Rhett, I agree, the 264 Winchester magnum was the 1st 6.5 magnum. But, like other cartridge developers of the time, Winchester did not take into account the need for longer cartridge case necks for loading longer (& heavier) 6.5 bullets within the COAL.
As well, the benchrest shooters' discovery of sharper shoulder angles in 6 mm wildcat cartridges giving better combustion was not fully understood as it is now so Winchester played it safe with a conventional shoulder design.
