I have used Remington primers exclusively for over 25 year. I've never had a single problem with them. I don't know how many I've used in total, but in 9MM alone the figure is well over 200,000. Remington 9 1/2 large rifle primers and Remington 7 1/2 small rilfe primers are the only generally avaliable rifle primers that meet MilSpec. (CCI mnakes a MilSpec, but it's special order.)
When I was in the commercial reloading busines in the 1970s, we used Remington exclusively and never has any complaints from our customers that could be traced to the primers.
All of his is not to say that other brands are not good, but with the experience that I've had with Remington, I just stick with them.
Many, many years ago, I did use several thousand RWS German primers and they were suberp.
