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 details an attempt to clone Mk262 ammunition using Winchester 748 and Winchester 760 powders with 77-grain Sierra MatchKing bullets. The instructor, with experience in this series, tests various powder charges, meticulously recording velocity, group sizes, and pressure signs. While Winchester 748 proved ineffective for accuracy, Winchester 760 showed significant promise, particularly at lower charge weights, warranting further investigation.

This video details the process of cloning Mk262 ammunition using IMR 8208 XBR and Alliant AR Comp powders with 77-grain Sierra bullets. The instructor meticulously works up loads, compares Remington 7.5 and CCI No. 41 primers, and discusses pressure signs, brass longevity, and potential firearm malfunctions. The content emphasizes cautious load development and understanding individual firearm behavior.
