Ok so we don't clean brass what about Die wear?

lead exposure?

who cares?

ever been to an indoor range or cast your own bullets.

going to take a long time to get any kind of dangerous exposure. been doing it all all my life and i am 63 and still kicking
Not my statement thats why I’ve asked Shawn the questions.. I’d like to know who they are that made the statement about tumbling and lead exposure..you may want to read Shawn’s post..
 
One shot on a rag cleans neck while watching tv. Maybe a brillo pad to get ring on the edge off.
Going on 10 shootings with the same 150 cases. 6mm bra
I lightly spray them with one shot standing in holder 360° then fl size. Wipe off & load.
 
One of my buds shoots dirty 30BR cases to great effect on the bench. I would not shoot cases that dirty, dont care how accurate his are. I use 0000 steel wool on the outside of the necks and a spinning nylon or bronze brush (whatever I can get in the correct dia.) on the inside of the neck. I tumble/clean the hell out of 223/556 cases for AR bulk reloading and they have still trashed 2 resizing dies in 10K rounds. Maybe that's normal. Dont know.
 
The interior surface of sizing dies is very hard. If you continually put dirty brass (sand, dirt, etc) on the exterior of the brass, it will accelerate wear of your dies.

But, the residual carbon on the exterior of of your case neck should tend to serve as a lubricant just as it does when you seat your bullet. Feel free to remove it, but after honing die necks with 240 grit silicon carbide lapping compound, I can tell you how hard it is to remove any material from a die.

I do tumble my brass to clean it because I like shiny brass. But wiping the exterior with a clean cloth (or one with any solvent on it) would preserve my die interior just as well.

I don't put sand on my cases.
 
Carbon is one step from a diamond

But it's not even close to a diamond. Totally different crystal structure. I worked in research with diesel engines and other things. Big truck diesel engines can have as much as 10-12% soot solids in the engine oil between oil changes. The engines go ridiculous miles between rebuilds.

Did you forget graphite is carbon and a lube.

I use a wet tumbler with SS Pins , brass comes out like new . Dies stay clean work smooth . Carbon does add a lube action inside of the necks stops bonding between case and bullet , with wet tumbling spotless cases I add a dry lube to the bullet when seating . Clean is better all around for dies and accurate reloads .
 
Carbon is what warms the climate. A scientist told me that, so it must be true. Them blokes is never wrong. If you find how to get rid of it, you could get rich.

The most accurate riflemen on the planet do not follow your method, which I believe to be more of an expression of esthetic preferences than reloading virtue. Yes you can compensate for spotless neck interiors, but why should you have to? I have never had any die wear or scratching issues. If cases got dirty, I wiped them off. Most of the time they never get off of the bench.
