corn cob

After reading that I can obtain corn cob media at Petsmart in bulk I went to get some. Sure it is cheaper there but the size of the grit seemed enormous. Will this size media work well? Some of the granuals seemed to be the size of a small primer pocket. They also seemed to have sharp edges. I was wondering if this is ok to use. I was concerned about scratched cases. I would rather spend a little more on media and not worry about scratching on my cases
 
Grainger 20/40 corncob media is the best. I deprime (decap) the cases before cleaning, and this product does not contaminate the primer pockets. Order it on-line, and you will be very pleased with the results. (I add some NuFinish to the corncob.) Best wishes.
 
I used the larger grained stuff on finished rifle rounds to remove the case lube. I wouldn't use it on rounds that it could get stuck inside of.
 
Larger corncob media can and will get stuck in cases, especially bottleneck ones. I tried some cheap stuff I found in a pet store and paid dearly for it. I had to manually remove the media from 200 or so .270 and .223 cases with a piece of stiff wire. It took hours.

Small corncob media works perfectly, though.

If it's bigger than #6 shot, I'd pass.

mps has it right. 20/40 is what you want. I live near a Graingers so there is no shipping. Just shop around for best price.
 
The size of the grit makes no difference. Any media can get stuck in places you don't want it. Still no point paying the money demanded for the same thing with the word 'gun' on the label.
 
I got the 14/20 which occasionally gets stuck in a flash hole. Easily poked out. I assume the 20/40 would not have that problem. The large size(bird cage litter) works it's way into bottleneck brass like the 223 and jams in real good.
 
I have always been able to clear my cases with just a shake or rap. Yes I usually have to poke a granule from the flash hole. The other day I got the not so bright idea to toss in my sizing dies. I found them wedged tight with corn cob and the threads were all gritty. I had to blow them out and brush off the threads, then blast the dies with Gun Scrubber, followed by Barricade after they dried. I won't make that mistake again.
 
I tried that "pet bedding" crap ONCE and threw the stuff away. Large chunks jammed up in primer pockets and clogged case necks causing lots of handwork to remove.
Spend a couple more bucks and get the real thing and go on with your life.
 
The pet bedding stuff is cheap but it's not the best size for case cleaning, make sure it doesn't clog in cases and primer pockets and be sure flash holes are clear. I tumble fired primed brass to keep the pockets clear, but at times the stuff would get stuck inside a case.
I went back to treated walnut made for case tumblers and reloading, not as many problems with it and I like the way it shines up the cases.

Math teacher, what were you thinking, putting your die in a corn tumbler. I would expect that from a math teacher but not a reloader. Sorry, just couldn't resist.
