Stocking only magnum pistol primers?

I also use winchester primers. Easy to get and no worries about magnum/ standard

I used to do that, too, but what I found in my limited testing is better numbers with CCI standard or magnum primers, specifically, than the WLP's. I don't use a lot of magnum primers, anyway, so I just kept what I had left for when I needed a magnum primer (for something like H110.)

I concur with someone else I remember saying they lost accuracy using magnum primers. Using Unique in both a .357 and .44 magnum I lost nearly an inch of accuracy at 25 yards trying magnum primers. To me going from 1.5" to over 2" was plenty reason to stick with standard primers. Both guns were Dan Wessons. If you want precision I'd definitely try the same load and shoot a few groups with each type primer.
