Hey guys, has anyone ever had this happen?
About a month ago, I was working up 800-X and Hornady 155gr XTPs. I loaded a work-up up to 12.2gr (CCI 300, COAL 1.260, STOCK G29) of 800-X, and I had to stop at 12.0gr. I wasn't really seeing too bad of signs of over-pressure. I had ONE tiny Glocksmile out of ten rounds, but I had maybe 4-5 cases get caught and crushed in the slide as it was returning to battery. I assumed it was due to excessive slide speed, and the slide was coming back and catching the brass before it could eject.
Since then, I put a 23lb Wolff recoil spring in my gun, and wanted to try again. This time I was working up with 155gr Silvertips. I shot 5 of the 12.0 load, and one of them did the same thing. No Glocksmiles, and I saw less case expansion than last time, I'm guessing due to the case being supported by the barrel for a little bit longer. I'm starting to think maybe the cases are getting caught in the chamber due to expansion, or they are getting stuck in the extractor. Also, the earlier tests were with Remington nickel cases, this was a new Starline brass case.
Another weird thing: before, all the cases were crushed and stuck in the slide (between the breech face and top front part of ejection port in the slide, the part that slides over the barrel hood) causing a jam. The one that happened today apparently managed to eject. I didn't even find out it had happened until I was picking up the brass. HOW IN THE HELL could this piece get caught and crushed like that and STILL manage to eject?! Weird.
I thought the Wolff spring would have fixed it. Here are some pics, anyone seen this?
