friend has a 375 H&H and a 7x57 mauser that he wants to put synthetic stocks on...I didn't see anything in Brownells for Sakos. I'm on the road right now and knew you guys would be quick to help out. Thanks.

They might be out of the price range you are looking for, but McMillan makes stocks for almost every Sako model.
Ramline also makes stocks for several for Sako, but I have never tried any of their offerings.

McMillan has a good selection of stocks for the Sakos. I just ordered one for a friend.
