Videos tagged with OAL Adjustment

This video details the process of developing a hunting load for the 308 Winchester using 165-grain Hornady GMX bullets and AR-Comp powder. The instructor systematically adjusts the overall length (OAL) of the cartridges, starting from 2.740 inches and decreasing in 0.010-inch increments, while maintaining a consistent powder charge. Ballistics data, including velocity and group sizes, are recorded and analyzed at each step to identify the most accurate and reliable load for hunting in thick woods. The process also includes insights into brass preparation and sizing die selection.
