Case trimmer

Another +1 for the giraud. I always say that the best money I've ever spent was on a magneto speed chronograph and my beloved Giraud case trimmer. Next on the list is the giraud annealer!
 
As mentoned the RCBS has a three way trimmer. They work great. Draw back, 2 to 3 cases a minute. I'm saving for a Giraud.

Practice more.

I am able to do at least 4-5 per and I have the old collet style case holder. The Carbide cutter makes it fast as you don't have to crank away for 10 seconds per. Two to three turns of he crank will trim most every case I have.

FWIW, I used to be totally anal about case trimming. Then I measured my chamber length and found I was trimming cases that would take 5-6 firings to even get close to the second shoulder. Now I just trim when I anneal. Deep cleaning in SS pin media, Anneal, Neck Size/shoulder bump, Trim. Rest of the time I just neck size/shoulder bump.
