Smokeless Powder

Product Overview

This magnum, extruded powder was designed expressly for the really large overbored cartridges such as the 7mm Remington Ultra Magnum, 300 Remington Ultra Magnum, 30-378 Weatherby Magnum, etc. Retumbo adds 40-100 fps more velocity to these cartridges when compared to other normal magnum powders.

In addition, it is an Extreme Powder, making it perfect for big game hunting under all types of conditions.

    Retumbo is my absolute most favorite gunpowder for the big magnums. I get extra velocity and great shot repeatability.

    Awesome for Large Magnum

    Posted by Greg on Jul 3rd 2023

    Perfect for my savage 110 long range hunter chambered in 338 LM. 87.5 gr behind a 300 gr A-Tip yields a .6 MOA.

    Best slower burn rate powder I’ve used

    Posted by Kevin H on Apr 24th 2022

    This is by far the best powder in my .300 Norma improved. Might as well be fairy dust but if you can get some it’s going to work well in big .30s for sure. Very temp stable and very consistent ES. Hoping to find some more when I can!

    Undoubtedly the best Magnum powder out there. Use I 7mm rem mag and 270 WSM with excellent accuracy and speeds.
