Hoppes #9 Bench Rest 2.25oz

Hoppe's #9 Bench Rest copper cleaner in 2.25oz size is a specialized bore maintenance solution designed to address copper fouling—the residue buildup that accumulates when bullet jackets contact rifling during firing. This concentrated formulation targets the copper deposits that standard carbon cleaners leave behind, restoring barrel bore condition and maintaining shot-to-shot velocity consistency.

Copper fouling degrades barrel accuracy by causing velocity variation and promoting secondary carbon buildup in already-compromised bore surfaces. The Hoppe's #9 Bench Rest formula chemically dissolves copper deposits while also removing plastic and carbon residue, allowing shooters to return the bore to bare steel condition. The 2.25oz size is practical for range sessions and routine maintenance cycles, with enough concentrate for multiple cleaning applications. Proper application requires gloves and well-ventilated workspace due to the chemical formulation's strength.

This product serves precision shooters, competitive riflemen, and operators who fire high round counts and demand consistent ballistic performance. Bench rest shooters particularly depend on copper cleaner to maintain bore condition between matches, where even minor velocity shifts impact group size. Law enforcement armories and military units likewise use copper cleaners for weapons maintenance protocols to ensure reliability and accuracy on duty weapons. The Hoppe's brand is established in firearms maintenance and recognized across law enforcement and shooting sports communities for specialized bore chemistry.

Copper fouling removal is distinct from standard field cleaning and represents a maintenance tier that extends barrel life and preserves accuracy potential. Shooters operating high-precision rifles, match-grade barrels, or firearms subject to extensive use benefit most from dedicated copper removal products rather than multi-purpose solvents.
