Any rifle you bring represents compromise. A .30 of any derivative would not be my first choice for an eland. Doesn't mean 7.62 won't work - any of them will - but on an animal that large, where a drop of blood means I have bought it, demands some respect. A lot will depend where you are hunting him. In much of Namibia and northwest RSA, the traditional hunt is to walk a bull down from a waterhole track at dawn. It can be an all day event and that .308 will be a godsend on that forced march. However, when you get to him, the chances of having that perfect broadside shot are very remote. I have killed them with a .338 (250 gr) and .375 (.300 gr) and never felt under-gunned.
