IMR 7828SSC Powder has precisely the same melt away amount and utilizes precisely the same data as normal IMR 7828. Even so, due to really small kernels, metering is almost nearly as good as with a spherical powder.IMR 7828 SSC is my go-to powder for .300 Acquire Mag. The super-limited grains make metering a breeze, and I get regular velocities wi
