My guess is that you need a hotter, heavier and possibly better crimped cartridge choice. My S&W M28 is sweet with Winchester Supreme 180 gr black box. Stepping down to 158 gr Federal Hydra-Shoks requires my adjusting the sights for POA/POI. I suggest a 6 O'clock hold and one click lateral adjustments in the sights. Experiment until you find the correct combination. The accuracy can be changed by only changing brands of cartridges. I also suggest having the custom GS forcing cone work checked by another GS. 11 degrees is about normal. Ask the second GS to inspect the crown of the bore also. Have them use a range rod on each chamber too.
