Safe thing to do if switching any component, is to back your charge off by 5% or so and work back up.

I'm not familiar with that particular load, but the simple answer is - yes, back off perhaps 10% or more and work up your load again if you make any change in components, and particularly if you change from a standard to magnum primer.

Ditto 10% when a component is changed, then work up as wanted.
