I have a G22 with a LW 9mm barrel. I determined that I needed 4.4gr of Bullseye under a 124gr Montana Gold JHP for the slide/ejector to function correctly. Last night I loaded up a hundred and noticed that my powder charge had drop to 4.2gr. At 4.2gr the slide/ejector does not function correctly. I get brass high and stove piping a high percentage of the time. When I dont the brass goes left instead of right (shooting right handed). Can you help me understand what is happening and do you have any suggestions to help the situation? I would like some powder tolerance and +-.2gr does not seem like a lot. I would take the charge up to 4.6 but I am concerned about too much pressure in the case.
