IMR 3031 Smokeless Gun Powder

IMR 3031 is a single base, extruded powder. It exhibits a medium burn speed with many uses, and has long been a favorite of 308 Match shooters using 168-grain match bullets. It is equally effective in small-capacity varmint cartridges from 223 Remington to 22-250 Remington, and it’s a great 30-30 Winchester powder.

A Go-To Medium-Burn for Rifle Shooters

IMR 3031 is a medium burn-rate rifle powder prized for its versatility across many cartridges from small-capacity varmint rounds up through classic .30-caliber hunting loads. Handloaders and match shooters have used it for decades because it combines dependable ignition with predictable velocities.

Match-Grade Results in .308 and More

Many shooters favor IMR 3031 for .308 match work with 168–178-grain bullets, where it has a track record of delivering tight groups and consistent SDs. At the same time it can be worked into lighter varmint cartridges (like .223 Rem and .22-250) and is also a traditional choice for the .30-30 Winchester. Practical load data exists for larger hunting cartridges such as .30-06 as well.

Clean Metering & Easy Reloading

IMR 3031’s extruded (stick) form meters more smoothly than many slow ball powders and gives reliable, repeatable charges on both single-stage and progressive presses. Reloaders appreciate the balance of flow-characteristics and the ability to use existing IMR/Hodgdon load tables when developing safe, accurate loads.

Real-World Stability & Flexibility

This powder offers a stable, workmanlike performance across common shooting temperatures and environments, making it a solid “one-powder” choice for shooters who want fewer variables to manage when switching between hunting, match, and range loads. Hodgdon lists IMR 3031 as a perennial favorite for a broad range of rifle uses.
