tumbler question

For pistol brass I tumble before I reload as I use carbide dies and they don't require lube. For rifle ( except 223 ) tumble, then resize, then tumble again to take off the sizing lube. I use to not re-tumble but sometimes there it still too much lube inside the neck of the case and it would get stuffed with powder and dump all over the place

I only reload rifle, and no carbide dies so I tumble to clean, deprime, and then tumble to remove the lube left on the brass.
If you tumble after depriming, you have to check the flash holes for tumbling media. A quick poke with a dental pick works fine and gives you an extra opportunity to check over your brass for problems.
 
I tumble before I do anything to the brass, then I run them through my progressives, and tumble the loaded cartridges for about 15 minutes to remove the lube.
 
what i do is resize and deprime and then tumble. as was said already, it gives one an extra time to inspect the cases. and in my case, the inspection has been good because some brass was starting to split. just my 0.02
 
Tumble first - then all the other case prep operations after.

Tumbling deprimed cases (with corn and walnut) results in media getting stuck in the flash hole.

If this happens, I run them through the sizer if they're not already sized. Otherwise, I use a universal decapping die to pop out the kernel from the hole - the decapping pin clears the hole.

Good luck - SD

Just a word of caution about tumbling after reloading, some people do this and others don't. My risk tolerance is very low so I've never done it. There is a risk of causing the powder to breakup which can significantly change the burn rate. Can you say pipe bomb!

I did a pile of reading on this before coming to the conclusion that I could do this safely.

Everyone should come to their own conclusion, mine was that 15 minutes in the tumbler is less problem then thousands of miles vibrating under the seat of my truck. (I did base it on more then this though)
 
When I reload 9mm I tumble first then de-prime/resize. I don't tumble again, just the once at the beginning. I don't have the need to re tumble as I don't lube my 9mm cases.
 
I tumble handgun cases first but rifle cases get tumbled after resizing.
That way I dont have to worry about any lube left on cases.
