Is it correct that 6.5 PRC uses large rifle primers and magnum are not recommended?

I am using the Federal 210M, and using 57gr of powder, I don't see the need for a magnum primer. I haven't chronographed the load in cold temperatures, but one thing I do like, is that I am not seeing any copper fouling, which makes sense given that R-26 contains an agent to reduce copper fouling.
Here is some testing that might interest you, concerning R-26 in colder temperatures.
