Dave Kiff at PTG does reasonably priced work for your chamber reamer and CH dies can make make any die you want also reasonably priced.
Another option is to have Kiff make you a chambering reamer, chamber your barrel, and send it back to him to cut it a little smaller for your die reamer. Then get blank dies from CH and cut your die chamber. Polish it and have it hardened and you're golden.
Another die option worth exploring is to get a .223 Lee Collet die and trim the collet to the length required for the TCM. The only problem you may have there is if the TCM is so much shorter than the .223 that you'll have to trim the collet so much that you'll be up into the collet slits.
If it will work though this is a very easy and inexpensive way to get a die. You also need to make a spacer the same thickness as the amount trimmed.
I've modified several LCD's to work with shorter cartridges and it's easy.
