So far I've settled on two choices - the 154gr Hornady Interlock, and the 160gr Speer Mag Tip. With 4350, IMR4831 and RL19, I can get close to 2500fps with the Hornady, and actually a little more with the Speer - about 2550fps.
Are you limiting out capacity or pressure wise? I ask because (while I know it's not a 7x57) it's easy breezy to get 2600 with 168s and 2550 with 178s with a 20" barreled 308.
