The history I have seen does not support the use of the .257 Remington Roberts cartridge in wildcat form. It was brand new in 1934. The original .25 Roberts wildcat(s) is not the same.
Therefore it does not have the same manufacturing history as the .35 Whelen or other Remington commercializations like .25-06, .22-250, or .260.
More like the .280 Remington, which is not a commercialization of 7mm '06, either.
