You can use standard primers, remember to reduce charge slightly if your using MAG primers. I switched to standard primers in the 300WM mainly because I buy in bulk, magnum primers are more expensive so I tried standard primers after using MAG primers exclusively thinking it was needed, ignition was still good. I would imagine that when using certain powders in clold climates it may be a better idea to stick to magnum primers, but I have no basis for this.
