Ill just give a little update here. I did buy this scope, a Vortex Viper 6.5-20x44PA. $279 @ Cameralandny. I do have a couple gripes with, which ill go over,but in general I am very pleased with it.
First gripe and my Main one. The parallax knob is not exactly right. And my friends is the same. If you then it to the yardage you're shooting the field of view is clear but it is not parallax free. 500 yards and in when you adjust it to be parallax free it is some fuzzy but still close enough to shoot. Past 500 it compiles some and is fuzzier when set parallax free. But seeing as how most of my hunting shots are 600 and less I manage. Banging steel further than 500 I set it so it is ALMOST parallax free but field of view is clearer. This works but obviously groups will not be as tight as they possibly could be.
Gripe two. The 30 mm tube either is somewhat lightweight or the erector mechinism fits very snug. When I first got the scope I mounted it by hand as I usually do all my scopes. Just a straighter driver and tighten screws by feel. When I did this the scope did not track well. It was very jumpy when dialing. I called Vortex and the first thing he asked was if I used a torque wrench. He said if over tightened it will bind the mech. So I ordered a wheeler eng. set and lapped the rings perfectly and mounted with the torque wrench to perfect spec. Now the scope turrets work perfectly. Imagine that. Oh, another mini gripe I guess is the pick up to zero turrets. Yes it's fast to zero but I would rather have a screw on turret so I could install zero stop shims.
So in conclusion I would definitely by this scope again and probably will if I see them at this price again. I love the wide plex reticle. It blocks very little of your field of view. The scope is very solid and precise now that its mounted properly. I can shoot a one hole group dead nuts at 100. Turn and dial it to 500 and shoot a sub 1.5" group dead nuts on the bullseye. I've dialed a little further and put first round hits on clay pidgeons out to about 650. Very pleased with the scope at this point.
