A quick question for the brain trust - I have some pretty significant handloading experience (rifle and handgun), and to my best recollection I have never used a Magnum primer in anything. While going over my primer stocks I notice that I'm under 5K for small and large pistol but I have 7K of small pistol magnum and 4K of large pistol magnum (I think from some long-forgotten trade).
My question is this - keeping in mind that I know I will have to go back to the baseline and develop any load from scratch and not just do a straight swap of magnum for standard primers - how much "real" difference is there between standard and magnum primers in handguns??
many thanks in advance
