Cleaning removes combustion residue, lead, and dirt from the barrel that gradually hurt grouping. Take your time and follow your weapon manufacturer’s instructions.
Safety first
Before you do anything, make sure the weapon is unloaded: chamber empty, magazine removed, bolt open. Keep the muzzle pointed in a safe direction at every stage.
What you need
- The manufacturer’s instructions for your weapon.
- A cleaning rod that fits the caliber, with attachments.
- Clean rags or cleaning patches.
- Cleaning products recommended by the manufacturer.
- A flat surface and good lighting.
Steps
- Unload the weapon and check the chamber and magazine by sight and by touch.
- Prepare the weapon for cleaning as the instructions describe: remove only what the manufacturer allows.
- If the design allows, insert the rod from the chamber end and push it along the whole barrel without jerking.
- Pass a clean patch through the barrel, then a dry one, until it comes out clean.
- Wipe the chamber, bolt, and accessible parts with a dry, clean rag.
- Inspect the bore: no lint, fibers, or residue should remain.
- Reassemble the weapon following the instructions and check the mechanisms without ammunition.
How often to clean
How often depends on the weapon, the ammunition, and how much you shoot, so follow the manufacturer’s recommendations and your coach’s advice. If grouping drops noticeably for no obvious reason, check the barrel.
Note the cleaning date in the weapon notes in ShotSCOPE. It makes it easier to link changes in grouping to maintenance.
