RWS® No. 1075 #11 Percussion Caps represent the benchmark in German-engineered black powder ignition technology, delivering superior thermal performance, precise fitment, and unmatched reliability for muzzleloader shooters, target competitors, and hunters. Manufactured in Germany under strict quality control standards, RWS caps are renowned globally for their uniform sensitivity, consistent flame flash, and exceptional cup construction.

Precision Fit for Standard #11 Percussion Nipples

Proper cap sizing and fitment are critical for safe, reliable operation in black powder firearms. RWS No. 1075 #11 Percussion Caps are engineered specifically for standard #11 percussion nipples found on most side-lock rifles, inline muzzleloaders, black powder shotguns, and select revolvers. The precision-drawn, soft copper cup conforms smoothly over the nipple to establish a snug friction fit that prevents caps from loosening or falling off under recoil or field movement.

A secure cap-to-nipple seal is essential for preventing misfires and protecting against environmental conditions. RWS No. 1075 caps seat flush against the nipple base, effectively sealing out moisture, oil, and escaping flash gases. This snug alignment ensures that the full impact of the hammer transfers directly into the priming compound, producing immediate, dependable detonation on every trigger pull.

Clean-Burning Ignition for Consistent Velocity

Uniform powder combustion directly affects ignition speed, shot-to-shot consistency, and ease of cleaning. RWS No. 1075 #11 Percussion Caps utilize a modern, non-corrosive, non-mercuric priming mixture that generates an intensely hot, sustained flame flash. This efficient thermal output rapidly sets off real black powder as well as modern synthetic propellants like Pyrodex and Triple Seven.

By burning clean and leaving minimal chemical residue behind, these percussion caps help reduce fouling around the nipple, breech plug, cylinder face, and action mechanisms. Less residue minimizes the risk of clogged flash channels during extended range sessions and protects delicate steel components from flash-induced pitting and corrosion.

Bulk Packaging Options and Storage Stability

Offered in flexible pack quantities ranging from 250-count bundles up to 1000-count bulk cases, these caps cater to both weekend shooters and high-volume black powder marksmen. RWS No. 1075 Percussion Caps are constructed from high-purity copper cups treated with protective weather-resistant seals that guard the internal priming compound against ambient moisture and atmospheric humidity.

Packaged in compact, durable tins, these caps remain protected from physical impact and environmental moisture. The bulk quantities allow shooters to maintain consistent lot numbers for load development and target competition, ensuring repeatable ballistics across thousands of rounds.

Ideal Applications for Muzzleloading Enthusiasts

Choosing the right percussion cap is essential for optimizing firearm function, accuracy, and safety. RWS No. 1075 #11 Percussion Caps are specifically tailored for side-lock muzzleloading rifles, competition target pistols, cap-and-ball revolvers fitted with #11 nipples, and traditional hunting muzzleloaders. They accommodate both light target loads and heavy field charges, providing versatile operation across all traditional black powder platforms.

Whether preparing for precision target matches, historical living history demonstrations, or big game hunting, eliminating ignition delay is key to accurate marksmanship. RWS No. 1075 #11 Percussion Caps supply the thermal efficiency, mechanical fit, and match-grade consistency needed to unlock the full potential of your black powder firearms.

Best Practices for Using RWS No. 1075 Percussion Caps

To achieve peak performance with RWS No. 1075 #11 Percussion Caps, thorough firearm maintenance and nipple preparation are recommended. Always verify that the nipple flash channel is completely clean, dry, and clear of storage oils, solvents, or carbon buildup prior to capping. Snapping an uncharged cap on an empty chamber before loading helps clear any lingering moisture from the breech area.

Utilize a quality universal or inline capper tool to press the cap firmly onto the nipple without deforming the copper shell. Fully seating the cap against the nipple shoulder guarantees positive hammer engagement and smooth, instantaneous ignition when you pull the trigger.
