On that quality rifle Swaro all the way. On my John Rigby in 275 Rigby I put a Swaro Z5I on it in 3-10 44MI am looking to purchase another plains game / North American big game scope for my Highland Stalker in .275. Most likely it will be used between 50 and 250 yards. I have a Leupold VX-3I 3.5-10x40 on my CZ in 30-06 and have had no issues. I am curious if the step up in cost with the vSwarovski Z3 3-10x42 has a commensurate step up in performance. Any real world experience with both?
