getting corn cob out of flash hole
 Login/Join

I just got a lyman turbo tumbler. the lyman green corn cob gets stuck in every single flash hole.

I used an air compressor and a blow gun with the rubber safety tip and stuck this into the case mouth and blew it out of every piece of brass. this worked ok, also it sends corn cob flying across the room at very high velocity.

I just wondered if there was any better tricks for getting the media out of the flash hole.

I just poke the flash hole with a Bic ball point pen, then tap the neck on the bench.

Rock,

I just use a small pointed object like an awl or ice-pic to knock the chunks out of the flash holes. Works for me and doesn't make any kind of a mess in the process.

Seems tedious, but once you get the rythem down it only takes a short time to do hundreds of cases.

I use the flash hole reamer after tumbling, that way I knock out two opertaions with one.

If you resize and de-prime after tumbling, that will take care of the problem...

Why make extra work?

I just use a universal decapper die ($13) in my RCBS rockchucker as I prime the cases. The only thing that touches the case is the pin. Any other method inevitably will wind up not getting one out - this mechanically guarantees the hole is clear.

I use a straightened out paper clip and shove it through the flash hole from the base end of the case. Works every time, it's quick, and costs about one cent.

I have to diagree with Ricc and Mr. Lyons: One of the biggest advantages to tumbling your brass is to clean the sizing lubricant from it. This purpose would be defeated if the brass were resized after tumbling.

I do what most of the others have indicated: Poke the little piece of cob out with an icepick or awl, the tap the upside-down case gently on its mouth to make sure the particle empty completely out. I let mine drop onto an ordinary 2-cent paper plate, then toss the plate when done.

rock42: Have you run those "corncob projectiles" over a chronograph yet. They might be effective housefly loads. :

I've always deprimed the cases after tumbling, so I don't have that problem, or that step to take care of.
I use a spray lube, so I don't have any residue to worry about either.

I like to tumble the cases as soon as I get back from the range, and then it may be months before I get around to actually loading those cases again.

Rick.

Same as Ric and Rick- I tumble as soon as I get home- then de-prime- using carbide dies to eliminate the lubing step.

I bought some corn cob media for my tumbler last yr. and got tired of having to clean out the flash holes. Went back to walnut media, problem solved. I was getting brighter cases using the treated walnut media anyway.

I've had walnut stick just as badly as corn cob -- it just depends on the size the particles are ground to.

Bye the way, Rick, what makes you think that lube doesn't leave residue just because of the way in which you apply it to the case?

I use the crushed walnut shell media, and it does the same thing. So I now clean all the brass as soon as I shoot it. The I resize and deprime after it is cleaned. It always pokes out a small piece of walnut shell with the spent primer. No more problems.

I normally use a porquepine quill and a 8 lb. sledge, works for me, but it is a slow process.

yea, Good one Ray.

I use the same method that Don G uses on rifle cases. On straight wall cases i just resize them after cleaning....

Tumbling media is a pain. I switched to automatic dishwashing detergent in my Thumler tumbler and it works great and is cheap.

I would still like to see those chronograph results! I have a lot of problems with house flys in the summer, and they are getting "swatter shy" I am in need of a "long range house fly caliber" How is the grouping. I am looking for something that is sub "minute of gnat's a$$"

sorry guys I can't get the chronograph to pick up the speed of a tiny piece of corn cob. I shot about 30 corn cobs granules over the chronograph and it didn't pick up one of them. but them must be going prett fast cause I can hear them hit stuff about 15 feet away.

I clean up the brass BEFORE running it in a die. Saves wear and tear on the die. Sizing lube is water soluable. I wash it off.

We could argue that decapping the brass before tumbling allows the primer pocket to be cleaned, but I clean that out by hand.

One last approach: Find a different size of media. A little smaller or larger and your sticking problems will vanish.

=============================
I use a spray lube that is rather volatile. It tends to evaporate quickly. I suppose there is a little residue left, but if I can't feel it, I don't worry about it.

Rick.
