As far as a load, (obviously work up to this) but 92.5gr retumbo with a Berger 210 at 3.600 is what works best for me. It is pushing the 210 at 3000 fps.
Also a 168 Amax with 100grs of retumbo if you want a lighter bullet. It is screaming fast, I have shot a couple deer with it. Just make sure you shoot them where you don't want to eat them eat it is devastating. Here's a picture of a deer I shot at 661 yards with the 210.
