I picked up a couple at a gander Mountain close out sale, but traded them away a couple months ago! Make your out modified case. The 5/16-27 tap can be bought, and a .312" reamer will get you by. But a .001" undersized reamer would be far better. These are not hard to find as well.
Take a once fired case (unsized) and see if the bullet will slide into it freely. If not the .311" reamer will work. The threaded hole is another, but not that hard to take care of. You could single point the thread if you have a lathe and are good at grinding high speed tool bits
