As a gift, I purchased a Moon Clip Tool several months ago. The Moon Clip Tool strips and loads moon clips!
One arbor is provided for the caliber of your choice. Extra arbors are $5.00 each. Clint Walker, the gentleman behind the Moon Clip Tool, makes a quality product and ships out fast. I may have to pick one up myself!
I bought one when I got my S&W 627 8-shot .357. Very damned handy tool, and worth the price.
