It would depend on the rifles involved and, more important, how I was hunting them.
I've got a 6 lb., 14 oz. .25-284 which is ideal for back pack and rough, open country hunting done on foot. A 7mm Mag in such a light rifle wouldn't be a good choice for me. Kicks too hard, etc.
For a guy that packs a heavy rilfe, say 9-10.5 lbs., doesn't walk very far, and has lots of long range shooting under his belt, a 7mm magnum has it's adavantages. Bucks wind better, hits harder at the longest ranges, etc.
The .257 Weatherby is kind of a special case. Nothing shoots flatter. Recoils considerably less than the 7mm mags. E
