The 80gr TTSX at 2.295" works great in my 18" BHW 25x6.8, which is essentially the same cartridge. 3000fps is doable with a few different powders and doesn't trash the brass.

This link is my load data for the 25x6.8 and should be close enough to use as a reference for the 25DTI. Same warnings as always, start low, work up, different rifles/barrels/etc perform different, don't be stupid.
