"I think Dean is correct in corrosion could result in expansion and cause splitting. I also think the wood expanding with humidity or wood constricting due drying out may result in the splitting. If my think is correct, which it might not be, then any heavy metal would resut in the same possibility of cracking the stock. "
Tungsten (which has the highest melting point of all metals at over 6000 Deg F) does not begin to corrode until you reach 700F. Since walnut ignites at around 300F, there is a comfortable safety margin in effect here.
