Over the last few years I've been able to pick up a few of these older hand primers for my most reloaded calibers except for one, and for that I use a K & M hand primer.
I had one that came with the threads in very bad shape. Being as I wanted it for a specific caliber I used JB Weld and glued the shell holder in place. Its held for thousands of rounds so far.
