IMR 4064 Smokeless Rifle Powder delivers consistent performance across medium-capacity rifle cartridges from .308 Winchester to .30-06 Springfield. This single-base extruded powder maintains temperature stability and provides excellent metering characteristics for precision handloading applications.
What Makes This Different
IMR 4064 features a medium burn rate that bridges the gap between faster pistol powders and slower magnum rifle powders. The extruded granular structure ensures uniform ignition and consistent pressure curves across temperature ranges from -40°F to 140°F. This powder produces lower extreme spread velocities compared to ball powders, typically showing velocity variations under 20 fps in controlled testing.Key Features
