Hodgdon H4895 powder (AR2206H)

H4895 is a highly versatile, medium-burn-rate extruded rifle gunpowder manufactured by Hodgdon Powder Company.
Originally derived from military surplus powder used for the .30-06 Springfield cartridge, it was the very first propellant sold by the company’s founder, Bruce Hodgdon.
Today, it is widely celebrated among ammunition reloaders for its match-grade accuracy, extreme temperature stability, and structural safety when developing reduced-velocity ammunition.Key Characteristics & Uses
Extremely Versatile: It performs exceptionally well across a broad spectrum of small-to-medium calibers, including the .223 Remington, .308 Winchester, .30-06 Springfield, and .243 Winchester.The "60% Rule" for Reduced Loads: Hodgdon officially supports H4895 for creating low-recoil rounds. It is the slowest-burning propellant that still ignites uniformly at significantly reduced capacities. Reloaders can safely multiply the maximum listed charge weight by 60% (0.60) to build youth, training, or light plinking loads.
Temperature Insensitivity: As a member of Hodgdon’s "Extreme" line of propellants, it maintains stable velocities and pressures whether shooting in freezing winters or scorching summer heat.
Physical Structure: It features short-cut granules (kernels) that meter smoothly through automatic powder drops and scale measures
