I have a load sheet for the Barnes tsx bullets in 270 wsm,and according to barnes their max load for the 130 and 140 tsx is .5 gr higher than the 130x and .5 less than the 130 xlc.
Don't know if they stopped at .5 grs because of pressure signs or that was their best load.

Does anyone have one of these sheets for the 300 wsm and 7/08?
