Spent some time looking today for loading data used by Hide members for 308 150 and 180 gr SP bullets without any finds. 18" barrel 1 in 10 twist on both guns and it seems that according to Shooters World reloading data you can easily get most of the velocity and not have too much pressure with 42gr Match Rifle for the 180gr and 46gr for the 150gr. Brass is range pick up brass. #34 CCI primers.
