458 Lott
More rifle than one will EVER need, PERIOD.
I have to disagree with the previous poster when comparing the "Safari" Win 70 to the CZ550 Safari Magnum.
I happen to own one of each; The CZ is in 458 Lott and the Win is in 375 H&H.
While the Winchester is moderately nicer in finish, what you get over the CZ is VASTLY overpriced in my opinion. The Winchester offers one virtually ZERO in added utility. If you are purchasing a "working" safari arm to be used, go with the CZ, If you are purchasing for a "show off" piece that you are afraid to take into the field for fear of beating up the finish, and have the extra $$$ for the "warm fuzzy" of buying a US made product, go with the Win.
Don't take me wrong, I REALLY like my Winchester Safari, however the cost/benefit analysis steers me to the CZ.
