I've been having a reoccurring issue in one of my PPK/S builds where the barrel apparently is rotating counter clockwise in the barrel hood.
At first I thought that perhaps my instilation of the barrel had not been precise when lining up the cuts on the barrel and barrel hood for the extractor to fit. Everything functions flawlessly until around the 40 round mark, when the weapon starts to get good and warm. I thought that as the metal started to warm and expand, it created a tightening environment which caused the extractor to snag on the barrel itslef.
This past range day however, I know it it's not the case. I reset the barrel absolutely perfectly and around the 40th round the extractor got caught once again on the barrell. The barrel had rotated counter clockwise 1mm or 2 within the barrel hood and was in the path of the extractor.
Does anyone who has done builds know a sure remedy for this. I want to keep the barrel if possible as it fits the West German build specs of the rebuild, is outstandingly accurate, and bluing is almost 100%.
Also possible causes? So far I'm thinking that whoever stripped the frame originally might not have done so with great care and may have stretched the barrell hood. Or perhaps the issue could be with the barrel itself or the barrell pin?
