Hope someone here can help out. I've been reloading .223 for a couple years now, however I've never trimmed my brass.
I want to start working on tuning my 68 gr load and figure trimming brass will help bring my group sizes down.
So, should the brass be trimmed before or after resizing? I've noted the brass gets longer after sizing. The trim lengths in all my books are 1.750 while the diagrams of the cartridge show a case length of 1.760.
So trim before or after sizing?
Thanks in advance.
