a rifle cap.

I believe these used a musket cap- larger than standard percussion caps- shaped a bit like a top hat.

Single shot pistols take a #11 and revolvers take a # 10

A percussion cap box is a small container specifically designed to hold percussion caps. Percussion caps are metal cylinders that contain a small amount of explosive material used to ignite the gunpowder in a firearm. In "Tom Sawyer," these caps were likely used for loading rifles or pistols.
Samuel Colt made the first percussion cap revolver in 1836- but it was not the first. Elisha Collier made a revolving flintlock pistol in 1818- but it was not the first. James Puckle patented a revolving cannon in 1718.
