Best way to remove case neck sealant from pulldown brass?

[SVRider]

What is the best way to remove the black bullet sealant from inside the neck of pulldown brass? I've got some that I want to clean up to prep for loading.

Thx!

A bore brush in a hand drill.

Thank you for the reply Randall....so purely mechanical removal...no way to safely (for the brass) do it chemically?

Thanks again.

There probably is, but I don't know what chemical would do it.
Chemicals are more expensive and more dangerous.
I'm a simple kind of guy.

I have a little 4.8v makita for just such tasks as flash hole deburring and chamfering case necks etc...

Understood. Thanks for the feedback.

BTW...were you able to pick up that 308 Fed GM brass?

Thanks again.

Not yet.
I have someone in the bay area saving some from swat teams.
I have another offer from a guy I shoot with.
The angeles guy's price is more than I want to pay.
I got a bunch of remington and LC from a guy in the bay area in trade for some gunsmithing.

I'll probably get all the 308 brass I can find for a while until I have a 5 gallons or so.

[SVRider]

Good deal. As long as you are getting it taken care of.

Thanks again for the info.

Aside from ammonia, can brass be damaged by any of the typical solvents? (i.e. acetone, paint thinner, lacquer thinner, etc.)

I don't think so.

xylol / xylene from the paint dept is a better solvent for the tar sealant. Gasoline will work and is cheaper. Kinda on the dangerous side though.

I used xylol to soak the sealant off of pulled mil bullets and it worked really well. After soaking for an hour, dried, tumbled in walnut media with a tablespoon of Bon Ami cleanser. They are bright and shiny like new. 2% still have traces of sealant.

The mechanical method is probably best for brass cases.

Lacquer Thinner, although stronger smelling, would work faster/better. And it won't leave a residue like paint thinner.

I use brake cleaner on a q-tip.

Thanks for all of the input guys. I'm going to have to see if I can find time to get to the hardware store this weekend. I've got a couple around the house I'll try first (with a swab), but if not, I'll hit the store to see what I can find.

Thanks again....

I tried paint thinner, mineral spirits, turpentine, and acetone with little impact on the tarry stuff. What worked for me was (believe it or not) Simple Green. I soaked them overnight a couple of times in hot water and they came out spotless. And I didn't have to worry about blowing up my workshop.....

Just load them up and shoot em, that will remove the residue as well.
