pewter. Muzzleloader gunsmiths some times poured pewter nose caps and inlays for the gun stocks they made. Pewter melts around 600 degrees and can be molded like lead. Pewter nose caps for rifles could be molded with just a piece of card wrapped around the stock and barrel. There is a metal that melts much lower, Woods Metal, melts around 190 degrees. Yep a metal alloy that melts at a temperature less than boiling water. (rather expensive) I attended a seminar at Thaddeus Stevens college in Lancaster and they were pouring pewter bands in turned wooden bowls using just masking tape to hold the melted pewter until it cooled. I have been buying all the junk pewter I can find at a reasonable price to use for this.
