Hey y'all.
New reloader here. i just collected my brass from my first test rounds and noticed that it is .001" shorter than it was when I started. Starline 9mm, brand new to start. It is now .749 down from .750. This is measured after using the lee resize/de-prime die.
So if my brass is going to continue to shrink, do I need to adjust OAL in order to keep pressures consistent? Are there any other adjustments that might need to be made?
What is all this about trimming when the brass actually shrinks? Will it grow at some point?
