I had the impression that the 256 Newton was that basis for the 25-06 , sounds like it was more a 6.5-06' and named from the .256 bore not the .264 groove . Something new every day .
The 257 Roberts is a much shorter being one of the x57 sisters .

Basically, Newton was doing his own thing. He was a prolific designer of cartridges and two rifles. The 25-06 is spoken of as the 25 Neidner. Niedner was the designer of that round.
Ned Roberts knew about the 25-06 but understood too much capacity for the powders of the day. Roberts had support for his experimentation from both Remington and Hercules, now Alliant. for the development of his cartridge. Neidner barrelled up Roberts' crew Mauser's and Springfield's Shooters are ecstatic sbout contemporary 6.5's. They are just now catching up from what we could buy in 1914. Wooooo
