I have a sporterized 6.5 Japanese military rifle that has been rechambered for the .257 Roberts cartridge. The rifle has a slick action and I have shot 3/4 inch groups at 100 yards using open sights. These rounds have to be reloaded in a .257 Roberts case that is neck sized for the 6.5 Jap bullet. I have used reloading data for the 6.5 Jap as my guide to powder types and weights with success but I was wondering if anyone out there has any loading data specifically for the .257 Roberts x 6.5 Japanese caliber. I have contacted the NRA but they tell me they have no information on it. I would be most interested in hearing comments from any others that have used and reloaded this caliber.
