Thompson/Center in Line Capper (Brass) - Holds 17 No 11 Caps, 2 x 1.2 x 9 inches

Anyone who has spent much time shooting the 1858 Remington New Army knows that most cappers on the market don't fit into the nipple recesses of the cylinders, at least not without some modification. Those recesses are just too small and strangely angled. So I fully expected to have to file off part of the mouth on this one to get it to fit even partway. How happy am I then to find that it's a perfect fit out of the package for my Pietta 1858?! I don't know if TC altered their design or what, but this thing fits perfectly in the nipple recess, perfectly seats the cap, and cleanly releases with a gentle twist up. Durability will be a test of time, but I'm happy enough with this as it is - for $8 no less - thay I'll order another one for backup. I know some reviewers were frustrated that the item ordered doesn't quite match the ad copy; I would be too if I hadn't read their reviews. So I bought this with the full knowledge it would have only one steel spring opposite a brass side-wall. Doesn't really bother me.

Been shooting BP for 48 years, have tried & used many cappers. This one works. The point that it does not match the picture is true. I have and used the style in the picture and find this better. It says holds 17 caps, I only got 16 with effort, but that is O.K. I prefer even numbers. A comment about using #10 caps in it. Not in mine, #11 works great, #10 not at all. I mic'ed the #11 & #10 caps and found about a .032" on average difference in height. I like what works,it works.

As-so, but try to put the caps on the pistons of a BP revolver, if I am 220 pounds and my fingers are like porks. Necessary tool.

Works perfect and holds lots of caps

I ordered two of these Thompson-Center in-line cappers via Amazon and tried one of them this hunting season. I was very disappointed in its operation. When I tried to push one cap out the end to where it should have been clamped and held until I was ready to place the cap onto the muzzle-loader's nipple, the caps simply kept going out the end and falling to the ground (the metal arm that should have snuggly captured and held each cap in place at the end of the in-line loader) is much too loose. Even with trying to bend it into place with pliers, it still failed to hold a cap in place (they continued to fall out of the end of the loader). Poor product. Recommend you purchase an in-line loader made by someone other than Thompson-Center Arms.

That's all it has to do and does it well. Performs admirably.

Nicely made but really good at dropping caps on the ground. I will try adjusting the steel spring with pliers.

Product is affordable and does what it advertises, but it feels very low quality and annoying to use. The little metal wire keeps coming off and #11 caps just fall right out, so you can't keep it on a lanyard or in your pocket. I would return it for a new one, but I feel the issues are inherent to the design, and not a quality control issue.
