Magnum Charges are all fine and good if the rifle likes magnum loads and produces accuracy,and it is safe to shoot them. I think all too often people get an idea that more is better. If your going to shoot the powerbelts, I personally would avoid the magnum charges as the powerbelt can react sometimes with less efficient penetration and expansion.

The use of magnum loads is not always necessary for most of the shots we take. Granted they have their advantage, but if you are getting good accuracy with your current loads, you should at least keep them in mind for if in the event the magnum loads do not work out for you.

You will probably find that magnum loads will really not be an advantage for you. You will also have to understand that you will burn more powder, suffer stronger recoils, and you might not like the way the rifle reacts. But then everyone needs to try them once.. Just make sure that the rifle is safe to shoot magnum loads and do not exceed the manufacturers recommended loads.
