When you feel confident enough up the load to 60 grains (60 grain spout). So long as you measure by volume and not weight you'll be fine.
I would say don't bother with a conical bullet (correct me if im wrong) because the bullet would tumble and be very inaccurate since you have a smoothbore, so a patched round ball would be more suited.
