I have one magnum rifle and use mag primers in it. I purchased some primed 25-06 on a forum that came with mag primers already in place. So, I worked up a load and used them up. Switched to BR2's and never looked back.
I've never had to reduce or change a powder charge because of the mag primers making the round too hot. They will change how the round groups though. It's just one of the things you can change that will have an effect on your loads.
