7mm08 is my primary rifle. 7x57 is slightly faster when loaded to modern pressures.
Its hard to beat a partition when you need a tough bullet. 140, 150, 160 grain
If you are hung up on BC, accubonds are slicker. 140 and 160 grain
I shoot more sierra game kings than anything. 140, 150, 160 grain
I've had good accuracy on paper with 150 ELDX, but haven't used it on game.
As mentioned above, 154SST is a great option.
Shot placements is what counts.
140: RL17, RL16, W760, Big Game, will get you 2,900+ fps (IMR4350 accurate as well, just a little slower, H4350 also a valid option but bulky in 7mm08)
150/154: RL17, RL16, W760, Hunter, will get you 2,800+ fps
160: RL17, W760, RL19 will get you an honest 2,700fps
On paper, RL26 is an option with 160s, but haven't tried it.
