Description
Hodgdon Retumbo is a slow-burning rifle powder with a burn rate optimized for magnum calibers. This extruded propellant is specifically designed for large-capacity cases to maximize velocity and energy potential. Its large-grain structure provides a dense load, which can be beneficial in high-volume cases, while also promoting consistent ignition and burn characteristics. Retumbo is renowned for its excellent metering properties in volumetric systems, ensuring reliable performance despite its extruded form. Handloaders often choose Retumbo for its exceptional temperature stability, offering consistent performance across a wide range of environmental conditions. It is particularly suitable for long-range applications in calibers such as 7mm Remington Magnum, .300 Winchester Magnum, and .338 Lapua Magnum, where optimal ballistic performance is critical. During load development, users should conduct thorough testing due to its slower burn rate and potential for slightly compressed loads to ensure peak performance. Retumbo's ability to maintain pressure and velocity, combined with the manufacturer’s strong reputation for quality, makes it a staple for those seeking superior results in rifle reloading.
