this twice now the 9mm brass has hit my wife in the forehead out of a 100 rounds. Gun was previously clean during each of the 50 round sessions. I'm using 6.5gr of AA#7 with 124gr xtreme copper plated RN at 1.16 COL.
Would lowering the COL 1.13 help? Or would it be better to add another grain of powder?
