Thanks for the welcome

I was quite amazed at the performance of the little Max on the deer I shot. He simply folded up right where he stood. The wood is Myrtlewood.
Here is a pic of the .50-90 project, with the wood being preliminary fitted. Note the pipe and the dummy bullet. I wasn't sure the big case would "turn the corner" in the Martini action, so I threaded a piece of pipe for it, made a wood insert "chamber", and made a dummy round to check.
