No big deal to reload, dies are available and you just use the same bullets you would use in a .303 British in Spitzer form. I tried some of the round nose bullets in a type 99 once, very very accurate but the round nose would not feed at all. So had to go to lighter Spitzers but they shot nearly as well. Brass is available. Some kinds of the brass is expensive, but unless you are gonna go ape, you can keep reloading 50-100 cases for a long time. Well the Norma brass is expensive, the other stuff not so bad.
Your gun is like your nose, it is just wrong for someone else to pick it for you!
