Tumble after trimming?

[Kwaynem]

I have been trimming 223/556 brass all day and I’m done for a while but noticed a lot of dirt coming off them is it ok to tumble after trimming?? Also I have a few cases with the head stamp GFL what manufacturer is this?

GFL is Fiocchi.

I've tumbled brass after trimming. I don't think it hurts but there're probably some shithouse engineers that think it'll work-harden the necks or something. lol

After trimming/chamfering is when I put them in tumbler,

It cleans lube & brass bits off.

I usually tumble them after loading, well Vibrate them anyway. Clean media with some 90%isopropyl alcohol. Gets all the lube and stuff off of them.
