I just bought a 1950 38/44 outdoorsman. The gun looks good and is tight in every way. The problem is I can’t get it to group well at all. I’m shooting 158gr SWC with 3.5 to 4.2 grains of bullseye. I’ve also tried other jacketed bullets and different powders. At 25 yards the groups are 4in sometimes and that’s from a bench rest. Any help or suggestions would be appreciated.
