I had the v6 first and after pulling my hair out trying to get my ballistics to match my long range impact I did a tall target tracking test.
It failed miserably and the calibration error was not consistent through the elevation range.
It was my first time experiencing tracking issues and really opened my eyes.
The v4 I tried a few years later after all the awesome reviews, I had the same issues with impact not matchingy ballistics and did the same tall target test with similar results.
I realize every one can produce a lemon now and then but I just can't trust zeiss after that.
Also they only have a 5 year warranty on their scopes!!
Doesn't make any sense if they're so reliable
Amazing how people get different results from small sample sizes like ours. I believe my V4 and V6 count is relatively high though compared to most users.
I’d be curious to know what all is involved with your tall target tracking and how you measure it.
Here was my testing method. Ran these tests close to 2 years ago now and need to dig up the results.
Here’s a very quick description of how the test goes...
I verify all of my scopes at my office where we calibrate our total stations. They go through this procedure before they ever go onto a rifle. I’m able to verify accuracy at (0.5 +1ppm xD) mm. That’s using the latest ISO spec for accuracy. So any scope that goes onto the calibration station will be tracking against a “perfectly” measured verification tool.
I have created and measured in a tracking verification sheet using the total station. The scopes are then leveled, measured, and zeroed onto the center of the sheet at exactly 300 feet. The scope and tracking sheet are both measured in to be perfectly aligned horizontally and vertically. After the center of the sheet and the center of the reticle are aligned, and it has been verified that parallax isn’t effecting the outcome, zero is then set on the scope.
Finally we get to spin some turrets. I’ll start with small movements both horizontal and vertical with returns to zero. I then start stretching the turrets out to some larger distances. I keep track of clicks very carefully in each direction and writing down results.
People forget to realize that 1 MOA at 300 feet is 1.047" meaning the scope adjusts 0.261" with every click of the turret on a .25 MOA per click turret. Most homemade “tracking boards” aren’t measured in correctly and scarily, a lot of guys use shooting the rifle for verification. This is okay for a quick verification but not to accurately test if your scope is tracking correctly. Guys who don’t shoot and just use the scopes (better method) often do it in an environment where they haven’t been properly leveled, properly measured in, and checked for parallax issues. So you see a lot of guys claiming a certain scope “doesn’t track” but have zero verifiable data to back up their claim.
I’m a huge proponent of doing my own research for my own gear. Reading on the internet can help, but you gotta test your own gear for how you plan to use it.
