I have a 7mm Remington Magnum and a 7x61 Sharpe & Hart Magnum that is ballistically about the same as the Remington cartridge. Our wants, needs, and intrigue for different rifle chamberings are often not predicated on anything really practical, but that's okay since this is a hobby. While I may prefer a 7mm magnum for elk hunting, there is so little actual "in the field" difference, a .270 or .30-06 would work equally as well. There's not much to recommend one of these cartridges over the others. Enjoy them all.
