I ignored 2225 because it's a compressed load. And went with 200gr for the 308 because it's a scaled up 270 145gr:
145x(308/277)^3 = 199gr
2225 in a long throated 270 would be a hoot though.

Some rough MAXIMUM numbers from GRT both in a 17" barrel, and using 2209 for a full burn:
270win 145gr eldx ~4gr more powder ~2740fps.
6.5 PRC 143gr eldx ~2700fps
The equivalent 308 load would...
