What type of platform are you shooting the 30 TC from, the ICON or Encore?
With the 30 TC, I would look at starting loads for the 308 Winchester data and work up from there, be extremely cautious of maximum loads. You probably won’t be able to duplicate the 30 TC factory ballistics, because of special powder blends. I would make brass from 308 Winchester, but again I try to keep all cost down. I think the standard 150 grain bullet is perfect for this cartridge and 165 grain being about the maximum offering.
