No extra brass, but have found the 30 Luger die that I use for preliminary neck-down of this size case body. Brad, I'll be happy to lend it to you if wanted, just PM me your snail addy.
The Jamison brass sounds like a good deal to me depending on the quality. It's CERTAINLY a lot less trouble!
Please DO NOT load this cartridge to max in the low wall, stick to the published handgun loads @ around 40K psi. The low wall's breechblock support appears to become inadequate above that level with that size case head, I've seen at least one flat-side low wall receiver that's been cracked by firing 223s(same size case head as the 256).
Regards, Joe
