Case Tumbling

Anyone else have problems with case tumbling media sticking to the insides of the case?  I use the commercial ground up nutshell stuff. It does a great job, but the latest stuff I've got seems sticky.  When I take the cases out of the tumbler especially bottleneck cases of fairly small caliber like 22-250 it takes me a full minute per case to get the stuff out of,the case.  Ive resorted to tapping the inverted case with a soft copper rod till the flow of media pretty well stops, then using a drill bit that nicely fits the case I "drill" (by hand of course) any remaining media stuck to the inside of,the case, assuming that I got,all the stuff that might be stuck to the sidewall of the case and inaccessible to the drill.   I completely gave up tumbling the cases AFTER deprimimg or the primer cup would be stuck full of,themstuff and require careful scratching around to get it out.  Then to be sure, another trip thru the depriving die!

Flitz makes the situation worse, IMO.  Even straight walled cases like 45-70 or 50-70 aren't immune, some requiring removal of,a plug of sticky media.  Straight walled cases  empty better than the bottleneck cases but still not,very well.

Any bright ideas from the handloaders?  I just wasted 2 hours removing the tumbling media from only about 100 .22-250 cases! Time better spent a million other ways.  More importantly, while powder charging two cases the powder completely filled the case and overflowed  and on further inspection I found that in spite of my work, there was STILL stuff in the cases, hanging tenaciously to the sidewall, causing the overflow!  This could theoretically at least, create oddball or even dangerous pressures, or a dangerous hang fire if some of this material was plugging the flash hole, despite running the depriving pin through twice!

Wonder if some other media might be better? Suggestions....?

Go stainless steel pins in a tumbler and you will have cleaner cases and all around better results. 

The first 100years are the hardest.

Thanks racksntails.   What are stainless steel pins?  Ive never heard of them.  I knew there were other options rather than corncob or walnut shells, but stainless pins?   Ill look for them!  Thanks!

It kinda requires a whole new set up. It uses water in a tub that spins on a tumbler and has the pins in it to. It cleans like no other plus it will do the primer pocket holes too. I've been using it for years with the same five pounds of pins I started with. Done thousands of .233 and 9mm. I use the Frankford arsenal set up. But there are many out there to chose from. I have friends that even use a rock tumbler that is made for polishing rocks.

I have the same issues with crushed walnut shells, I generally don't have much trouble with the media getting stuck inside of the brass, normally a tap or two  with my finger and it comes pouring out.  I do have to use a dental pick to pop media from primer holes though, it is a bit of a pain.

I thought about changing my setup but it wouldn't pay, I don't load enough to justify it.

Don't practice until you get it right, practice until you can't get it wrong.

I dump the clean brass thru a pastic sieve. then mount the sieve on the tumbler, to the screw that olds the lid on, and turn it on. this will get 90% of the cartridges empty of the media. As I take the brass off while the tumbler is still running, I touch the brass to the screw that holds the lid on if there is any media left it comes out then. Of course this will only work on the old traditions bowl style tumblers.

Thanks Corn.  Ill try your trick instead of my tapping, and tapping, and tapping routine.
