Max load (book) is in the 45 grain area. Keep going. As you climb up the charge scale, with any rifle, you watch the groups open up, then tighten. Open up, then tighten. With 4 grains left to go, I am sure your groups will open a little more, then close back up.
The load you have there, assuming that it continues to shoot that way, would be a good for 100/200 yard practice with out beating you up any.
