Re: Case trimming?
I'm with Bill, I only trim when it gets close to max length (less than ~.005 from max). I've had cases that were full length sized come back shorter after firing then before - I imagine the brass stretched to fill the chamber and some of the brass came from the neck area so definitely no point trimming every time if it doesn't need it. I've also found if I meausured before and after full length sizing that the expander ball caused some stretch. Neck sizing with a collet die does not seem to add any stretch so I think it saves some trimming time. Still, can't wait until I can afford a Giraud trimmer, that thing looks sweet!!
