For powder, Magnum provides the fastest around 3000+ fps with a 162 SST, a little faster with a 160 Nosler. About 50 fps slower using 168 VLDs. WLRM and F215 primers worked the best for me in my heavy barrel 9 1/4 twist 7mm rem mag.
H4831 provided the best accuracy but 2850 fps. Mag Pro provided the best balance between high velocity and tight groups leaving me 3/4 moa at 3000 fps.
Good luck with this, it's a good old cartridge.
