ejector/extractor mechanism question

[Chuck Heald]

I'm tuning on my repro and have recut the chambers to nominal on the CSM barrels, because they were very tight. I also cut long cones in it and polished them.

I was also having a problem with the rim of the shells hanging on the top of the breach of the frame. With the gun in the fully open position after ejecting empties, the extractors sit up just high enough that the rims are over the frame. I'd like to trim the end of the extractors about .030-.040" where they contact the ejector strikers on the forend.

My question is:
Does the extractor play any role in cocking the ejectors as the gun is closed?

Hi Chuck, Are you sure the gun is staying fully open after the empty's are ejected. It seems to me that if there is enough clearance for the empties to eject there should be enough clearance to load new shells without hitting the top of the receiver. I suspect the barrels are closing a very small amount that is not noticeable. Cheers, Tom

Tom,
Yes, the gun stays open fully. It is not until the gun is started to close that the shell rim makes contact with the frame.

After recutting the chambers, the issue has all but been eliminated, because as the gun is slightly closed, apparently the ejectors start to cock and the ejector strikers draw away from the extractors and (with the barrels pointed downward) the shell's weight lets them fall forward into the chamber further, thus clearing the top of the frame. But, laying the gun sideways to observe what's going on, you can clearly see that the rim doesn't clear the frame as it is closed.
