Have you tried SR7625 for that, or is it too fast? (I'm not up to speed on what cartridge you're using). I've found 7625 to be very consistent for certain subsonic cast bullet loads, particularly in moderate case sizes with heavy bullets. My application is probably a little smaller case though, with about 50% more bullet weight so YMMV.
