JB, I had to laugh at your question. I don't have anything against magnum primers but recently used up all my Winchester WLRs (old stock) and bought CCI 200s. I have a small supply of WLRMs and a couple hundred old CCI 250s. When they are gone, I'd like to keep it simple and just use CCI 200s. Right now, I'm using the WLRMs with the last of my H414. When it is gone, I intend to stick to powders that CCI 200s will light properly, Varget, H4350, IMR 4451, TAC. BTW it was on your advice that I switched to CCI 100s! I was afraid of Winchesters after all the piercing issues with some of the newer ones anyway. I had no problems with my 25 or so year old stash.
