I shoot a Savage 24f in .223/12ga. I tried some Wolf .223 thru it and at first it worked fine. The gun's a single shot break-down. It never really slings the spent cartridge out. After firing between 10 to 20 rounds at a leisurely rate it started really popping them out. A few more rounds and the gun didn't want to open. I forced it open and the extractor ripped the case off. I had to remove the extractor pin and had to use a antenna wire to shove it out. I know that many use Wolf lacquered ammo in their AR's without problems, my question is has anyone had similar problems with other single shots?
