I have probably 15 scopes that I'm going to put thru their paces to see if they really do meet their specifications. Some Hawke Airmax & Vantage, Optisan EVX, SWFA SS, Centerpoint, Vector Veyron etc.
My first try was with a Vector Veyron 3-12X SFP mildot. The reticle is calibrated at 12X, so I shot some groups at 28.4 Yards measured with laser rangefinder. I moved the scope 4 mils up, down, left, right. The groups came out something like 3.7 mils on the reticle, but very consistent.
Now doing the math, 4 mils at 28.4 yards, comes out to just a hair over 4 inches at that distance. So I made a calibration scales in inches on my target. Here's what I found.
My Optisan EVX 10X44 was dead on with the reticle, as was my cheap Centerpoint 4-16, and my 4-12X Airmax
BUT,
My Airmax 4-16X, 3-12X, my SWFA SS 12X and the Vector above were all in agreement at just under 4", at 3.7" measured.
While fiddling with my 3-12X Airmax, I found that at 11X, it was dead on.
I know I need to do some more testing, but is it unusual for the reticle to be somewhat off?
The SWFA kind of surprised me, as I would think they were the real standard for mil dot reticles. Also, surprising was the Centerpoint being dead on. Of all the scopes I own, it is the true Amazing star. Not because it's the best, but because it came on an Air Arms MPR I bought used, took it off and set it aside (because, hey, they're junk, right?), decided to try it out much later and found that it tracks very well, positive clicks, and reticle right on, clearer than a lot of waaay more expensive scopes. I've shot the smallest groups out of that MPR with this scope and it just keeps keepin on, and I can't think of a single thing negative about it, and it was essentially free.
Anyway, this is my first go at mildot reticles and I'm trying to figure out why I'm not moving the correct amount. At further distances the error would be more pronounced.
