It works great on straight Wall cases with Lyman turbo charge added.  Doesn't work for crap on bottle neck cases. I spent a couple hours shaking it out of .223 cases. I have a dozen or so left it's trapped in the case.  Oh well, I'm getting a swaging die to make .41 bullets out of 9mm cases.  



I was racking my brain what to do and it struck me.  Run put through the grain mill.  

It is a bit dusty. I may make a box with window screen on the bottom and shake off the dust.  

Bird litter is 10% the cost of media at the LGS.  Even with the addition of Lyman Turbo Charge it is still cheaper.

Corn cob I use is used for media blasting.  It is about the same particle size as lizard litter walnut.  Works quite well for me.

ETA:
I can't comment on cost, as a friend who works at a commercial paint contractor got me some to try, and I am still using it.

The pet store was out of Lizzard litter that I usually buy and I thought "What the heck?"  and gave it a shot.  

It does work like charm on straight wall cases.

I will try the ground size in some .30-'06 cases and report back.

Never buy corn cob at a pet store or wally world. Way to big unless you are doing 50 BMG.
You want 14/20 Grist Corn Cob Blasting Media.  McMaster Carr part #32725K63 or Grainger Part #2MVR5

Best Additives IMHO
Iosso Case Polish
Dillon Case Polish
Nu Finish is okay, but the ones above are better IMHO

It is running now with .223 and I checked. The media fals right out.
