Hi all, I am in the process of trying to decide what scope to put on my 270wsm Finnlight. This rig will primarily be used for sheep hunting so weight is a concern. I have been looking at the Leupold VX3 4.5-14x40 with CDS system. This scope only weighs in at 13oz. I have 2 questions about this scope. First, for long range hunting is 14x too much magnification to not have parallax adjustment? Second, since this scope has a very small field of view even at low power, would the 3.5-10x40 be a better choice? Is 10x enough for shots 500 – 600 yards (with a lot of practice)?
