Velodog, there is no need to run a 458 Lott at full tilt. albeit i think id run it a bit faster then 2000 fps, id run the cartridge at around 2100-2150 fps.
havin the throat bored deeper isnt a bad idea, but you might as well go a little further and make it a Lott if youve done that much. the 458 Lott will shoot 458 WM cartridges if needed.

Hi Matt,
Totally agree, that's why I wrote; "a bit over" 2000 fps.
This is not to mention the several other rants I've submitted on the .458 Lott, throughout AH, specifically referring to hand loading my .458 Lott to duplicate the original .450 NE's ballistics, to help me deal with the recoil during repeated firings of this cartridge.
Regarding the very slight throating-out of the Winchester version, I presumed AZDAVE was referring to shorter actions/shorter magazine box types, such as surplus Model 98 Mausers, built in .458 Winchester.
I had consulted a Gunsmith about having a for sale / affordable but very decent custom Model 98 in .458 Winchester, converted to .458 Lott, 8 or 10 years ago and concluded that I'd save a pile of money by just having a Lott built on the CZ 550 Magnum action, and so I did.
Evidently, the M98 receiver ring needed to be milled out to fit live .458 Lott cartridges, plus the action screws were too close together to accept a Lott length magazine.
The CZ 550 Magnum is a stoutly made and affordable option for the Lott and I'm very happy with the way mine turned out, especially since I have less than $2000. in it.
While we're on this, my opinion is that the .458 Lott is pretty much the only DG cartridge introduced during my lifetime that I'd refer to as "excellent".
Peaceout,
Velo Dog.
