CZ-USA produce the 404 Jeff, 500 Jeff & 505 Gibbs (not sure if there is a 450 Rigby version) - they fit local barrels and stocks and do bedding. CZ only produce the more run of the mill 375H&H mag, 416 Rigby and 458WM. I think also CZ-USA do the conversion to 458Lott on the standard 458WM - some are double stamped with both 458WM and 458Lott.

We were wondering when you were going to get bored with the 458Lott
