I loaded some target ammunition for my 223 Remington bolt gun using RP nickel brass and CCI BR4 primers. After shooting them, I noticed that most of them stuck in the chamber and had to be tapped out with a cleaning rod. I found no signs of high pressure that might cause this, and the extractor was in good shape. After polishing the chamber, the same loads still refused to be removed by the bolt. Further testing found that RP nickel brass, using either Rem 7-1/2 or Fed 205M primers, did not stick in the chamber. Also unplated brass (brass) did not stick with CCI BR4 primers. What I learned was that this rifle did not like RP nickel brass loaded with CCI BR4 primers, but it did like any other combination. Have you found anything like this?
