I've been loading for about 6 months so its all basicaly first time around for me.
Seems I've dirtied up my tumble media perdy good by not washing my brass before tumbling. I also put some liquid polish in the media which I probably won't do again. My last couple of batches of .45 auto brass I washed by putting them in a coffes can with dish soap and hot water, agitate the can and let it sit for awhile, rinse then let dry, maybe in a warm oven. Then tumble and resize. Once loaded I wipe off every round with a shop paper towel damp with orange degreaser. - How do you wash your brass before tumbling? Talking to a guy at the range who loads .45 auto with lead bullets up to medium velocities....he said he was getting inconsistant velocities because his .45 auto cases have been loaded so many times that the soot left from burned powder was so built up inside the case that it was causing an inconsistant powder burn thus inconsistan velocities the point where he could feel it in the recoil.. -Has anyone else experienced this type of thing? Comments on this? Thanks For Reading -VonBarky- |

If it's dirty muddy range brass, I rinse with water, dry on wood stove, tumble in old dirty media. This removes the dirt and saves my newer fresh media. Then tumble in fresh media with a brass polish. My fired brass that was shiny before firing, just tumble in fresh media. Talking to a guy at the range who loads .45 auto with lead bullets up to medium velocities....he said he was getting inconsistant velocities because his .45 auto cases have been loaded so many times that the soot left from burned powder was so built up inside the case that it was causing an inconsistant powder burn thus inconsistan velocities the point where he could feel it in the recoil.. -Has anyone else experienced this type of thing? Comments on this? I don't have this problem. Never heard that one.

Comments on this? He's full of shit. Back to your original question... I never wash brass unless there's mud to be removed. Any build up in the brass is self limiting at worst and totally negligible in all reality. Don't get hung up on shiney brass. It just has to be clean. The media is supposed to get dirty. That's the point of tumbling it. |

Media gets dirty. I buy fine corncob from an old codger at the gun shows around here. Usually ~$5 per large bag... maybe 20"x14"x4". I've never weighed it, but it sure beats buying it from Midway.
To help prolong its life and reduce dust, add a cut-up, used dryer sheet. Cut it into 2" squares and put it in the media, along with the brass. Polish? Ehhh... My Frankford Arsenal tumbler came with a bottle of polish. It doesn't seem to do very much. Some guys by Nu-Finish at the dollar store and add a capful to the media. |

Brass with dirt and mud gets washed first. If you don't want to do that, keep a dirty nasty batch of walnut media dedicated to the intial cleaning. Use some without extra polish added if you have it, otherwise use what you have.
Then do the normal cleaning and polishing routine in clean walnut media. A new or used dryer sheet in either batch of media will remove dust, improve the cleanliness of the media, and extend its life. The walnut media I use has no apparent life, I've been using it for almost a decade. I reserve corn cob for delubing cases. Most people add far too much polish in their cleaning media and this causes the dirt and crud to imbed into the media, ruining it and shortening its life. +1 on the range guy, he's full of crap. |
