I just picked up a p3at (apparently from around 2005, so it was new old-stock), did a light F&B, cycled 100 times, and took it to the range today. I really like the gun and trigger. I had one failure to chamber in the first 60 rounds of PMC FMJ, and a quick tap&rack solved that problem. Then I tried to run some Black Hills HP. Total disaster. For some reason, fired brass would hang on the ejector every couple of rounds. And after clearing, the nose of the next round might be damaged. So back to FMJ, and no problems. Back to HP, problems. I guess I need to try some other HP make and see if it is just a bad batch of brass or if I have some work to do. Any troubleshooting suggestions? What is the best feeding HP round?
