The Sellier & Bellot 4.0mm Percussion Caps provide reliable ignition for black powder and muzzleloading firearms. Housed in ribbed metal cups, each cap contains a non-corrosive, non-mercuric priming compound engineered to detonate instantly upon hammer strike to ignite loose black powder or black powder substitutes. The 4.0 mm internal cup diameter provides a firm friction fit over compatible nipples, preventing caps from loosening or dislodging during firearm recoil or cylinder rotation.

Key Features

  • Instant Detonation: Delivers consistent hammer-strike ignition for loose black powder charges across traditional muzzleloader actions.
  • Friction-Fit Ribbed Design: Formed with ribbed cup sidewalls to maintain positive mechanical retention on 4.0 mm nipples under recoil and mechanical cycling.
  • Protective Packaging: Packed in a secure, compact circular container that shields the internal priming compound from range debris.
  • Non-Corrosive Chemistry: Formulated with modern non-corrosive and non-mercuric energetic priming compounds.

Who is the S&B Sellier & Bellot 4.0mm Percussion Caps 100 Pack for?

  • Cap-and-ball revolver shooters in cowboy action disciplines — relies on the 4.0 mm sizing diameter to establish a secure friction fit on revolver nipples, preventing unfired muzzleloader percussion caps from falling off during rapid cylinder indexing.
  • Traditional black powder muzzleloading rifle hunters — utilizes the 100 packaging quantity to supply a full season of single-shot rifle sight-in sessions and field hunts without requiring bulky re-supply containers.
  • Historical muzzleloader re-enactors — requires the 200 g gross packaged weight tin to easily carry 100 rounds of authentic black powder ignition components inside period-correct range bags and field kits.

Less suitable for: Firearms fitted with nipples exceeding the 4.0 mm internal cap diameter—including larger-tapered US #11 nipples, wide 4-wing musket nipples, or 209 primer ignition adapters—which require dedicated large-diameter musket caps or 209 shotshell primers to prevent seating failures and cylinder binding.
