I have recently assembled an AR in .300 BLK and will be loading up rounds as soon as I get dies and other components. However, I have a question about which primers to use. In my Hornady manual they use Winchester Small Rifle primers. I assume, then, using standard small rifle primers is fine. Or, should I use CCI #41 primers exclusively? Anybody have slam fire problems with handloaded .300 BLK ammunition using standard small rifle primers? FYI, I have a standard A2 buffer spring in my AR and Hornady used a Smith & Wesson AR-15 for testing their loads (not a "universal receiver").
