W.Bartram 4 Bore Pinfire Loading Tool

I show my W.Bartram English 4 bore reloading tool. Large bore tools are hard to find and is shown with a French case and a 16 bore tool for size comparison.

That is one big loading tool! How much does it weigh?

The tool is 5" long or 128mm length of the brass part.
It weighs 11.1oz or 317 grams. Thanks for asking.
