The bullet ladles I seen in museums are for the most part too large to be a bag ladle. I have seen a few small ones that like the nice example pictured, require some sort of a heat resistant handle be added. Most of the ones I have seen in collections are more like the example Hershel House makes in his blacksmithing video, and are vey small by todays standards. I believe since I live in the far west where supplies could be pretty scarce, they reused their lead as often as possible. I seem to remember seeing a small copper, or brass ladle in either one of the California Missions collection, or at Ft Ross, the Russian settlement on the California coast.
