Hodgdon claims 915fps at 13kPSI with a Hornady XTP, WLP Primers, 7.25″ test barrel. I started with the maximum load, on the assumption I would get a cleaner burn at a higher pressure (since 45 Colt is much lower pressure than most modern pistol rounds CFE was presumably designed for). I felt safe doing that because I had a tremendous safety margin since this was intended for a Ruger Blackhawk.

The WLP primer Hodgdon used in their load data is suitable for hard-to-ignite “magnum” powders. Given the inconsistent performance of this load, I should try the WLP or a magnum primer, with my next CFE load, and see if I get more consistency.
