Tumbling AFTER resizing??

[ETD1010]

Okay. so I've only had a tumbler for a little while now, but I was wondering... I tumble a couple of hours BEFORE I de-prime and resize, but if I tumble AFTER as well, do I have to resize again?? I would think that it would be okay NOT to, but I'm not sure. . . That way I can trim them and de-burr with a second tumbling.. Thanks!

The short answer is no, but if you tumble after you decap and resize you do need to visually verify that you have no tumbling media stuck in the flash hole. Resizing it after tumbling would run the decap pin through the hole to make sure it was clean, but if it was a rifle round you would need to lube it first thus neccesitating the need to tumble them again, a viscious cycle indeed! I always tumble, lube, decap, resize, tumble again, trim them for length, inspect the flash holes, prime, charge, and seat bullets, done. This is the basic run down for your everyday blasting ammo.

You only need to resize once per loading.

(for rifle
Tumble, lube, resize/deprime, trim, deburr, prime, load.

Sometimes I'll tumble again after trimming/deburring to get the lube off and brass shavings out, but then you'll have to look into the primer pockets for stuck media prior to repriming.

I tumble before sizing to remove any dirt and generally clean up the brass.
Then I lube, size and trim.
This leaves the cases lubed afterwards.
I tumble again to remove the lube.

When loading, I put a decapping die in station one of the press.
This ensures that every case gets the flash hole cleared out before being primed, charged and a bullet seated.

I tumble straight walled brass twice - I like my brass shiny. Bottleneck cartridges get a second tumbling as a must have - to get rid of the lube. I visually inspect the flashhole for stuck media and store them base up in trays so anything stuck inside will work its way down and out.

Thanks guys. I guess I just have to develop my own "work flow" now with a tumbler.. before I pretty much cleaned my cases by hand since I didn't reload mass quantities (like more than 20-40 at at time). Thanks again!

if my rifle brass is not too dirty, i trim, deprime, resize the neck, tumble, debur, chamfer, clean primer pocket, and load up.

for pistol, i tumble first, resize, then load up on the dillon 550.
