I am venturing into reloading and have a question regarding once fired case length for 300 WSM.
The reloading manuals show the length of this case should be 2.100.
I have checked 2 of my once fired brass & nickel cases and found them to be 2.098 (WIN,Nickel) & 2.099 (FC,Brass), this is before resizing.
I am confused, I thought the cases were stretched when fired. What I am seeing is they either have shrunk or they were much shorter to start with.
Is what I am seeing common, or an I screwed up?
