This video compares the performance of four Hodgdon powders (H335, CFE223, Varget, BL-C2) in a 16-inch barreled Tavor 7 chambered in .308 Winchester. The testing focuses on velocity loss compared to advertised 24-inch barrel data, using maximum charges with 150-grain FMJBT bullets. CFE223 yielded the highest velocity, while BL-C2 showed the least velocity loss, indicating good performance in short barrels.

This video explores maximizing velocity for the 6.5 Grendel cartridge in 16-inch and 18-inch barrels using 123-grain ELD Match bullets. The instructor tests four popular powders: CFE 223, Varget, H335, and BL-C(2), comparing measured velocities against advertised data. The analysis highlights how barrel length impacts velocity and identifies powders that perform best in shorter carbine setups, noting that no over-pressure signs were observed at maximum loads.

This video details the initial function testing of 70 handloaded 6.5 Grendel rounds using seven different powders. The presenter focuses on forming new brass, addressing minor extractor marks, and conducting round-robin testing at 200 yards to gather baseline velocity and accuracy data. The results indicate AR Comp shows promise for accuracy and consistent velocity, with no significant performance degradation observed due to fouling after 70 rounds, paving the way for more rigorous load development.
