Just got back from Amsterdam (Check out the Rijks Museum Pics) and was able to go pick up the C Sharps 1885 High Wall.  The gun appears to be new and unfired!

Some Highlights:

It is Chambered in the 405 Winchester which I will try to develop a black powder load for.  Some of the challenges with loading this rifle using a cast Big Bore bullet is that not a lot of companies sell a 400+ grain bullet for this Barrel.  I have ordered some 300 Gn MBW gas checked bullets to start and Custom ordered a 435 Grain bullet from Accurate Molds measuring .405x.413. 

Mould and the Bullets arrived!  I was able to cast some bullets and they are coming in at 440 Grains (20:1).
