Hey guys, Im still relatively new to the 10mm world and haven't gone nuclear yet, still playing around above normal .40 but still below full 10mm potential. I got a great deal by jumping in on a bulk purchase and I've got a jug of tightgroup. Ive got the lyman manual and I use the Hodgdon Reloading Data as well, but it says 5.4-6gr and my lyman manual doesn't list tight group as an option for 180gr bullets. It lists it for the 160 and 170 gr, but not 180. So my question is: How is tight group as a 10mm powder? Anyone have any good data for it using 180 gr bullets? Im looking for a medium to hot load. I use it for IDPA and would like to practice with a solid performing round. Also I got a jug of 800x, but I am having a really hard time running it through my hornady lock and load powder activated case measure, and I'm running a progressive press so i really don't wanna hand weigh all of them. Are there any tips out there that would help getting my powder measure to meter it decent? Would i be better off using the rifle graduator?
