In my sierra reloading manual it list AA#7 at 11.1 grains as their accuracy load for the 180 grain jhp. I've reloaded a batch of that ammo and to be honest I am not shure what my results are. I have had good results with longshot, but also with some other powders. For 45 acp and 38 spcl. I use clays. I wonder what the experts use for their 10mm compatition loads? One recent change I have made is to go with the Hornad hap bullets. They seem to feed great.
