Seating deeper raises chamber pressure Be extremely careful when doing this
Exactly! Last yr I tried some WSF for reloading 9mm 124 & 147 RN and TC and after looking all the data I had and could find
only showed C.O.A.L. of 1.169" which does not work in my wife's Canik or my p320X carry. So I had to start below lowest powder charge to (in my mind) prevent a possible over pressure issue..
