.223 Rem - 75gr Hornady BTHP with 19 powders
This video details a comprehensive reloading experiment testing 19 different powders with the 75gr Hornady BTHP bullet in .223 Remington. The instructor aims to find a cost-effective path to replicating Mark 262 clone performance, analyzing group sizes and velocities for each powder charge. Several powders, including Hodgdon H322, Vitavouri N135, and AR Comp, showed promising accuracy, with AR Comp emerging as a potential top contender for further development.
