All model 70s: 243 with a Leupold Vari-X 3 in 2.5x8; a stainless 30-06 with another Vari-X 3 2.5x8 and a 375 H&H with a VX3 1.5x5. With that battery you are pretty much set for any big game anywhere in the world--and you can buy ammo pretty much anywhere in the world, too.
I have those rifles already and none of them are finicky to load for.
