Have you tried more powder with with your current powder, ball and patch combination? I would do that before changing anything else. You may be pleasantly surprised. If there is a drop off in accuracy, then I would try changes, but don't do it willy nilly. Change one thing at a time. Maybe start with using 3f powder instead of 2f and work up the best load with that. Then change something else. BTW, I also recommend getting Dutch's system.
