I'm a big fan of Whitworth/Interarm Rifles and have owned a MK X and presently own a Safari Grade Whitworth in 375HH. I have also owned a CZ550 in 375HH and a Safari Grade Winchester in 375HH. Of all of them I preferred the Whitworth/Interarms, I like the old school look and feel and they are very accurate. CZs are great rifles and hold one more round but feel kind of bulky as does the Winchester
