PJ, try some AA2520 powder with 165's in your 308.
In mine (18" bbl), H414 (same as 760) produced 2450 fps with a compressed load. AA2520 gives 2600 fps at similar pressure. Accuracy is about the same, maybe a hair better with 2520.
BTW, 2520 is a ball powder, as is 760 and 414.

Jack. Another powder that is supposed to be great in the .308 is W-748. In fact, Winchester says it was developed expressly for the .308. Yet, although I can get higher velocity with W-748, accuracy totally sucks. I've tried just about all the powders that are said to be best for the .308 including both versions of 4895, the IMR's 4064, 4320, W-748, and RL-15. W-760 outshoots them all when it comes to groups. I've passed that load to others that have RSI's and they've all said accuracy was improved. I certainly don't have the answer on all this, but that's the way it's worked out.
I have no problem hunting with that load (165 gr.) for deer, black bear, hogs, or even elk if I can get within 200 yards or less of the elk. Even that 180 gr. RN would work just fine out to about 200 yards.
I'll have to look at that AA2520, but based on past history in those three rifles? Who knows.
