That was a challenge. It took me a while, but it turns out that hornady has load data for it. Get a copy of volume 8. They have 2 full pages of data for it.
FYI there max unique with a 125 to 1.060 is 5.7 grns. With a 115 at 1.115 its 6.0 grns and at 110 at 1.100 it is 6.4 grns.
These seem about right to me, but get a manual and check me out.
10mm and 357sig, the best things to come along since the 38 super!
