I wish that I could say it's as simple as selecting a propellant and a projectile and finding something that shoots well. When I'm working up loads, I generally load 10 rounds each at .2 grain increments, starting on the low end of what your reloading manual indicates. Run them through your rifle, each set of ten on a fresh target. See which one groups best. I'm not familiar with that particular rifle to know its accuracy potential.
