Obviously, you are supposed to use lead to seal a lead caulked drain joint but I am hesitant to use lead due to concerns with lead poisoning. Is there an alternative to using lead? The guy at the plumbing store recomended sealing the joint with epoxy. Is this a good solid alternative?

I am willing to cast with metal but don't know if the non metal alloys suggested so far rust or not. Anyone with a bit more knowledge of these alloys?

Will silicone sealant remain in place or will it be pushed out once the oakum gets wet and expands?

I would be reluctant to use epoxy to seal this joint. The great benifit of the lead caulked joint when done properly is that it is very sturdy, but if it ever needs to be taken apart for mainanence, or to add another branch to the line, you can heat the joint until the lead melts, then pry the oakum out and undo the joint. If you feel that you must use an alternative to lead, there are casting metals that have similar melting points that are non-toxic, or less toxic than lead. If you were to use one of these alloys the joint would likely be just as strong, without the absolute permanency of an epoxied joint.
Here are some of the casting metals that you might take a look at (the last one has the closest melting point to lead, while being lead free):

UPGRADE TO PLASTIC! Cast iron plumbing is obsolete, The inside walls are rough, joints deteriorate and it's hard to work on.
Plastic is trouble free and lasts forever, is cheap and easy to work with. No special tools required. Cut the cast pipe and attach plastic with a rubber coupling.

i might pass hubless, and additionally you will could do this for the restore of the hollow on the backside in case you intend to cut back out the previous pipe. you'll be able to could interrupt out lots of the concrete around the pipe to supply you adequate space to attach the coupling. try this intently so which you do no longer positioned yet another hollow in the pipe. that's advisable to think of roughly setting up some extra help pipes between the floor and the better coupling hub. the two rubber joints you will deploy heavily isn't as good because of the fact the previous hubbed pipe replaced into.

cut the cast iron section out replace with PVC pipe all you need is some glue cleaner and a saw just use a no hub coupling where you convert
