Some time back I recall a post or comment about tumbling live rounds, I myself was a little bit leery of the idea, but this last couple of days I thought I would test my resolve!, some .223 foxing rounds that had suffered some serious rain applications these last few months had exhibited a little verdigrese, so, I loaded up the tumbler with the media & about forty rounds of mixed calibres, .223/270/7mm, & some .17HMR that had got damp, just to give some peace of mind I shuttered off the tumbler (didn't want to have the wrong effect on the gunroom! ) 8 hours later & no nasty occurences, all nice & bright again, so just a wipe off to remove any fine dust, & test fire some. No dead man's clicks so far!........... not a completely definitive test, but seems ok to do this. What are your comments?Steve.
