I had the same problem about a year ago. Bullseye asked if it was a live round or an empty case, mine was a live round. Either way you cant take the gun apart because in order to get it apart you have to uncock it by pulling the trigger. If it is an empty case, just lock the bolt back and run a cleaning rod down the muzzel and push it out. May take a little persuading with a few taps from a hammer on the end of the rod, but it should break free. However, if it is a live round, BE CAREFUL WITH IT! I used a cleaning rod to remove a live round the same way. I've also removed one from a friend's gun with a pocket knife while we were in the woods. I put the dull edge of the blade under the rim of the cartridge and pried it out. I know neither of these sound safe, but I didnt know what else to do. I would suggest the cleaning rod first, so you dont accidentally set off the primer. Neither way sounds safe and you should use your own judgement before attempting either one, but I didnt know what else to do. Maybe someone else will have a better idea.
