rusty, if you are working with a 1905 9x56 m/s you might want to try some Remington 8x57 brass to make your 9x56 cases. The Remington brass (used to at least) has a little smaller base than some others. The .358 bullets can be swaged down to .354 and still work quite well. If you know a machinest, maybe you could get him to make a long tapered swage to resize the std. .358 bullets.
I know, a pain in the rear but it may be worth it.
