My 686 (see bragging board Photo) has 4 inch also - shoots 180 hard cast really well. I never got jacketed to shoot that well especially 158 grainers. I sold my razor and got a Matchdot II - just fits me better. Great groups from yours. Care to share some load data? I plan to take a WT with mine this year.
