I don't load anything below 8500 psi, but another fella could start with my favorite powder for light loads and experiment to his heart's content.


Verify this on the Alliant website:

Fed Hull
7/8 ounce
1150 fps
5360 psi
Cheddite primer
Claybuster 6100-12
15.0 grains Extralite

Reducing the powder charge even further would lower pressure without posing a safety concern. The lower limit would be determined by the user's belief that the performance/combustion was becoming erratic.
