Hi all,
I’m going to try and explain to my best ability as to what is happening.
I recently bought an old 1906 Winchester 1892 and have been having issues.
When I cycle a round in first its fine like it goes in and that no problem.
After its fired the round like swells.
I’m not sure whether this is caused by the chamber being too loose around the bullet or the bolt not picking it up on the way back.
It seems as though like its stuck in the chamber rather well.
If you have any idea, please let me know.

Toni,
From your limited description, the chamber is too large. If you can see any appreciable swelling of the fired cartridge case, the chamber size is the problem.

You need to check the chamber to see if it was changed to another caliber and not remarked. Put a round in by hand and then see how much play is between the round and the chamber with your finger. Another thing you can try is measure the fired shell and compare it to a unfired one with a dial calipers.

Definitely happens that folks rechamber these guns and dont mark them to the new chambering, then they get passed down the line to someone who has no idea about whats been done.
You might use a micrometer to determine if the bore is the right size for the cartridge designated or oversized. And if youve already fired around through the gun, and flared cases or case necks are the result, thats a sure sign the chamber has been changed or is damaged in some way. If they are just sticking, you may need to look and see if there are any burrs, deformation, or corrosion in the chamber that would cause the case to stick to the chamber walls after firing.

If you find it has not been rechambered but is “oversized” which from your description is what it sounds like, someone has “polished” the chamber trying to remove corrosion, scratches, burrs etc. In doing so they have removed too much metal from the chamber and that is why you are seeing the bulged casings. Sadly there is no easy fix to your problem. IF you have an Octagon barrel it can be lined and chambered for the original caliber. If it is a round barrel there is not enough wall thickness in the barrel to insert a liner. This place manufactures replacement barrels https://www.winchesterbarrels.com/ And finally there is Ebay or gunbroker where used barrels pop up from time to time.

Another suggestion: Either cast the chamber with Cerrosafe or take to a gunsmith to have them do it, so you know what you’re dealing with.

What caliber is it? If it is 38WCF (38-40) it is pretty normal in both of mine to have the brass in the neck and case area expanded after firing. Most sizing dies for this caliber are designed to leave that case portion expansion and mostly only neck size the case. Is the extractor getting a good grip?
