A shallow trench dug in the ground and filled with dry-ice is a good way to get them out.
Replace the rear guard screw and screw it into the gun, Then back it out 3 turns.
Then you bury the gun in dry ice for about 20 minutes and have gloves on when you take it out.
A few blows with a hardwood stock or large hammer handle on the underside of the barrel and a blow with a hammer and punch against the rear screw will usually pop one right out. Once you have it loose and it wiggles a bit remove the screw and then you can use the barrel and the open bolt as "handles" to rock it back and forth with upward pressure and walk it out.
