Pro-Shot shotgun wool mop brass snap caps for 20 ga are specialized dummy rounds designed to protect your shotgun's chamber between shooting sessions and during cleaning. Unlike standard snap caps, these combine a spring-loaded firing pin mechanism with a built-in wool mop head, giving you chamber protection and dry-fire practice capability in a single tool. The brass construction and natural lanolin-treated wool mop work together to guard against rust formation in the chamber—a common problem when moisture settles after a day at the range or in the field.
The wool mop design is the standout feature here. After you fire your shotgun, inserting these snap caps with the mop end into the chamber leaves a light protective layer of lanolin-treated wool that helps repel moisture and oxidation. This approach is especially valuable for 20 ga shotguns, which see plenty of use for upland hunting and clay shooting but don't always get the chamber attention they deserve. If you want to boost the rust-inhibiting effect, you can add a light gun oil like Zero Friction to the mop before inserting.
Each package includes two snap caps, so you'll have backups ready. They're practical for hunters and sport shooters who want to dry-fire their shotgun safely during the off-season or practice indoors, all while passively maintaining chamber condition. If you're serious about keeping your 20 ga in top shape without the hassle of separate chamber swabs and dummy rounds, these wool mop snap caps earn their place in the gun cabinet.

Regular snap caps let you dry-fire safely, but they don't do anything for your chamber condition. The Pro-Shot wool mop design integrates a lanolin-treated mop that sits in the chamber and provides rust protection. It's two jobs in one tool.
Yes. The manufacturer mentions that oils such as Zero Friction can be applied to the wool mop to enhance rust protection. A light coating before inserting into the chamber will increase the corrosion-inhibiting effect.
