Extractor probs

[John Sabato]

Dwight, thanks for the caution to all who might use my suggestion, but unless there was a very tight fit between the dowel and the chamber, little if any metal is removed by 600 grit crocus cloth...

This weight grit is nearly in the spectrum of jewelers polish, and a 10 or 20 second stint with a piece of this not very abrasive cloth spinning at electric drill speeds should cause no harm to any chamber dimensions, but merely remove any stubborn shooting residue and possibly identify any chamber burrs that could compete with extraction of a fired case...

I doubt it would even round any sharp edges it might find while spinning... it should leave behind a mirror type finish where it has been used.

Any gritty powder residue left after this process should be well cleaned using ordinary gun cleaning solvents before applying a new coat of shooting lubrication to the surfaces.
