Description
Hodgdon's H322 powder, with a burn rate of 3.1, is categorized as a medium-fast rifle propellant. Its burn rate is particularly well-suited for high-performance shooting in smaller rifle calibers, catering to precision reloaders. The powder is an extruded form but adheres to a fine granulation that allows for excellent metering, ensuring consistent charges in volumetric dispensing. A key attribute of H322 is its notable temperature stability, which provides reliable performance across varied weather conditions, maintaining consistent velocities and pressure characteristics. This powder is especially favored in popular calibers such as .223 Remington and .308 Winchester, where it delivers exceptional accuracy and clean burning characteristics. Load development with H322 should focus on gradual increments to fine-tune performance, as its medium-fast nature offers versatility across numerous bullet weights. For experienced handloaders, H322 provides distinct advantages in precision shooting, thanks to its uniform burn properties and minimal deviation in performance, solidifying its reputation in the reloading community.
