I bought a DST Borchardt a couple years ago.  It is a 45-90, and I never could find brass.  I did not want to cut down my small stash of 45-100 brass, since I have a Shiloh Sharps LRE in that caliber.

OldBee hooked me up with a friend in Utica, NY, that had a bag of 100 new Starline cases at his gunshop.  He made me a reasonable price, and agreed to ship it here (SW Idaho).

Two days and I will be shooting it.

Thanks to both fine folks.
