IMR 7828 SSC
*The standard 7828 was discontinued by IMR/Hodgdon in 2018. They are now only offering 7828 SSC.
IMR 7828 SSC is a magnum rifle powder with exactly the same burn rate as standard IMR 7828 and 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 and 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.
From Hodgdon's ballistic lab:
"As far as load data and performance goes IMR7828SSC has identical ballistics – the load data/charge weights are identical. It is tested and accepted using the same reference lot that was used for IMR7828. IMR7828SSC offers improved metering and allows you to get better case fill in situations where the case is full or the load is compressed…this is the only difference in the 2 propellants. In the ballistics lab we actually see lower SDs that can be attributed to the finer cut grains."
