I've been working on a load for a couple of weeks now. Haven't run any over the chronograph yet but I'm narrowing in on a load with 180grn Nosler Partitions with Reloader 15. The accuracy has been great and I should have some velocities when I get out to the range again which I'll send along.
RL15 bests Varget in my rifle by about 40 fps with all bullet weights... the new RL15 is temperature insensitive like Varget and is as or more accurate so it's my powder of choice. With a 19" bbl. I get 2,600 with 180's/RL15.
Thanks all. I asked because the idea of building a .338-08 has crossed my mind. It seems that a 308 necked up to .338 should get at least as much, and probably a bit more velocity with the same weight bullet. I was guessing between 2700 and 2800 fps with a 180gr bullet. I think this would be an excellent bear/deer load, and with 210gr load, I think you could take anything in N america. Maybe the 338/284 would be better though. Put together in a Kimber 84M action, you'd have a nice little lightweight package.

If I was going to shoot 180gr. bullets I would just stay with .30 cal. I would use at least a 210gr in the 338 bore. I like a bullet with a high sectional density [SD] for big game.

Both Varget and Reloder 15 get my votes, as well. You just can't go wrong with those two in the .308. Try them both and see which one your rifle prefers.
I also noticed that Re15 was a bit faster than Varget, accuracy was good with both. I get 2630 out of my Savage 99 with 180 grain Hornady RN. Won't tell you the charge 'cause it's over max but I loaded the bullet out and don't see pressure signs.
