After having some hangfires on a load, I decided the following.
Use magnum primmers for:
-Hard to ignite powder, usually slow/ball powders.
-When recipies call for 60+ gr.
-When loading below about 85% case capacity.
-Or if getting close to multiple of these conditions.
It is no fun to have a large cartridge in the chamber and hear a click. Especially if it could be followed by a delayed kaboom.
