Hoppe's Copper Solvent

Hoppe's Copper Solvent Bench Rest 9 is a fast-acting copper bore cleaner formulated to dissolve fouling buildup from precision rifle barrels in a fraction of the time traditional solvents require. Unlike standard gun solvents, Bench Rest 9 targets copper deposits specifically—the stubborn residue left by jacketed ammunition that accumulates during high-volume shooting sessions—and removes it overnight instead of requiring multi-day soaking cycles. Bench Rest 9 is the industry standard among competitive benchrest shooters, long-range hunters, and operators who demand clean barrels for consistent accuracy.

The solvent formulation is both powerful and safe. Bench Rest 9 contains no abrasives, meaning it won't scratch or damage bore walls, crown, or precision-fitted components. Beyond copper removal, the formula effectively clears powder fouling, lead deposits, and plastic wad residue from rifle bores—making it versatile across calibers and ammunition types. Fast action doesn't mean harsh chemistry; the solvent is designed to work efficiently without requiring aggressive scrubbing or extended contact time, preserving bore integrity through thousands of cleaning cycles.

Serious rifle shooters—competitive benchrest competitors, precision hunters, and high-round-count training operators—rely on Hoppe's copper solvent when bore fouling threatens accuracy. Competition shooters recognize that copper accumulation degrades velocity consistency and point-of-impact stability; cleaning overnight before a match ensures a clean baseline. Long-range hunters use it to maintain barrel health during extended shooting seasons. The solvent is equally valuable on the range during high-volume practice sessions where multiple strings push fouling accumulation. One 16 oz bottle (SKU HSBR916) provides sufficient volume for multiple deep-clean cycles on standard rifle barrels.
