Thread: What is the best case trimmer for consistency?

Note with the little crow - I've found it is better to use the drill and get the rpm up rather than slowly turn by hand. I was getting a tiny lip forming by hand that needed to be chamfered off that just didnt occur if i used the drill.
- it took 3 firings before i got enough variation to bother resetting the bit a little deeper.

I do take off that edge anyway but its much easier if its a clean cut
