Case polishing

What Media works the best, Walnut shell or corn cob? At one time I was told about something from a pet store, what would that be?

Without commenting on what works best, what you’re referring to is likely Lizard Bedding, which I believe to be finely ground walnut shells.
Once upon a time, I went shopping for some. The stuff I found was too course, in my estimation, so I passed on it, and continued to use corn cob treated with polish.

FWIW;
Now,
With dirty rifle, and pistol brass, I decap , and use SS pins in a tumbler.
My rifle brass that never hits the ground gets a wipe down outside, and a gentle brushing inside.

Ditto. I wet tumble everything. Water, car wash detergent, a scoop of Lemishine, and stainless steel pins. Brass comes out looking like new, and you never have to replace your tumbling media. The only drawback is the drying time.

Per the “experts” walnut is better at getting heavy contamination off, and corn cob gives a better shine.

I personally haven’t seen that big of difference.

As to SS pins, I’ve used it some. The one comment I will make is that while the results are pretty, decapping is necessary and when dealing with several thousand cases (USPSA/3gun) at a time it is a extra step that along with drying makes it way too time consuming.

I use corncob because you can buy it by the sack (as blasting media) then move on.

For some rifle use I will still use the SS pins, but it’s overkill with handgun ammo.

If you don't need pretty, walnut is OK. Clean enough for range ammo in older guns but I would use something better for competition work.
