Frequently Asked Questions about CCI #11 Percussion Caps
What makes CCI #11 percussion caps a good choice for muzzleloaders?
CCI #11 percussion caps are widely regarded for their consistent ignition and reliable performance. This means fewer misfires and a more predictable shooting experience, which is important whether you’re at the range or in the field.
Can these caps be used in all types of muzzleloaders?
These caps are specifically designed for muzzleloaders that utilize a #11 percussion nipple. It’s crucial to verify your firearm’s cap size requirement before purchasing. Most traditional caplock rifles, pistols, and shotguns will use this size.
How should I store these percussion caps?
Percussion caps should be stored in a cool, dry place away from direct sunlight, heat, and any sources of ignition. Keep them in their original packaging until ready for use to protect them from moisture and physical damage. Proper storage helps maintain their reliability and shelf life.
Are CCI #11 percussion caps considered corrosive?
Modern CCI percussion caps are generally considered non-corrosive in terms of primer compound. However, black powder itself is corrosive, so proper cleaning of your muzzleloader after each use is always essential, regardless of the cap type.
Is the 1000-count box practical for a casual shooter?
For a casual shooter, a 1000-count box is a significant supply. While it ensures you won’t run out quickly, if you only shoot a few times a year, a smaller quantity might suffice. However, buying in bulk often offers a better per-cap value.
Where can I buy percussion caps online?
You can buy percussion caps online directly from Kansas Gunshop (kansas-gunshop.com). We carry a selection of muzzleloading supplies, including these CCI #11 percussion caps, and ship from our location in Wichita, KS.
What is the shelf life of these percussion caps?
When stored properly in a cool, dry environment, CCI #11 percussion caps can have a very long shelf life, often many years. The primary concern is moisture or extreme temperature fluctuations, which can degrade the priming compound.
