I had a Lang on the smaller frame for awhile. I also had a Wilkes two barrel set with a 360#2 and a 470.

The 360 is a nice cartridge but I prefer the 9.3 because of the handiness of the rifle. The Lang was a sweet rifle though. I met a guy in Sydney once who claimed he was shooting 286 grain bullets out of his #2 at 2500fps. I don't know and never saw the rifle but it would have been an interesting piece if it was a smaller frame.
