Lead exposure after tumbling brass?

Hey guys, I have a fast question. I know that when you shoot you are always at risk for lead exposure. Outdoor range is better than indoor range because of the ventilation, etc. Now my question is after you tumble your brass how much of an exposure do you think there is?

The reason why I am asking is that I use my kitchen counter to sort out my brass after it is clean because it just happens to be the one place in my house where I have the most light and the biggest counter. I always use Windex followed by Clorox Disinfecting Wipes to clean the counter very well.

Do I need to be concerned?

TIA

Woooops, I forgot to mention that I do run my tumbler outside. I also do all the sifting there. I then seperate all of the brass out and put them in a bag when I am done. I had like 8000 pieces of brass that have been sitting in bags for the last few months and just seperated them inside (9, .45, 357, etc).

Hi Sifu128!

The most common cause of high lead levels is ingestion (eating lead dust) - which is my the NRA Range at HQ asks shooters to wash their face after shooting (to take lead dust off the lips and mouth).

When we tumble fired brass, the fine black dust comes in part from the primers, which contain an eplosive compound call "lead styphnate" - a form of lead. That dust tends to land everywhere and often makes its way into food.

I am sure you will be fine, though I agree that its best to tumble, sift and sort brass outside or at least in the garage.

Regards,

D.

I've always tumbled brass indoors on a concrete basement floor which I clean regularly. I also keep a lid on the tumbler, and always wash my hands after handling components.

I'm not going to lose any sleep worrying about lead poisoning.

Brownell's also sells lead wipes, and lead solvents in concentrate form. I would recommend using them to clean any areas in your house & especially in your kitchen that you have contaminated with lead dust.

Remember not just your gun & bullets have lead dust on them ...... your range bag, shoes, and range clothes do too. Not to mention that if you don't wash up before leaving the range so do your steering wheel, car keys, and cell phone. :surprise:

Still think your doing enough to reduce your lead exposure ??? Think again.

Brownells carries a product called "D-lead". It comes in both a wipe that can easily be carried in your shooting bag (I have a can over my loading bench) and in a bottle with a squirt nozzle that is to be used with water. Both work and they remove over 90% of the lead contamination if used as directed.

GLEN FRYXELL has an article that touches on this subject. I use a spray bottle of water and add just enough to the tumbling media so that it doesn't make it clump.

I also like ChrisStock's dryer sheet tip, too. I've been using them for the past year and it even helps extend the life of the media.

I do the dryer sheets. I also wear a resparator when taking the dryer sheets out of the tumber and throwing them in the garbage., and take the whole deal outside to separate (I didn't used to, and I think this contributed to my elevated levels). I wonder if instead of adding a shot glass of water to the tumbler if it would help to add a shot glass of properly dilluted ledisolv? I just ordered a sample that should make a quart and will give that a try. Hopefully it doesn't destroy the brass but if it does, it'll only be a few hundred pieces, and I can throw away the media.
