You can melt it out as well. Connect a transformer, such as one from a electric train kit or racing car kit or one of the small electric fence transformers used for keeping dogs or other animals in.......connect one wire to each end of the barrel, and tilt the barrel muzzle down..........takes a day or so, but this will melt the lead and drop it out the muzzle.
Used it on my 92 back years ago......works very good.
