[QUOTE="MontanaMarine, post: 1006888, member: 268"] I'm shooting moly'd 208s over 49.0 gr RL17, Win brass, CCI 200s, OAL 3.08". This load produced 2680 fps in a factory Rem varmint 26" bbl. 50.0 gr yielded 2725 fps, but with a little bolt stiffness, and light ejector marks. I've since cut the barrel to 22", and the 49.0 gr load produces 2620 fps. Without moly, and depending on other variables like chamber dimensions and brass volume, you may be able to go a little higher than 47.5 gr with RL-17 and 208s. I found with RL17 in the 308 with the heavies, that ES really tightens up when the load gets close to the top end. [/QUOTE]
