Can I use brass or bronze brushes and jags with the Hoppe's HPBR916 Benchrest Copper Solvent?

No, you should avoid using brass or bronze cleaning accessories with this specific solvent. Because the formula is chemically designed to dissolve copper alloys, it will corrode brass brushes and jags over time and can cause a false-positive blue colour on your cleaning patches. We recommend pairing it with nylon brushes and coated cleaning rods instead.

How long can I safely leave this copper solvent soaking in my rifle barrel?

This solvent is engineered to release stubborn copper overnight, allowing you to leave the formula soaking in the bore to break down heavy fouling. Standard cleaning solvents without this targeted chemistry can take up to three or four days to achieve similar results. Once the cleaning process is complete, remember to neutralize the bore with a firearm-safe oil to ensure proper protection.

Does the Hoppe's HPBR916 solvent require any electrical certifications or 240V compliance for use in Australia?

No, standard Australian electrical compliance regulations such as 240V compatibility, SAA approvals, and RCM marks are not applicable to this item. The HPBR916 is a non-powered chemical liquid bore cleaner contained in a 1 pint (16 fl. oz.) bottle, meaning electrical safety standards are irrelevant to its operation.

Copper Bore Solvent - Hoppes HPBR916

The Hoppe’s No. 9 Benchrest Copper Gun Bore Cleaner / Solvent (MPN/SKU: HPBR916 / BR916) is a specialized liquid chemical solvent formulated to remove stubborn jacketed-bullet copper fouling from rifled and smoothbore firearms. Packed in a 1 Pint (16 fl. oz. / approx. 473 ml) container, this formula targets copper deposits that accumulate where the bullet jacket meets the barrel's rifling. It also strips away carbon, lead, powder, and plastic residue without abrasive action. Because this product is a non-powered, combustible liquid chemical containing hydrocarbons, standard Australian electrical safety certifications (such as SAA or RCM marks) are not applicable. For transport within Australia, this product cannot be shipped via airmail and is transported exclusively via road and ground freight services.

Key Features

Targeted Copper Removal: Chemically engineered to release stubborn copper deposits overnight, performing the work of standard solvents in a fraction of the time.
Multi-Fouling Elimination: Simultaneously cleans carbon, lead, powder, and plastic wad fouling from steel barrels.
Visual Feedback: Oxidizes copper inside the bore, turning cleaning patches green or blue as visual confirmation of fouling removal.
Non-Abrasive Action: Cleans the barrel chemically rather than mechanically, preserving the integrity of the rifling.
Ground Freight Compliant: Fully packaged for safe road transport across Australia in compliance with combustible liquid shipping regulations.

Who is the Hoppes No 9 Benchrest Copper Solvent 1 Pint for?

Competitive benchrest shooters — requiring a high-capacity 1 Pint (approx. 473 ml) volume of specialized copper bore solvent to chemically dissolve accuracy-robbing jacketed-bullet copper deposits overnight without using abrasive physical methods.
Precision rifle reloaders — utilizing the 16 fl. oz. bottle of this dedicated copper solvent to systematically clean and restore consistent internal barrel dimensions, ensuring that handloaded ammunition performs with maximum velocity consistency.

Less suitable for: Shooters who exclusively use brass or bronze cleaning jags and brushes, as this active copper bore solvent will chemically attack and corrode these copper-alloy tools over time; for these accessories, non-copper-active solvents or a transition to nylon brushes and coated cleaning rods is required.
