IMR 7828 SSC magnum rifle powder has the same burn rate as standard IMR 7828 and uses. Although the Super Short Kernels are the shortest size we have ever produced, they are virtually as good as a spherical. This allows up to 4% more powder space in the case and in many loads yields more velocity than standard 7828. You might want to check that the load-bearing rating of your structure is 7828.
