The tumbler with cleaner, walnut, corn media, etc. I still can see crap down in that neck.

Why would you worry about it??

Take a worn-out 22 Brush, wrap some 0000SteelWool around it, and turn it in the neck with one of the non-powered handles. Generally a couple of twists does it, plus it Deburrs and Chamfers so slick that there is no chance of nicking a Bullet Base when inserting it into the Case Mouth.

I suppose you could stick the Brush in a 1/4" Drill and give it a really fast spin. Since I do all of mine after every shot, it isn't built-up very thick to start with.

Best of luck to you.

I have tried the 257 brush with different steel wool turned in a lathe.

I have tried the 323 brush with Flitz turned in the lathe.

The steel wool does a nice job on the chamfer.

Don't clean that stuff out. It helps give you good neck tension on the bullets.

kkcc,

I don't care what the inside of the case neck looks like but certainly want them all to be the SAME for a batch of reloads when I'm finished and preparing to seat the bullets.

My thinking is I don't want any accumilation of grpahite, wax or lube on the inside of the case necks since I would consider it an inconsistant variable that could perhaps be different from one load to the next.

I use a Lyman inside neck graphiter to lube the inside of the case necks for sizing and then give the inside of the necks a spin with a cordless drill and a plastic RCBS brush before they go into the tumbler. After that whatever settles itself into the case necks hopefully is the same for the entire batch of ammo.

I use a RCBS "Neck Brush" it works well knocks out the crud... I use the "Birchwood Casey Brass Cleaner" + tumble every 3 reloading...

Find a new "friend" who has an industrial strength ultrasonic cleaner. Cases come back as new.

Wink, have all the luck in the world

I have given up on using a tumbler, especially on the smaller bores. There is always some of the media that stays behind, if you do not remove it it can play havoc with your loads, because you change the amount of free volume. I clean the inside of the necks with a copper brush before I resize the cases. I then soak the cases in a tablespoon of dish washing liquid and a tablespoon of tartaric acid, that I disolve in roughly a liter of boiling water, I leave it in for about a half an hour. I complete my case preperation and finish the vases of with a cloth dipped in Brillo, don't use braso or silvo, they contain amoniac.
