Well, I went to the range today and tried the new Vortex I just purchased. it's now mounted on a Rem 700 Varmint on an AICS chassis. After I mounted and torqued the scope, I sighted it in at 100. The lense was very clear. I can't really tell any difference between this scope and my Leupold mark IV. I had both scopes side by side...but then again, I'm not an expert and my 51 year old eyes are not 20 anymore. After I fired several shots and found the center of the target, I turned the elevation turret 1 mill. After I fired, I checked the bullet hole with the cross hairs and the bullet hole was exactly at 1 mill on the crosshairs. Then I turned the turret to 2 mills, and again the whole matched perfectly 2 mills on my crosshairs. Then, I turned it back to zero and fired. I hit the center of the target again. Each click was very positive with no wiggling as I turned the turret back and forth.
I tried this same thing several more times with several different elevations and every time I was able to hit the dead center of the target when I went back to zero. I'm sure there are better methods to check how repeatable a scope is, but I was honestly satisfied with the results I got today. Last night, I went outside and played with the illuminated reticle. It was very clear with all magnifications and the crosshairs mill numbers were not blurry and easy to read.
Honestly, my next scope will be another Vortex. I really liked it. I know this was not a very scientific review of the scope but I think I covered the basics.
Good luck with your new scope whatever you decide to get. The important thing is to go out there, make some noise, punch some holes, and have a great time!!!
Cheers!!!!
