I'm looking into getting a new hunting rifle that is lighter and shorter than my current rifles (Edge, and Ultra mags) and I am trying to decide on a scope. I am interested in a Zeiss Conquest 4.5-14 and Swarovski Z3 4-12 or possibly a Z5 3.5-18. What are your thoughts between the Zeiss and Swarovski? Also is there any difference between the Z3 and Z5 other than magnification range? This will not be my long range gun and most shots with this gun will likely be well under 300yds. Any info would be appreciated.
