Sounds like a nice one Blackhorse. I have an Alex Henry 12 Bore full rifle made in 1879 that weighs over 13 lbs. The factory records show it was made for steel cored bullets or explosive shell bullets. The case length is 2 5/8" and the charge is listed as 6 3/4 drams. It is a brass case double rifle and the Alex Henry mold with it casts a .750 bullet weighing 1009 grains. It is #1 of a pair. I have a book written by the owner of the rifle describing a very long safari tracing the Livingston expedition in 1879. Much talk of elephant , buffalo and hippo shooting. Good results with the steel cored bullets, explosive shells not effective. Dr. Findlow had a great article shooting the 12 Bore rifle DGJ Autumn 2002.
