FInd a Kahles CL with a one inch tube and don't look back grin . That said I own a Z3 4-12x50 which bit the dust on a 7 WBy after a few shots. I have it mounted on a 270 WIn now and it is a superb lowlight scope , very light and it fits in extra low optilocks on a Tikka T3. Swaros warranty service is beyond reproach and has always been that way.
