Caliber is 6.5 Creedmoor. I was open on budget. I wanted to get a good scope.
I went into a local shop to look through scopes and play with the turrets. I checked out ZCO, Kahles, Nightforce and Vortex. I bought the Vortex Razor HD 6-36 gen3. because I got a smoking deal on the floor model. It was less than the new Europtic exclusive black version. Even at the regular price for the vortex, I could not see/feel enough of a difference to justify the extra dollars for the other brands. They're building a range a few towns over that will supposedly go up to 1800 yards. If true, there will be a new rifle and scope with my name on it for a retirement present in a couple of years. I'll re-assess then.
Vortex already came though for me. I did not realize that the flip cap for the eyepiece was not in the box. I wrote to vortex asking how I could get one and they immediately shipped a new set at no cost.
I went to the range yesterday to zero the scope. I'll admit that I had a tough time using their zero system. I like it, just wasn't used to it. I did not bring my sled. I had the rifle on a bipod. Holding the rifle steafy while adjusting the windage is apparently more than I am capable of... It took me a few more rounds than usual to get it locked in.
I really like this scope. I only shot at 100yds to zero the scope. Next weekend I'll test the tracking.
