About this powder
H322 is a proven benchrest extruded powder that has been filling .222 Rem and .223 Rem cases since the 1960s. Part of Hodgdon's Extreme series, its temperature-stable formulation makes it reliable from winter varmint sessions to summer benchrest matches. Small-grained for better metering than standard extruded powders.
