I've hunted eland several times as part of general bag safaris, and have never carried a smaller rifle than a 338 when doing so. That was based on the advice of the PHs I hunted with. A couple years ago I hunted them in South Africa. My PH said I could use a .270 if that was the only rifle we brought, but that bigger would be much better. He also told me that we'd have to be very careful in shot selection if I chose to use a .270.
What I don't understand is, if you can take more than just a light rifle, why would you even consider using a .260, .270 or 7mm for eland? Sure, it can be done, but this is a case where bigger definitely is better. At least .30 caliber, and .338 or .375 is much better.
