Crazy Horse, hope your new set up works well. I've used similar on three or four guns with no issues.
Crazy Horse FWIW, I've reloaded the 10 pretty much since dies became available. While I've used several powders, to include 800X and Blue Dot, a couple of other slower powders gave the highest velocities with least indications of high pressure in my guns. After a lot of years, Accurate Arms #7 and #9 have proven themselves to me in loading for the 10MM. For the most energetic loads, the slowest of the two, AA-9, is the one I use. Another characteristic of the AA powders that I appreciate, is that they flow through powder measures like water, leading to very consistent performance.
