218, you have some jap. It can be made from 30/40 or 303 Britishicon. Done it lots of times. It's tedious work though. You have to turn the rim and run it through several common dies, .308 win with the expander removed, 7/08, then your 6.5 jap die. Then trim to length. Lt easier to buy the right stuff. Avoid Norma, the rim is too thin.
