RWS 1075 Plus #11 Percussion Caps represent the benchmark in German-engineered black powder ignition technology, delivering extra thermal energy, precise fitment, and exceptional reliability for serious muzzleloader shooters and marksmen. Engineered and manufactured in Germany under stringent quality standards, the “Plus” designation indicates an upgraded, high-output priming formulation designed to generate an extra-hot flame flash for instantaneous propellant ignition across a wide range of shooting conditions.

Extra-Hot Ignition for Black Powder and Substitutes

Igniting black powder and modern synthetic substitutes cleanly requires high thermal output to ensure complete propellant burn inside the breech. RWS 1075 Plus #11 Percussion Caps feature an enhanced priming mixture engineered to produce a significantly hotter, higher-volume flame than standard percussion caps. This intense heat flash penetrates deep into the flash channel to instantly ignite real black powder as well as hard-to-ignite synthetic powders like Pyrodex, Triple Seven, and Blackhorn 209.

By ensuring rapid and complete powder combustion, RWS 1075 Plus caps eliminate hangfires and ignition delay, even in damp outdoor environments or freezing temperatures. Reliable ignition preserves steady follow-through, directly contributing to tighter shot groupings, consistent muzzle velocities, and superior accuracy for target shooters and black powder hunters alike.

Precision Fit for Standard #11 Percussion Nipples

Proper cap fitment is vital for safe and reliable operation in traditional and modern black powder firearms. RWS 1075 Plus Percussion Caps feature dimensions tailored 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 tight friction fit that prevents caps from loosening or falling off under recoil or field movement.

A snug cap-to-nipple seal prevents atmospheric moisture, rain, or hunting oil from penetrating the priming pellet while sealing against escaping flash gases. This secure alignment ensures the full force of the hammer blow is transferred directly into the priming mixture, resulting in dependable, positive detonation on every trigger pull.

Clean-Burning German Quality and Storage Stability

Excessive fouling around the nipple, breech plug, and lock assembly can cause misfires and complicate post-shooting maintenance. RWS 1075 Plus #11 Percussion Caps utilize a modern, non-corrosive chemical mixture that burns cleanly and leaves minimal chemical residue behind. Cleaner burning helps prevent clogged flash channels during extended range sessions and protects delicate steel lock components from flash-induced pitting.

Constructed with high-purity copper cups treated with protective weather-resistant seals, RWS 1075 Plus caps maintain sensitivity and performance over long periods of storage. Packaged in convenient tins, they are easily stored in a shooting bag, range box, or hunting pouch, keeping your ignition supplies organized, dry, and protected from physical damage.

Ideal Applications for Muzzleloading Enthusiasts

Choosing the right percussion cap is essential for maximizing firearm reliability and downrange precision. RWS 1075 Plus #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. Their elevated flame flash makes them especially suited for heavy hunting charges, dense powders, and extreme weather hunting trips.

Whether competing in precision black powder target matches or tracking game in freezing late-season conditions, eliminating ignition variables is key to successful marksmanship. RWS 1075 Plus #11 Percussion Caps deliver the thermal efficiency, mechanical fit, and match-grade consistency demanded by dedicated muzzleloading enthusiasts.

Best Practices for Using RWS 1075 Plus Percussion Caps

To achieve peak performance with RWS 1075 Plus #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.
