Long load the 458 Win mag and it will out run the Lott
Why not ream a WM to the Lott and have the best of both worlds if the mag is long enough? CZ550 Safari's definitely have the mag space.
How is that the best of both worlds? Where is the advantage of doing so?
In a CZ550 with a 3.750" magazine, Lott cartridges fill the magazine more completely and so should feed more consistently.
Lighter, shorter bullets are closer to the rifling which should improve accuracy. My CZ is abysmal with shorter bullets, a 350 TSX and many cast are well clear of WM brass before they begin to contact rifling.
Cast bullets should also be more accurate without traversing a wide, long throat and less chance of bullet "stripping" rifling.
A little more powder room will lower peak pressure.
Can still fire WM ammo in a pinch.
Don't see any point in messing with a standard length action but makes good sense to me if the mag is already long.
