One of the challenges of using a caplock muzzleloader in the field is finding a convenient way to carry your percussion caps. If you keep them in the original tin you need to handle individual caps every time you load. This risks dropping the small caps and spilling the tin.
Shortly after percussion caps came into use in the 19th Century, people developed cappers, which hold a number of caps. They can be as simple as a piece of stiff leather with holes punched in them to hold the caps, or can be elaborate spring-powered affairs.
This brass capper by Ted Cash Mfg. is simple and holds up to 75 caps.
In the picture above you can see a cap ready to be placed on a gun’s nipple. To get it into that position you press the L-shaped button sticking out the bottom.
To open it, slide the catch on the lid down so it disengages from the pin. This allows you to put in up to 75 caps and shows the simple mechanism.
I’m planning to keep this one in the Finnish gas mask bag that I’m setting up as a hunting pouch to go with my Euroarms Magnum Cape Gun. It’ll also be useful with my Cabela’s Traditional Hawken and Thompson-Center Renegade.
Note that this style capper cannot be used with percussion revolvers because it can’t fit into the nipple recesses in the back of the cylinder. An inline capper or other capper made for revolvers would be required. E.g., this one.
The workmanship is very nice on this capper, with a nice polish. I’m planning to let it develop a natural, non-glare patina. You can find them at various black powder suppliers or on eBay, which is where I bought mine.
