I am working on a 6.5 carcano.Developing load but having a problem.loaded bullets and unloaded brass cycle fine but once I fire a round I can't get case to eject I have to tap spent case out with an old cleaning rod and alot of force.I was told by a friend who is into building his own rifles that the chamber is in need of polishing. Upon looking at the chamber I now know why the cases are sticking.The chamber is somewhat rough not smooth like it should be.My buddy said that I should get some fine steel wool and make an arbor for a cordless drill and polish the chamber with fine steel wool to clen up chamber?Are there any other options?
