My preference is Federal primers because they are the softest and ignite with lighter firing pin strikes than anything else I know of. In my race guns i'm running light main springs and Federal is the only brand I have not yet experienced at least 1 light strike. Supposedly CCI is the hardest but I have had less light strikes with CCI than Winchester and Remington put together. So CCI would be my second choice based on reliability of ignition. Some say magnum primers are a little harder but in my experience none of my guns have ever had a problem with Federal Magnum primers. I have only tried Federals brand magnum primers but I run them in a lot of my light 9mm loads and occasional in my 38 Super when I cant find standard primers.
