Hodgdon Retumbo Extreme Smokeless Powder – 1lb & 8lb Bulk

Hodgdon Retumbo is a magnum extruded powder designed expressly for the world’s largest overbored cartridges. As a premier member of the Hodgdon Extreme series, Retumbo is engineered to provide an additional 40–100 fps more velocity in massive-capacity cases compared to other standard magnum powders.

Whether you are hunting elk in the high Rockies or competing in long-range matches, Retumbo provides the thermal stability and raw power required for consistent, match-grade performance in any environment. Its reputation for delivering low standard deviations (SD) and high velocities has made it the go-to propellant for the most demanding long-range shooters.

Why Choose Hodgdon Retumbo Powder?

• Significant Velocity Gains: Specifically formulated to push the limits of overbored cartridges, giving you a distinct advantage in flat trajectory and downrange energy.

   

• Extreme Temperature Stability: Part of the Hodgdon Extreme line, ensuring your point of impact remains consistent from freezing winter hunts to hot summer range sessions.

   

• Optimized for Overbore Magnums: The industry leader for cartridges like the 7mm RUM, .300 RUM, and .30-378 Weatherby.

   

• Superior Consistency: Extruded grains are cut for precise metering and uniform ignition, resulting in the tightest possible groups at extreme distances.

• Clean Burning: Formulated to minimize barrel fouling, allowing for more shots between cleanings without sacrificing accuracy.
