I responded to your earlier thread, but I will add my more recent experience. I finally used up the last of my new brass color winchester primers, and until I hear otherwise they are off my list. In several different guns, WLP, WSP had failures to fire and failures even after a second hit. Since my problems cross guns and calibers I have to attribute it to the winchester primers.
I have since switched to CCI with no problems to date. What primers are others using instead of winchester?
