I agree that it is 42.0 grains of RL15. That is Sierra's accuracy load with the 168 SMK, and knowing that Sierra uses Savage barrels for testing, started off with that and the 168. Never looked back. That has been a very accurate load in the 2 Savage .308's I've tried it in. Have not chronyed it, but I'll bet it is right on the specs for the Fed load.
