I have been trying to find information and drawings on both of these cartridges and there simply isn't very much information on the WEB that came from ORIGINAL government or factory data.

Here is some of what I have found and I hope some of the board readers will add to this information. If you have ANY original drawings or copies of text regarding this subject would you PLEASE post it here.

To begin lets discuss why the round is now referred to as 12.7mm. Please take a look at this drawing I made of the rifling in my M1867 rolling block and comment on the note.


Here is a French drawing I have found of the projectile:


And a drawing of unknown origin of the cartridge. If anyone has an original drawing of the cartridge please post it here.
