Pure lead will cast the smallest, but I don't think it'll get you to .687".

Depending on the composition of the boat keel, you should be able to cast a little smaller with pure. Also, I believe that casting hotter will allow the cast to end up smaller due to shrinkage( I may have that backward). I would try pure amd play around with temp, casting very hot and just above slush to see what works.
Also, some have sprayed the mold cavities with a mold release such as Frankford arsenal drop out or whatever it is called. The mold release or a spray graphite will added a layer to the cavities and cast a smaller ball.
Just tell him to use a thicker patch......if he would bring a micrometer to a fabric shop or a thrift store he could find a lifetime supply.
