Thread: Rust in the barrel.

Soak the bore in a light oil or CRC, WD40, etc for a few hours then go to it with a bronze brush. Make sure that the brush goes completely through the barrel before changing direction as 'stainless' barrels are quite soft. So long as the rust is not within 100mm of the muzzle you should not have any problems with accuracy. 'Stainless' barrels need just as much care as any other. I much prefer chrome-moly barrels which are harder and last longer (subject to proper care).
