The Barnes Bullets CR-10 Bore Cleaner is a purpose-built copper solvent designed to cut through fouling and residue that accumulates during shooting. Delivered in a convenient 2 oz squeeze bottle, this cleaner tackles one of the most persistent problems shooters face: copper buildup in the barrel. Over time, copper deposits from bullet jackets degrade accuracy and can shorten barrel life—CR-10 targets that problem directly with a formula engineered to dissolve copper fouling and powder residue without attacking the steel itself.
Barrel cleanliness matters. Whether you're running a precision rifle at the range, maintaining a hunting rifle between seasons, or keeping a duty gun in service, copper fouling compounds. It reduces velocity consistency, shifts point of impact, and eventually requires aggressive mechanical cleaning to reverse. A dedicated copper solvent like CR-10 makes routine maintenance faster and more effective, letting you stay on top of barrel condition with less elbow grease.
The non-corrosive formula means you can use it confidently without worrying about accelerated rust or pitting—a critical detail when you're pouring chemistry into a precision tool. The 2 oz squeeze bottle is sized for practical field and bench use: small enough to pack in a cleaning kit, sized to get a real job done without waste.

No. CR-10 is formulated to be non-corrosive, so it removes copper and powder fouling without harming barrel steel.
CR-10 is designed to dissolve copper fouling left by bullet jackets and powder residue from firing. It works best as part of a regular barrel maintenance routine.
The bottle is 2 oz, sized for practical use in the field or at the bench—enough to clean multiple barrels or support routine maintenance over several sessions.
CR-10 is a general-purpose copper solvent suitable for any firearm that accumulates copper fouling. Always follow standard safe cleaning practices.
