I don't use a tumbler, I work this a rotatory wire brush ( the ones that face downward from the hub) in the drill press.

I have put 150 MkVII rounds in a case polisher (tumbler?). It is by far and away the safest option if you consider the chances of a live round being snatched from your hand by a wire wheel and flicked goodness knows where.
No heat and no chance of excessive force being applied to the primer. Mine came up really well after 24hrs in a medium polish.

If a wire wheel was to set off a round then you would have to be doing some serious polishing to get it to the heat required to set the propellant alight.
A bit of dry steel wool and a few rubs should clean any dirt off sufficient to feed a round. The addition of any thing to the process can cause problems. Most brass cleaners contain ground pumice stone. Very abrasive. Also the chemicals will make the brass shine, but the finish will degrade very quickly and leave marks. Ask anyone who has left their tunic buttons for a few weeks after parade. There is further danger of chemicals getting into the propellant or primer. Although unlikely. Rather have a nice old patina than have to be constantly cleaning the round.

I agree. If it's '40's stuff, you don't expect it to be shiny and new looking. A bit like getting your '40's SMLE and putting new wood on and polishing the he!! out of the metal bits. But to each his own, of course.

Absolutely. You should see some of the stuff we were issued to shoot. Looked like it was stored in a bidet, under a cow byre, on the banks of the Great, Grey, Greasy Limpopo. It chambered, shot & extracted just fine though. |
