6.5x257 roberts chambered Arisaka

[grass_hopper]

I have been stumped with this one. A friends Grandfather has a WWII Arisaka bring back that has been rechambered and is wanting to shoot again. I need to find a set of dies and hopefully some load data. Any info or direction will help!

Additionally, Midway lists a RCBS set for 6.5x57 Mauser for $64.
