Im not sure how to answer this...
I've got a Leupold Vx6 2-12. It's fantastic. My favorite features are the full 6 times power magnification. I get the broad field of view of 2x, but can also dial into a more precise 12x. I'm also a huge fan of the illuminated dot. However, its a big and heavy scope. I use this both as a big game rig, but its also my target/varmint rifle.
I've also got a Leupold Vx3 3.5-10x. While they are available with CDS, mine is a non-cds version and I do not feel its any disadvantage. I sight for a 200 yard zero. At any range from muzzle to 250, I can simply place the cross hairs on the target (deer, moose) and squeeze off a round. At most the point of impact is 2" high at 100, to roughly 4 inches or so low at 250 or so. If its a 300 yard target, aim 8 inches high, meaning aim for the spine on a deer. The bullet drops in 7 to 9 inches. This works with very nearly any modern bottleneck cartridge, from 243 thru to a magnum. It works even better with your 7mm Rem Mag. Unfortunately its limited to three times power magnification.
The VX3 is a 1" scope instead of the VX6 30mm. I actually like that, as its less weight. The image quality and light transmission are entirely sufficient for any reasonable aniticipated hunting use I do....
it really boils down to value for dollar. What "problem" do you have that the VX5 'fixes"? What benefit do you get for the extra $500, $600???
