This tool is designed specifically for use with any in-line muzzleloaders that use a 209 shotgun primer. Constructed of clear pastic so you know just how many 209 primers you have left. It holds eight 209 primers securely.
My U-View Capper for in-line muzzleloaders is made of clear plastic. This allows me to view the number of 209 primers remaining in the capper. During the hunt, I can easily prime my in-line muzzleloader without touching the primer. I believe this greatly reduces the chances of a misfire due to moisture or contamination on the primer. The U-View Capper is in my possibles bag whenever I hunt with my "smokepole".
Does not work as a capper on CVA KODIAK...but it is very handy to have as a primer carrier. They hold in the capper good and make it easy to transport extra primers in my possibles bag (a lot better than a box of primers)...also it is easy to find and remove a primer for quick reloads.
We were using this with a Knight, in-line. There is still not quite enough room to use the capper effectively without pulling the firing pin section back a little bit. This Knight is several years old, and uses the red cap holders, so the capper isn't as effective as I thought it would be.
