I had a CZ 550 Safari in .458 lott and it was a bit rough in the action department. It probably would have been fine with some use of a buff up by a good smith. It was adequate in the accuracy department. I however sold it and got a Ruger M77 in the lott chambering. I havent regretted it a bit. It is smooth and fast. I have fired several hundred rounds through it and taken a daggaboy and a big bull hippo with it. As for the lott caliber, sure alot of folks load them down to velocities attainable in .458 winchester magnum case; but what the heck is wrong with the capability of the full power lott too. It would be a good bet for elephants!
