Trimming brass is the worst
You can trim 10-15 cases per minute on any power trimmer provided it has a carbide head. I was basically doing that pace on my drill press with hardly any variation in length. Not familiar Giraud but does it chamfer and deburr also? If not then add the time for that.
Now a note for those who trim gauging off case shoulders. This is fine but I discovered one interesting anomaly. In the way of trimming a couple thousand 223 cases, I would set aside cases that I inserted into FA trimmer that never touched cutter. Went back and measured and they were like 1.761”, and this was after I sized em all. Obviously I didn’t run em completely up into die OR the mysterious “spring back” occurred. I ran em back through trimmer AFTER resizing again, and all was good. However I am keeping those few separate to check measurement in a few days.
So for everyone gauging and trimming from head to neck, just hope your necks are in the right spot!
