Mixing Cob and Walnut

2 hours on a TIMER (they actually make them)

Coarse corn works best. Walnut only works well when it is coarse and for really filthy brass. Like the Tough Nut stuff.
Fine walnut doesn't do very much.
Most people do not change the media enough they think it last for years? That's when it makes a lot of dust, but this has been winnowed enough:)
 
Hi...
I have tried walnut, corncob and washing brass in lemishine, Dawn and hot water.
Washing the brass and drying takes a lot of hands on effort and time, corncob in my opinion doesn't work as well as walnut.

I run my tumblers for about 3-4 hours...generally separate the brass by caliber before tumbling.
I clean rifle primer pockets after depriming and resizing. Handgun brass ...sometimes I clean the primer pockets after depriming and resizing, sometimes I don't. Don't think it makes any difference to be honest. I can't remember the last time I cleaned primer pockets on .357Mag, .45ACP, 9mm, 10mm or .40S&W. They all get reloaded on my Hornady LnL progressive presses. I never deprime before tumbling.
All of my other revolver reloading is done on my RockChucker and O clean the primer pockets about every two or three times they are reloaded. Usually do somewhere between 250-500 in each caliber from .38Spl, .41Mag, .44Mag, .44Spl, .45Colt and .45AutoRim. I also keep a batch of 500 cases in .357Mag for heavy loads with jacketed bullets that get the primer pockets cleaned every few loadings.
 
generally separate the brass by caliber before tumbling.

I don't separate by caliber IF the mixed brass are:
1) easy to differentiate
2) one won't get stuck in the other's mouth
so, 38 and 9mm - yep mix them together
357 and 38 - nope too much time sorting afterwards
45 and 9mm - nope, made that mistake ONCE
 
I like corncob I bought a 25 lb bag a few years ago. Walnut was too coarse and does not shine as well. I run it for 3 hours with a cap of mineral spirits. Change the corncob after 10 or 12 batches of brass depending on how dirty it gets.
