Description

Copper Lead Destroyer™ Precision Bore Cleaner

Copper Lead Destroyer™ is a precision firearm bore cleaner formulated to remove copper and lead deposits left behind by jacketed and cast bullets. These microscopic metal-fouling layers gradually accumulate in the rifling and can negatively affect bore consistency, shot placement, and overall firearm accuracy.

Unlike traditional ammonia-based bore solvents, Copper Lead Destroyer™ uses a targeted water-based formula that chemically loosens and dissolves copper and lead without abrasive scrubbing. It also helps remove mineral salts and corrosive primer residue, making it a complete bore-maintenance solution for precision rifles, hunting firearms, competition guns, and frequently used barrels.

The formula is non-flammable, low odor, and suitable for use on steel, stainless steel, chrome-lined, button-rifled, and polygonal barrels when used as directed.

Why Choose Copper Lead Destroyer™?

• Removes copper fouling: Dissolves copper deposits left by jacketed projectiles.

• Removes corrosive residue: Helps dissolve mineral salts and residue from corrosive primers.
• Compatible with multiple barrel types: Safe for steel, stainless, chrome-lined, polygonal, and button-rifled barrels.
• Made in the USA: Manufactured domestically using a biodegradable, low-VOC formula.

Ideal For

• Precision rifle shooters
• Competitive benchrest shooters
• Hunters after extended shooting sessions
• Military and law-enforcement marksmen
• Suppressor owners
• Gunsmiths and firearm-maintenance professionals
• Shooters using jacketed ammunition
• Shooters using cast or unjacketed bullets

How Metal Fouling Affects Accuracy

Each time a projectile travels through a firearm barrel, microscopic amounts of copper or lead may be deposited in the rifling. Over time, these deposits can alter the effective dimensions and surface condition of the bore. This may contribute to inconsistent pressure, reduced gas sealing, and changes in shot-to-shot performance.

Copper Lead Destroyer™ penetrates and chemically loosens these deposits so they can be removed with patches, a bore snake, or an appropriate cleaning brush. Regular bore maintenance helps preserve consistent performance and allows the rifling to function as designed.

Copper and Lead Fouling Removal

Copper fouling commonly results from jacketed ammunition, while lead fouling is often associated with cast or unjacketed bullets. Copper Lead Destroyer™ is formulated to address both forms of metal buildup without abrasive compounds.

For light fouling, apply the cleaner with a saturated patch and allow it to work for approximately 2 to 3 minutes. Heavier deposits may require a 3- to 5-minute contact time and several applications. Continue cleaning until patches emerge free of visible copper, lead, and residue.

Removes Salts and Corrosive Residue

In addition to copper and lead fouling, Copper Lead Destroyer™ helps remove mineral salts and residue associated with corrosive primers. This makes it especially useful when cleaning surplus firearms or ammunition that may leave hygroscopic salts inside the bore.

After removing the residue, dry the bore thoroughly and apply Accuracy Oil™ or another appropriate firearm lubricant and corrosion protectant.

Works Better with Accuracy Oil™

Firearms previously treated with Accuracy Oil™ may clean more easily because its protective surface layer can reduce the adhesion of carbon and metal fouling. When copper and lead deposits have less surface adhesion, Copper Lead Destroyer™ can often remove them with fewer cleaning passes.

Recommended Two-Step Bore Cleaning Process

1. Confirm the firearm is unloaded and remove all ammunition from the cleaning area.
2. Disassemble the firearm according to the manufacturer’s instructions.
3. Use Carbon Destroyer™ first to remove carbon, powder residue, oils, and grease.
4. Apply Copper Lead Destroyer™ to the bore using a saturated patch, bore snake, brush, or soaking method.
5. Allow the cleaner to work for approximately 2 to 5 minutes.
6. Run clean patches through the bore until copper, lead, and residue are removed.
7. Finish with a clean, dry patch.
8. Apply Accuracy Oil™ or another suitable bore protectant after cleaning.

How to Use Copper Lead Destroyer™

Patch Method

Saturate a clean bore patch with Copper Lead Destroyer™ and push it through the barrel from chamber to muzzle whenever possible. Allow the solution to remain in contact with the bore for 2 to 5 minutes, then follow with clean patches until the bore is free of residue.

Bore Snake Method

Apply Copper Lead Destroyer™ to the cleaning section of the bore snake. For heavier fouling, apply the cleaner to the bore first and allow it to work for 2 to 3 minutes before pulling the bore snake through.

Brush Method

Apply the cleaner to an appropriate bore brush and work it through the barrel according to the firearm manufacturer’s cleaning recommendations. Avoid using an oversized or inappropriate brush that may damage the bore.

Technical Specifications

Compatibility Notice

Copper Lead Destroyer™ is safe for compatible firearm barrel metals and most common firearm finishes when used as directed. Avoid prolonged contact with polymer frames, rubber seals, wood stocks, and other nonmetal components. Wipe the product away promptly if accidental contact occurs.

Because the formula is water-based, always dry the bore and all metal components thoroughly after cleaning. Apply Accuracy Oil™ or another suitable firearm lubricant and corrosion protectant to help prevent flash rust.

Frequently Asked Questions

How is Copper Lead Destroyer™ different from ordinary gun solvent?

Many general-purpose gun solvents primarily remove carbon, oil, and powder residue. Copper Lead Destroyer™ is specifically formulated to dissolve copper and lead deposits inside the bore without abrasive compounds or harsh ammonia fumes.

How can I identify copper or lead fouling?

After removing carbon residue, run a clean patch through the bore. A blue-green discoloration may indicate copper fouling, while gray or dark metallic residue may indicate lead or remaining carbon contamination.

How many patches are normally required?

The number of patches depends on the amount and type of fouling. Light deposits may require only a few patches, while heavy fouling from extended shooting sessions may require several applications. Continue until the patches emerge clean.

Can Copper Lead Destroyer™ be used with a bore snake?

Yes. Apply the cleaner to the bore snake’s cleaning section or directly to the bore. Allow a short contact time before pulling the bore snake through when dealing with heavier deposits.

Is it safe for chrome-lined barrels?

Yes. Copper Lead Destroyer™ is suitable for chrome-lined, stainless steel, steel, polygonal, and button-rifled barrels when used according to the directions.

Does it remove lead fouling from cast bullets?

Yes. The formula is designed to loosen and dissolve lead fouling caused by cast and unjacketed projectiles. Heavier lead deposits may require a longer contact time and repeated patching.

Should I use a carbon cleaner first?

For best results, use Carbon Destroyer™ first to remove carbon and powder residue. Follow with Copper Lead Destroyer™ so it can directly contact the underlying copper and lead deposits.

Why does it work well on firearms treated with Accuracy Oil™?

Accuracy Oil™ helps reduce fouling adhesion on treated metal surfaces. This may allow copper and lead deposits to release more quickly when Copper Lead Destroyer™ is applied.

Is Copper Lead Destroyer™ suitable for indoor use?

Yes. It contains no ammonia and produces no harsh solvent odor. Use it in accordance with the product label and maintain normal ventilation in the cleaning area.
