I bought two of the VX-3 2.5-8x36 scopes three years ago, based on my experience with a 1982 Leupold 2-7x36 I have and still use and Mark4 8.5-25x50 Leupold. I predator hunt. The 2-7 power Leupold came on a 1982 Savage 243 I bought used several years ago. I added three more calibers for predator hunting. I setup the two VX-3 2.5-8 power scopes with CDS dials for the three cartridges. I have 204, 223, and 243 calibers with all zeroed at Max Point Blank Range (MPBR). If I have ranged the area ahead of time, the CDS dials or B&C reticles help beyond MBDR. I am hard on my equipment, not by intention it is just how I operate. These scopes have worked flawless and held zero. In predator hunting we will take the rifles in and out of the truck several times each day and carry them with all our gear going to & from the stands, so the rifle/scope is handled a great deal. These scopes have held up through all this handling, jarring Arizona washboard roads, being laid down on the ground repeatedly at each hunt stand as we setup and leave the stands, all the while trying to be silent. I needed to add another scope and tried another brand. The research had said the quality could be hit or miss, mostly very good. This other scope would not hold zero. It started out okay then went astray. After a few boxes of different ammo that normally shot very well with the VX-3's, I decided to ran a scope comparison at the range at 100 yards. The 243 55 grain and 204 Ruger 40 grain both hold normally hold a very tight comparable group with the VX-3 scopes. The new other scope was mounted on the 243, because that VX-3 scope was put on a new rifle as a backup to the other 204 rifle. This new scope had a max power of 18. The Leupold VX-3 at 8x holds a five shot one MOA group as always. My fliers make the group this size. The rifle and scope are always capable of producing tighter groups, as produced by my daughter. The other scope shot four and five inch groups at 100 yards. The other scope company was very nice about about returning or replacing their scope, good people. After the years of use in my hands the Leupold have become a trusted tool. I cannot afford to be a couple hundred miles from home on a hunt have a rifle loose zero or fog up on me. I recommend Leupold, and am looking at the D-EVO with my HWS as a new combination for predator hunting. Coyotes have the ability to be far away or right on top of you in no time with no warning in AZ. In many areas where we hunt, we take a rifle and shotgun. In these cases we are holding the shotgun with the rifle on a bipod at the ready. We also hunt from an A-frame ladder for better visibility in some areas. If I am holding a rifle the 2.5 power setting is a good starting point for close up surprises. In most cases I have a couple seconds to make things happen or the opportunity is gone. I have missed some because I needed more power than 2.5 power. I have missed some because the time to change power was too much and the coyote took cover. I hope to try the D-EVO to see if this can reduce my reaction time. If not I will stay with the VX-3 2.5-8 scopes and add a third to the 243.
