Description
Hodgdon RETUMBO® is an extruded magnum powder designed expressly for really large overbored cartridges. Its intended applications include the 7mm Remington Ultra Magnum, 300 Remington Ultra Magnum, and 30-378 Weatherby Magnum, along with similar large-capacity magnum cartridges supported by published Hodgdon data.
For these cartridges, RETUMBO® adds 40–100 fps more velocity when compared with other normal magnum powders. That performance focus makes it a purpose-built option for handloaders working with the big overbored magnum class rather than a general-purpose powder choice.
RETUMBO® is part of Hodgdon’s Extreme Powder line and is described as ideal for big game hunting under all types of conditions. As always at the loading bench, select only current published data for the exact cartridge and components in use.
Made in Australia, Hodgdon RETUMBO® is available in 1 lb. and 8 lb. containers. Choose the container size that fits your reloading needs and keep the label close at hand—the data matters.

Hodgdon Retumbo
Compared to H1000 and N570, .300 Norma Mag. Borden Bigfoot action, Brux barrel(Heavy Varmint). Retumbo has been the most consistent and accurate powder for my rifle setup. Love this stuff!

Retumbo Rifle Powder
I loaded the 300 Remington Ultra Mag case with the Berger 215 grain Hybrid target bullet and Hodgdon Retumbo Powder and worked up a load that produced an ES of 6.6 fps and a SD of 2.7 fps which produced good accuracy and velocity. This is a fantastic powder that performs very well with magnum loads. Very happy with it. Thank you Hodgdon for making this available through your web site.

I use this powder for my 338 Lapua
I used one grain under Max for the type of bullet I was using and was very pleased with the results at 200 yards.

Retumbo
I purchased Retumbo because it is a single base powder. Because of past usage of single base powders under varying weather conditions. Not being able to purchase primers I want for a specific powder, like double base and sphere powder specifically I like using a hotter primer and most people should. Another consideration is barrel length. The Retumbo will be used in a 7mm rm 24" inch barrel with a 162 gr projectile.
