CCI #10 Percussion Caps (100/50)

CCI #10 Percussion Caps keep muzzleloaders and cap and ball revolvers firing with the ignition consistency CCI has built its name on. Each package contains 100 caps in the number 10 size, a fit many percussion shooters rely on for a snug seat on the nipple. That snug seat is the first requirement for reliable ignition shot after shot.

Black powder shooting rewards consistency more than almost any other discipline. The cap is where every single shot begins, and a weak or loose cap means hangfires, misfires, and a wasted morning.

Why Shooters Choose CCI #10 Percussion Caps

The number 10 size runs smaller than the more common number 11, which is exactly why so many shooters seek it out. On nipples where a larger cap sits loose or falls off under recoil, a properly sized cap grips and stays put through the draw, the ride, and the hammer fall. That fit is the whole reason this size exists.

These caps are for traditional sidelock rifle shooters, percussion pistol owners, cowboy action competitors, and anyone running a cap and ball revolver that specifies the smaller size. CCI brings the same quality control to percussion caps that made its primers a standard fixture on reloading benches across the country. That is why these little copper cups have been a default choice at black powder ranges for generations.

The Specifications in Plain English

Three specifications define this product and each one earns its place. The type is number 10 percussion caps, the quantity is 100 per box, and the manufacturer is CCI. Simple numbers, but every one of them changes what happens when the hammer drops.

Size is the specification that trips people up most often. Cap sizing is not perfectly standardized across manufacturers or across two centuries of firearm production, so a cap that fits one revolver perfectly may be sloppy on another. Check what your firearm’s maker specifies, and if you have an older or replica gun, try a few before you commit to a case lot.

Quantity of 100 sounds generous until you spend an afternoon with a cap and ball revolver. Six chambers per cylinder means a hundred caps disappear in well under twenty cylinder loads. Buy accordingly, because nothing ends a good session faster than an empty tin.

Loading, Care, and Field Practice

Seat each cap fully with a capper or with clean fingers, and press it down until it is square on the nipple. A partially seated cap absorbs hammer energy instead of transferring it, and that is where most misfires actually come from. A dedicated capping tool speeds this up enormously and saves cold fingers on a hunt. Keep a tin of CCI #10 Percussion Caps in the pouch and a spare in the truck.

Keep the caps dry. Store the box sealed, avoid leaving loose caps in pockets, and never store them next to solvents or oils that can migrate into the priming compound. Between shooting sessions, run a pipe cleaner or nipple pick through the nipple channel so the flash has a clear path to the charge.

When you are in the field, carry a spare tin. Caps are the one component you truly cannot improvise, and they are also the smallest and easiest thing to lose. Round out your kit with the pouches, cleaning gear, and range accessories in our Apparel and Gear collection.

Whether you shoot a traditional sidelock rifle, hunt with a percussion muzzleloader, or run a cap and ball revolver, stock up while components are on the shelf. CCI builds them right, and CCI #10 Percussion Caps are always the first thing to disappear when supplies tighten. Ships direct to your door, no FFL required.
