I have used nothing but CCI primers for many years strictly because of their availability. But I recently found and bought a bunch of Remington small and large pistol primers for the same reason as the previous poster mentioned. I used Remington 209s exclusively in my 12-gauge trap loads for 20 years and out of over 10,000 used per year, had one dud. Given that, I have no concerns about their pistol primers.
I also recently found Federal Gold Metal Match primers in pistol and rifle types including magnum rifle so I bought some of them, too. It will be a while before I start using any of the new ones as I still have several thousand of each CCI primer to go through first.
I had some bad experiences with Winchester reloading components - brass, in each case - several years ago and the experience with their customer service was even worse so I swore off anything bearing their name. I do use AutoComp powder but since that really is a Hodgdon product under the WW name, I know the service behind the product will be good.
