Stick the cylinder in the freezer. Leave it overnight or if you are at home all weekend. Then use a drill press to drill a large enough hole in the lead bullet to allow access to the powder. Remember that in a worst case that heat may be enough to ignite the powder so the most cold that you can get it the best. Also given that lead and steel expand and contract differently in cold (and heat) that may very slightly break the seal. The other thing is that mercury will dissolve lead. But both are poisons. Mercury if handled without care is not your friend regardless that as a kid fifty plus years ago they gave you beads of it to roll in the palm of your hand in school science lessons.
