Some ball powders are indeed harder to ignite than extruded - or even other ball-type powders. So SOME sources use magnum primers with ALL ball powders, no matter what the other circumstances. That certainly works, but it's like wearing rain gear in all weather conditions.
With cartridges holding less than 50-grains of powder, or for when shooting at temperatures above freezing, a standard primer will usually be quite sufficient even with ball powders. If you suspect poor ignition (inconsistent velocity, poor groups, vertical stringing) then start over at START level with magnum primers.
