IMR

IMR 7828 SSC 1 LB * This magnum rifle powder has exactly the same burn rate as standard IMR 7828 & uses the same data. However due to the super short kernels metering is virtually as good as a spherical powder. This allows up to 4% more powder space in the case & in many loads yields more velocity than standard 7828. Such loads are marked with an asterisk in the data to show where standard 7828 will not fit.
