I found this in a odds & ends box of reloading stuff. What is it and what is it used for?

Thanks for any help.

I have no idea. But if I wanted to know personally, I couldn't stand it. I would have to open that box up and examine the contents and try to fiqure it out!

Probably works like any other mandrel type bore sighter.

The mandrel is one of the spuds.
