Hi I have a springfield range officer 1911 I had the barrel tin cores and since I’ve had it back I’ve had some issues with rounds failing to eject. It ranges from stove pipes to the slide catching the spent casing on the top of the barrel on the way back kind of crushing it. It also seems to be random and not affected by changing out my recoil spring ranging from 16 to 12 since I do reload and am currently shooting lighter loads. All my loads do pass plunk tests and it has happened with both 200gn lswc and 185 copper plates fnrp. It almost makes me think it has something to do with the extractor and the barrel coating is just a coincidence but I don’t even know what to look for.
