This video details a reloading process for the .223 Remington cartridge, focusing on testing two lead-free bullets: the 70gr Hornady GMX and the 70gr Barnes TSX, using Power Pro 2000 MR powder. The instructor systematically tests various bullet seating depths to optimize accuracy, observing trends in group size, velocity, and consistency. The goal is to develop a reliable load for whitetail deer hunting.
This video provides a detailed analysis of the 120gr Speer Gold Dot bullet for the 6.5 Grendel cartridge. The instructor, Johnny, conducts extensive load development using Power Pro 2000-MR and AR-Comp powders, presenting chronograph data, group sizes, and ballistic gel performance. He concludes that while velocities with Power Pro 2000-MR were lower than expected, the AR-Comp loads offered surprisingly good velocity and accuracy, making the 120gr Gold Dot a promising option for deer hunting.
