Brass Trimmings in Case

I have noticed my trimmer is leaving fragments of brass trimming in the case. How vital is this to get it all out before seating?
Since I don't really want to find out through experience, I make sure nothing is inside the case but the powder. This is why I have my 3 way trimmer in a vertical position where the brass is being trimmed facing down so trimming can't go inside.
 
I give mine a good tap on the table upside down. Does the job.

The thing that really worries me is those little ceramic balls when you use dry lube. I stopped using that stuff. Don’t want one of those pieces of ceramic punching through my suppressor.
