I've been using WC 820 (n) for quite a while now in my .44 Magnums (5), and for the most part have used standard large pistol primers. I have not run many loads over my chrony, and accuracy seems to be acceptable. I was reviewing some early loads I have recorded and I noticed a note I had made; "Use Magnum primers". Most of the loads I've used are not barn burners, but running nearer the low side. I haven't used H110/W296 in many years, the only pistol powder I've used with magnum primers, I have enough of both Magnum and standard primers and I got to wondering if loads using magnum primers would be any more consistent with WC 820? (I know I could do the testing/comparison myself, but I just wanna hear from other members )...
