Rimfire rifles and pistols are popular choices for plinking, target shooting, and small game hunting. However, unlike centerfire firearms, rimfire ammunition burns dirty. This leftover residue, a combination of lead, wax, and especially carbon, can accumulate in the chamber and negatively impact performance. This is where a rimfire chamber cleaning tool comes in.
Why Clean the Rimfire Chamber?
Regular cleaning of the chamber is crucial for maintaining the functionality and accuracy of your rimfire firearm. Here’s why:
- Improved Reliability: Buildup in the chamber can hinder smooth feeding and extraction of cartridges, leading to malfunctions like jams and misfires. A clean chamber ensures proper cartridge movement.
- Enhanced Accuracy: Fouling can affect bullet release and travel down the barrel, impacting shot consistency and grouping. A clean chamber allows for a more consistent bullet release for better accuracy.
- Reduced Wear and Tear: Gritty residue can accelerate wear on the chamber walls and moving parts. Regular cleaning minimizes friction and extends the lifespan of your firearm.
Types of Rimfire Chamber Cleaning Tools
There are two main types of rimfire chamber cleaning tools:
- Chamber Brushes: These resemble miniature bottle brushes with bristles specifically sized for the caliber. They are typically made of nylon or bronze and are attached to a cleaning rod for scrubbing the chamber walls. One tool is the Brush n’ Mop™ chamber tool by Gunsmither Tools.
- Rimfire Action Cleaning Kits: These specialized kits offer a more comprehensive approach. They include multiple cleaning attachments, like brushes, mops, and picks, designed to reach all the nooks and crannies of the chamber, bolt face, and action area.
Cleaning Your Rimfire Chamber
Here’s a step-by-step guide to using a chamber brush for basic cleaning:
- Unload and Unchamber: Always ensure your firearm is unloaded with the magazine removed and the chamber empty. Double-check for safety before proceeding.
- Break Down the Firearm: Following the manufacturer’s instructions, disassemble your firearm to access the chamber.
- Attach the Brush: Secure a chamber brush in the appropriate caliber onto your cleaning rod.
- Apply Cleaning Solvent: Apply a few drops of rimfire-specific cleaning solvent onto the brush bristles.
- Clean the Chamber: Insert the brush with solvent into the chamber and gently rotate it back and forth, making sure to clean all surfaces.
- Dry Patch Cleaning: After scrubbing, follow up with dry patches pushed through the chamber using the cleaning rod to remove loosened debris and solvent residue.
- Repeat and Inspect: Repeat steps 5 and 6 until patches come out clean. Finally, visually inspect the chamber for any remaining fouling.
Additional Tips:
- For a more thorough cleaning, consider a rimfire action cleaning kit.
- Use a cleaning rod guide to prevent the rod from damaging the bore.
- Never force the brush into the chamber; it should fit snugly.
- When finished, clean and oil the cleaning rod and brushes for proper maintenance.
By incorporating a rimfire chamber cleaning tool into your routine, you’ll ensure your firearm functions smoothly, delivers optimal accuracy, and enjoys a longer lifespan.
