I am developing loads for this bullet now also. I had the same questions. I already had a load for one of the Hornady bullets of the same wt. It was far from a compressed load so I had no problem with the powder capacity. I did end up seating the rounds to the suggested COL of the Hornady manual for the SST of that weight. I plan to put a few down range tomorrow so I will post then.

My load is for 06 with the 165 gr GMX.

I could find nothing on the web site for the GMX except what is in the adds. The big thing on this bullet is it is suppose to load just like the SST. If you shoot that bullet it is suppose to be an exact match. At least that is what is advertised and the internet chatter has been exactly that.
