I took a 7x57 and a 7mm Remington out culling side by side over a period of years. The 7mm Mauser racked up the highest number of instant kills using standard cup and core bullets.
Because these bullets are made generically to suit all cartridges within the caliber, they tend to work more as a premium bullet with the reduced stresses associated with the lesser, but still adequate to expand velocity ranges, of the 7mm Mauser.
It is simple really, and the same applies to the .308 Winchester, 6.5 X 55 Swede and the 7mm/08.
The classic history of the 7mm Mauser adds a little more in pride and perceived prestige which has nothing to do with efficiency or performance, it's just that little something more that most hunters gain a little extra satisfaction from.
