Hodgdon RET1 Extreme Retumbo Magnum Rifle 1 lb - 50608

Hodgdon Powder Co. introduces Retumbo, a true magnum rifle powder. Retumbo was designed for such cartridges as the 300 Remington Ultra Magnum, 30-378 Weatherby, 7mm Remington Ultra Magnum, the 7mm STW and many others with very large capacity cases and relatively small bores. Shooters can expect up to 40-100 feet per second more velocity than other magnum powders, depending on choices of bullets and primers. The Retumbo is an extruded propellant that incorporates all the great features of Hodgdon’s Extreme family of powders. Hodgdon Extreme powders are insensitive to changes in hot and cold temperatures.
