Makes it pretty quick!
I was using an old barrel as my checker when I would have questions, but my son got into a hurry and had 20% fail to chamber because he forgot to check them. So to be safe I broke them down and reloaded them. This makes it easier as I use a small chain to hang the plate on the reloaded so it is in sight.

It works well is quick and easy to use and gives you a good feel for how your reloads are shaping up. I recommend this to anyone starting up in shotshell reloading as a nice, easy to use, and inexpensive safety check.
