The IMR 4831 smokeless rifle powder delivers consistent performance for medium to large rifle cartridges, making it a staple choice for precision shooters and hunters. This single-base extruded powder provides excellent metering characteristics and temperature stability across diverse shooting conditions. Manufactured to strict quality standards, IMR 4831 maintains lot-to-lot consistency that competitive shooters and reloaders depend on for predictable results.
What Makes This Different
IMR 4831 features a medium burn rate that bridges the gap between faster pistol powders and slower magnum rifle powders. The extruded granule structure ensures uniform ignition and consistent pressure curves compared to ball powders. Temperature sensitivity remains minimal across seasonal variations, with velocity changes typically under 1 fps per degree Fahrenheit. This stability translates to more predictable point of impact shifts during temperature swings.Key Features
