Review: 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.
Review: Great Tool! - This is a must for anyone who is loading their own shells!
