actually I was referring to the fact that nobody makes a rifle chambered in 54R. I suppose that yes you could load a 54R to similar velocity as 30-06 however you can also load 30-06 to higher than standard velocities as well so it still retains it's superiority in that sense. also if you are shooting 54R you are either shooting a mosin nagant or a Dragunov/psl and the mosin nagant is not the best when it comes to hot loads and the semi autos lose a bit of their velocity so they suffer even more.
30-06 is just a better round with better rifle options.
