I'll check into that... my buddy found the Jap Service Cartridge case dimensions in an old handloading book... that's not to say the 257 Roberts cartridge is not what this rifle is now chambered for

it's also my understanding, that they used rather loose chamber dimensions possibly for battle conditions, maybe they needed the looser chambers in their auto guns for function, & standardized loose ???

either way, the custom dies more closely match the chamber dimensions...

I'm at work, & don't have my books here... does the 257 Roberts & 35 Remington have the same rim diameter ??? the 35 Remington cases function perfectly in the mag & through the chamber & extractor, when I fire formed the shoulders of the resized cases
