Description
IMR 7828 SSC is a popular slow-burning powder designed for rifle loads, making it an ideal choice for magnum calibers requiring high-energy propellants. Its burn rate is particularly suited for high-velocity applications where efficiency and consistency are paramount. As a "short cut" (SSC) form of 7828, this powder offers enhanced metering properties through most powder measures, ensuring uniform charges and reducing variation in pressure and velocity. This characteristic is particularly beneficial during load development as it aids in achieving precise, repeatable results. 7828 SSC is praised for its excellent temperature stability, providing consistent performance across a wide range of weather conditions. This trait makes it a reliable choice for hunters and long-range shooters who demand precision in varying climates. Commonly paired with calibers such as .300 Winchester Magnum, 7mm Remington Magnum, and .338 Lapua Magnum, this powder enables excellent case fill and optimal ballistic performance. Handloaders appreciate its capacity to meet diverse needs, providing flexibility and precision at the bench.
