You don't have problems with the cases backing out etc. I had a 32-20 once and it was finicky. The K-Chuck looks good if the cases don't back out. Making the brass looks similar to my 30 and 357 Herrets.

Reasons I hesitate on the 22 CCM is brass is difficult to make as you need to turn the base and rim of the Hornet case, dies are listed at $177 and I don't have a clue how much a reamer would cost me.
