragmentation, and measurement of wound channels. The expert analysis highlights M855's dependence on yaw for fragmentation and its effectiveness at close range.
