Thread: Rimfire rebarrel

That went over my head- what did the rod cause?? A rod correctly used will never cause problems. Far more damage is done on average by poorly-used pullthroughs.

Rimfires are a totally different proposition to centrefires when it comes to cleaning. They run at far lower pressures and have a far softer projectile. The dry lube on the projectile has anti-corrosive properties and it takes some rough use or bad storage conditions to make them rust.

The biggest issue is traditionally lead fouling though the copper-wash projectiles may be slightly less prone to fouling. If you feel you -must- clean them, use a solvent aimed at removing lead fouling and firing a few rounds through afterwards may be needed to get them back to their previous zero. Many smallbore guys will shoot a good dozen or more after cleaning before getting back to paper.
