Since I returned to reloading several years ago, this time for pistols only, I've used Winchester, CCI, and Federal primers, both Small and Large Pistol. They've all performed perfectly in my Glocks, with nary a failure, and perhaps because they're more easily available locally (at Bruno's), I've been using only Winchester SPs in my 357SIG loads the last couple years. I read and posted in a recent primer-quality thread where several people complained of poor functioning of Winchesters; my comment was that I've used many thousands of WSPs with NO negative results. So finally a question--from perspectives of reliability and performance, have you experienced ANY differences between Winchester and CCI SP primers? I ask because CCIs from Powder Valley are significantly less expensive than Winchesters from Bruno's.
