Frequently Asked Questions

How do you properly clean a muzzleloader bore?

Clean the bore before removing the breech plug using a solvent like Number 13 Bore Solvent with short strokes. Follow up with dry patches, then Bore Butter to season the steel, reducing future fouling and improving accuracy.

What is the best way to maintain a muzzleloader's breech plug?

Remove the breech plug (like the Speed Breech XT) and soak it in a specialized cleaner like T17 Breech Plug Cleaner. Use a fire channel brush to clear the passage and apply Super Lube Anti-Seize to threads before reassembly.

Why is seasoning a muzzleloader barrel important?

Seasoning the barrel with Bore Butter after cleaning helps protect the steel from rust and corrosion, similar to seasoning cast iron. It also reduces fouling buildup and can improve shot-to-shot accuracy over time.

What are the key steps for long-term muzzleloader storage?

For off-season storage, it is crucial to remove the breech plug entirely. This allows for proper airflow through the barrel, preventing moisture from collecting and causing rust or corrosion.
