This video provides a detailed review of Frontier's FR262 77gr OTM ammunition, a budget clone of the MK262 load. The reviewer tested it across five different AR-15 barrels, noting significant velocity variation between lots and individual shots, leading to poor extreme spreads and standard deviations in most cases. While some groups were decent, many exhibited flyers and inconsistent performance, particularly in shorter barrels. The FR262 generally achieved high velocities but struggled with accuracy compared to premium loads.
This video features a discussion between a firearms instructor and Pete from Defiant Munitions, exploring the high cost of ammunition, the performance benefits of solid copper projectiles, and the complexities of subsonic ammunition manufacturing. They delve into factors affecting ammunition performance, such as temperature sensitivity and environmental conditions, and touch upon the future of ammunition technology like 3D printed casings. The conversation highlights the importance of rigorous testing and understanding ammunition behavior in various scenarios.
This video focuses on the critical role of consistent powder charges in ammunition for achieving optimal long-range shooting performance. It highlights how minimizing velocity variations is key to accuracy at extended distances. The description also encourages viewers to share their own methods for maintaining velocity consistency and promotes subscribing to the Gunwerks YouTube channel for more content on long shots, tough shots, shooting tips, DIY projects, and ballistics.
This video investigates significant velocity variations in 300 Blackout subsonic loads, specifically 147gr with Accurate 1680 powder. The presenter replicates a commenter's findings where powder position within the case dramatically affects muzzle velocity, with swings up to 200 ft/s observed. This phenomenon is linked to inconsistent ignition, particularly in low-charge-weight, high-capacity cartridges. The testing involved comparing CCI BR4, SNB, and Federal AR Small Rifle Match primers, shooting rounds with powder settled horizontally versus vertically (powder towards the primer).
