With cases fired in my own gun, so far I have been neck sizing, and leaving the fire formed case untouched.
I've been doing this in order to preserve cases as per what many advised on here.
I must confess that the details of the full case sizing detailed by Crusty Dreary' are a little lost on me (I'll be sending you a PM for that document if you don't mind!!).
This is more to do with my lack of knowledge of technical terms rather than the instructions, I should point out.
I will say, however, that after firing, sizing and cleaning it, I have barely had to trim any of them. Perhaps that is a good sign!!
You cannot wake someone who is pretending to sleep. Stop pretending. Wake up.
Doubt: ...it's the only thing I'm sure of...
