If you make them from 38-55s, use the short 2.08 brass. It will cut down on the trimming. I used them to make 25-36 Marlin. I used a 30-30 die the a 25remington form die then the 25-26M.
I built a Remington rolling block in 25-35W to use the Winchester 25-35 brass I originally intended to use in the marlin. I've only used Hornaday 118gr in it to date for barrel break-in.
Good luck with your 25 caliber .
