LAST EDITED ON Nov-13-12 AT 09:35AM (MST)[p]Leupold VX-3 4.5-14X40
or
Zeiss conquest 4.5-14X44
I would go with the one that has the better reticle for your load or your prefernce (looks better to you)
Zeiss has a calculator to see how closely their reticle matches your load. You have to do the math yourself for the leupold, but it can be done and you will end up with 500-600 yard gun with aiming spots in 100 yard increments pretty easily.
Both have great glass and are well built. The zeiss is a little better optically. Neither is a big package either.
