I know Kroil is an outstanding penetrate.
The top issue here is what could remove value? Its really a two level aspect, one is mechanical (screws/cone removal) and the other is finish condition. A restorer would have capability in both though I am speculating its a two specialty split.
I am strongly in agreement with at least a professional assessment (Murphy's as I recall would help or direct).
Any mix other than a specified release agent aka Kroil, leave me concerned. Kroil and others are a known, mixing two chemicals is an unknown both for reaction to each other and possible attack of the gun finish.
Step cautiously, very cautiously. I remember at least one incident in recent years of cannon ball going off, aka Civil War era. Not powder should not survive that long but......................
Ear and eye protection and a face shield, gloves.
Getting the lead out: Giving that a bit more thought, a multi step process would be what I would consider.
Make sure the cones are open. Then drip oil down the cones. It might take a bit, a cone cleaning tool to agitate it down might be needed.
You want to make sure you create no sparks. As other have commented, its really a chambered round (6 in this case) not an open round.
The idea would be to get thread into the ball and then a wood piece over the top drilled out for oversize and a threaded fastener screwed into the ball using washers being added as it lifts out.
Not an area I know of as to lead seizing to a chamber side or not and it comes out easily. Clearly if the cones can be pulled and powder if any inserted driving it out is easy. You have to be sure the punch is vertical so you don't hit the side of the chamber (damage there would reduce value I would think)
