Bill, I have used a lot of pewter here are some suggestions. The bullet ladle that you need is made by RCBS there are others but thy are not as good.
I get my pewter from a caster that cast those figurines that are all over.
When you make your paper mold use a brown paper sack or a file folder a wore out J weight belt also works good. When you heat it, I heat it in the ladle with a propane torch heat it till it starts to frost, you need it hot enough to stay liquid till the mold is full, start pouring and don't stop till it is full. If you need to clean the melt up use a sliver of bees wax.The tape I have used has been the Scotch type however there is a new duct tape that is the cats pajamas for this. The tape is green and works great just be sure that the melted pewter wont get to it or you will lose it. If you screw up you may be able to fix it be making a welding rod out of pewter just pour it into a angle iron then cold forge it fine enough to use then use a SMALL torch with a fine flame to weld up the defect, ask me how I know this. Any problems send me a email. Gib
