This video details the process of creating a custom seating stem for 75gr Hornady BTHP bullets to address concentricity issues with compressed loads. Testing reveals that shorter seating depths (around 2.254" OAL) improve bullet alignment and accuracy, with the best group measuring 0.59" at 100 yards. The host emphasizes the importance of matching seating stems to specific bullet profiles for optimal handloading results.

This video details the reloading process for .223 Remington using 62gr Hornady BTHP bullets with H4895 and AR-Comp powders. It highlights the accuracy potential of the Hornady bullet, with AR-Comp achieving a 0.468-inch group at the starting load. The testing was conducted on a PSA AR-15 with an 18-inch barrel, showing varying velocities and pressure signs with different powders.

This video fine-tunes Mk 262 clone loads using Accurate 2520 and CFE 223 powders to match Black Hills 77gr OTM factory ammunition. Accurate 2520 at 25.2 grains with a Sierra 77gr SMK bullet achieved 2768 fps and a 0.416" group, while a Nosler 77gr CC at 25.0 grains yielded 2730 fps and a 0.371" group. CFE 223 showed lot-to-lot variation and degraded accuracy at higher pressures.
