Fiocchi 55gr M193 Ammo Lot Test - From Great to Garbage?

This video compares the terminal ballistics of 5.56x45mm NATO (M855 Green Tip) and 7.62x39mm (Tula) ammunition using gel block testing. The 5.56mm round demonstrated significant expansion and fragmentation, causing substantial damage to the test setup. The 7.62x39mm round, while also expanding, showed greater penetration, passing through the gel block and the table. The test highlights the different performance characteristics of these popular calibers in terms of tissue damage and penetration.

This video explores the pros and cons of 20-inch barrels on 5.56 gas guns, primarily for competition. The instructor emphasizes that barrel length primarily affects velocity and maneuverability. While 18-inch barrels offer better maneuverability in tight spaces, 20-inch barrels provide increased velocity, leading to flatter trajectories and retained energy at longer distances, which is beneficial for competition.

This video details a friendly rifle competition between a PSA Dissipator build and a Zastava M70, focusing on 50-yard group shooting.

This video provides an expert-level analysis of the ArmaLite AR-180's practical accuracy, extending to 500 yards. The review highlights the rifle's surprising performance despite its utilitarian construction and simple iron sights. It delves into the historical context of Eugene Stoner's design, its association with the IRA, and its influence on modern firearms. The assessment is delivered with high authority, characteristic of the 9-Hole Reviews channel's data-driven approach.

This video provides a demonstration of the FN SCAR 17S and 16S rifles, chambered in 7.62x51mm NATO and 5.56x45mm NATO respectively, alongside the FN 309 MRD handgun in 9mm. The footage showcases safe firearm handling and controlled rapid fire from a high-authority instructor, highlighting the operational differences between the SCAR variants.

This video details a competitive 'Run and Gun' event at the Sawmill Training Complex, featuring a 3.7-mile course with six shooting stages. The speaker, an experienced tactical shooter, provides an in-depth look at his Griffin Mk2 14.5 rifle and Smith & Wesson M&P 2.0 5-inch pistol setups, highlighting specific components and their performance under stress. The guide emphasizes adapting to immediate stage instructions and managing physical fatigue for optimal results.

Preston Moore, demonstrating high expertise, provides an analytical assessment of a Criterion CORE series barrel after 15,000 rounds. He details significant internal wear, including throat erosion and fire cracking, using specialized tools like borescopes and erosion gauges. Despite the degradation, the barrel still produced surprisingly acceptable groups with specific ammunition, highlighting its durability and the importance of testing worn components.

This video provides an in-depth review and accuracy test of a Ballistic Advantage AR-15 barrel. The presenter, Preston Moore, details the barrel's specifications, including its Hensley profile, 16-inch length, mid-length gas system, and 1:7 twist rate. He conducts extensive live-fire testing with four different ammunition types at 100 yards, meticulously recording group sizes, velocities, and rifle stability scores using advanced equipment. The results are compared against Ballistic Advantage's sub-MOA guarantee, offering practical insights into the barrel's real-world performance.

This video provides an in-depth accuracy test of the Sons of Liberty Gunworks 16-inch SPR barrel, featuring unique polygonal rifling and a 5/8x24 thread pitch. The instructor conducts 30-shot groups with various ammunition types, meticulously recording data on velocity, rifle stability, and group size using advanced metrics like the A-ZED score. The results demonstrate exceptional accuracy, positioning the barrel favorably against competitors.

This video provides a detailed comparison of two BCM ELW (Extreme Lightweight) barrels, examining their manufacturing consistency and on-range performance. The presenter conducts thorough bench inspections, including gauging, weighing, and borescope analysis, highlighting potential manufacturing variations. Live-fire testing involves 30-shot groups at 100 yards with various ammunition types to assess accuracy, velocity, and consistency, offering insights into the practical performance of these lightweight barrels.
