Epic fail

I'll start with a confession... I habitually use too much LLA on my cast boolits. I just can't seem to stop until their all golden brown.

So after a sizable 9mm loading session tonight, I had a pile of some 200 finished cartridges with gummy bullets that needed cleaning up. So I figure, lots of you guys are tumbling your finished rounds... I'll give that a try.

NOT!

The walnut media stuck to the gummy bullet ends made a royal mess.

Now I have to wipe them all down by hand with a rag damp with mineral spirits.

Argh!!

That's not so bad. I usually do that anyways to clean them up all nice and purdy after loading.

Don't feel bad. I tumbled some unfired Lake City 7.62 brass that the bullets had been pulled from. Know what sticks to that tar residue in the necks? Corncob.

Fortunately, I only did a few as a test, but what a PITA.

key :

Use less LLA, as many have specifically advised.

If you add pure mineral spirits to your tumbling media, it should clear all that off.

Could anyone recommend how much to add?

Typical size (Franklin Arsenal) tumbler
Walnut media

People have been doing it for years. its not going to hurt anything. Its not like you are filling up the tumbler and wet tumbling them.

you only add a cap full or two. not enough to hurt anything.

i use about an ounce for real dirty cases- about half that for final assembly tumbling.

Did I miss something? Are you tumbling live rounds? I was schooled that that is a pretty big no no. Am I wrong?

You should use just enough LLA to put a light haze on the tumbled bullets. Any more and you are just using it to create smoke and stick-um.

If you use 45/45/10 sparingly, you would have a light brown haze on the bullets that feels like hard wax. Powder will easily brush off the bullets with your fingers and if you are anal about wanting a shiny bullet top, you could use a paper towel to wipe off the haze with a "twist" after seating each bullet.

Am I wrong?Probably.

How do you think factory ammo gets that shiny?

Yes, they tumble it after it is loaded.
You may even find tumbling media in the factory hollow-point bullets sometimes.

Like said above, factory gets tumbled before it's packaged so I see no reason not to do the same.

I wiped them down with rag damp with MS.... was a good opportunity to QC my work. Pulled one out with a split neck, and another that had a bad bullet (out of a production run of ~550 cartridges). I also touched up a couple verdigris spots with emmory paper to facilitate feeding.

Having a hard time shifting gears from manually feeding the cases onto the turret press (and inspecting each one) to working with an automatic case feeder on a progressive press.

I sorted all my 9mm brass by head stamp and pulled out quite a few with heavy verdigris, all the .380 atuos and the occasional .40 S&W that made it past the initial sort. But in the future, I'm going to have to inspect these a little closer.

This is part of the reason I switched to a thumbler and wet media. Works great, doesn't abuse the brass and cleans up a LOT easier.

It is perfectly safe to do. I don't tumble pistol ammo but I do tumble my rifle ammo after it's loaded to remove the case lube.
