I haven't noticed any dinging (see pic). I do it after because the cases are not sized yet, and they may not need to be trimmed. I have noticed a lot of brass shavings, on once fired 300 Blackout cases, (twice if you count the 5.56 shot) which means either I left shavings in the cases, or the chamfer/debur process wasn't as smooth as I thought.fairchaser":m6c3urbn said:Omega":m6c3urbn said:I deprime with my Lee universal deprime die, then wet tumble, then process the brass if it requires it, trim, chamfer, debur etc. When I first got my Frankfurt Arsenal Rotary Tumbler, FART, I did all my brass, and stored it in boxes until I'm ready to reload them.
Omega, do you trim after tumbling due to the pins dinging the case mouth?
Brass shavings
The cases come out much cleaner than with the vibratory method, this is after cleaning, "clean" cases using the dry method.
The left pile was done with walnut media, the right was SS pins, dawn, and lemishine.(middle cases are opposite). You can't see the primer cup on the right, but it is as clean as the bottom of the case. The primer cup on the right, as you can see, require cleaning as a separate step. I also have to inspect the cases after dry tumbling due to media getting stuck in the primer hole. I have one of those rotary media separators that, once you get the hang of it, speed, number of turns etc, separates all the SS pins out of the cases, even the bottleneck ones.
