I own the tract turion and meopta meorpo in 3-9x40 and the leupold vx3I in 3.5 -10x40 all sem to be good scopes. I like the glass best on the tract the eye box is a little lacking but eye relief is fine. The meopta and leupold are very similar in glass to my eyes. The leupold has the best eye relief and eye box hands down. All three have tracked correctly so far and hold zero fine. I have a custom dial on the turion on a 1" model 70 in 270 wsm. So far I have dialed to 3 and 5 hundred yards and returned to zero right where i started. Hopefully this holds up. Ps the turret is capped to which I love. You won't be dissapointed with any of them.
