Nframe, I think I like it better that the 458 Win Mag is still in tact. As Chris pointed out the gun shoots both bullets and typically could be a 458 win mag/ 458 lott.
I would think of it as a 38 special/357 magnum.
I still don't like that xxxxx'ed out thing.

Realizing that you might not travel across the world it would be nice to hear if anyone had any experience with this sort of thing yet.
