The Zeiss ASV+ is a great improvement of your Zeiss scope. It can turn your hunting scope into a great long range hunting or shooting scope. The ASV+ lockable feature will prevent it to change zero by accident, with one of the 9 rings you can have a custom turret for almost every caliber and hunting situation (with some limitations that we will see later on Choosing the proper ballistic ring). The zero stop function of the Zeiss ASV is a must have for hunting, so you can always return reliably at your zero distance. 6.9 mrad of compensation will give you the ability to compensate to ranges that most of hunters would not even think to shoot at. For example my .300win mag with 190gr bullets at 900m/s can reach out to 850m with 6.9mrad.

Zeroing a scope with Zeiss ASV+

Zeroing a Zeiss ASV+ turret is really simple but there are a few tricks to do it properly. First we have to know that the Zeiss ballistic turret has a spring and we have to pay attention to hold it with fingers during unscrewing the upper screw. Than it is easy to zero. For low shots we turn the Zeiss ASV turret clock wise, for high shoots we turn it counter clock wise. The markings on top of the Zeiss ASV turret for sale are: 1click = 1/3MOA/1cm/100m >UP/H. Which means that with one click we will move the bullet impact up for 1cm/100m if turned CW. This is actually a MRAD scope which means that one click represents 1/10 of MRAD angle (this is what we want to insert in our ballistic software). Next thing to check in our so-called Zeiss ASV manual is that we properly adjusted the zero stop function. There are two pins. One is on the scope body and the other is on the internal adjusting ring. They are properly put together if the upper pin is left of the lower pin while looking from the right side of the scope. To have the full Zeiss scope adjustment range the pins must touch themselves. Watch the video at the bottom for better understanding.

Ballistic ring selection

We have 10 different ballistic rings marked from 000 to 009. The first Zeiss ASV ring selection marked 000 is the normal MRAD ring with markings from 10 – 60. This marking on the Zeiss ASV rings actually represent the number of clicks. If we want tu use this ring we enter in our Zeiss ballistic software that our scope clicks are 1/10 mrads(not 1/3 moa). Then each marking means how much clicks we have applied and lets say that if we applied 20 clicks this is 2 mrads or 25 clicks 2.5 mrads. With this ring we can calculate our drop on the field at all conditions and with any caliber — a very simple Zeiss ASV calculator.
With Zeiss ASV+ rings that are marked from 001 – 009 the story is different. This are custom ASV Zeiss rings and the markings 1 – 6. This numbers represents our zero in meters multiplied by 100. So the marking 1 means our zero at 100m our 3 at 300m and so on. We also have points in between this numbers which means half the distance between numbers. So the point between 3 and 4 is actually our zero at 350m.

Now that we know what is the purpose of those ring lets see how do we select the proper one. There are  ways that I will describe:

1. Choosing the ring number 000 and use it with our ballistic software. This actually requires us to measure our V0 velocity, put all the data in the software about the bullet BC(read G1 vs G7 BC), rifle and so on. This is the most precise way of calculating drop which can be used for any weather or at any altitude and will enable us to shoot at farther distances.
2. Measure our  V0 velocity and insert all the data in the Zeiss ballistic calculator. In this way we will get a ballistic table and the number representing one of the rings (001 – 009). Now with this ring we can shoot at those distances marked on the ring, but it will be only precise at the weather conditions and altitudes that we have put in the software and the Zeiss ballistic calculator. If for example we have entered the altitude 0(sea level) in the Zeiss ASV ballistic calculator and then we go hunting at an altitude of 1000m, the bullets will fly higher which can make us miss the target or even worse, to wound an animal. So the rings are precise only at the same conditions that was put in the software. I highly recommend to check this ballistic ring zero at different markings in the field (a ballistic calculator Zeiss will come in handy).
3. If we don’t have a chronograph we can still choose from the factory ammunition in the Zeiss ballistic calculator and only insert the weather data and altitude. During the Zeiss V6 test, this method is less precise and needs some more shooting in the field to check our zero at different distances. When using the ballistic calculator Zeiss, be aware that things can also change between ammunition LOTs.

ASV Long Range and ASV Competition differences from ASV+

Since the introduction of the V8 line of the Zeiss Victory scope, you can see that they have a ASV Long Range and ASV Competition turrets. The only difference between the ASV+ and ASV LR is that the ASV+ has a total range of 6.9 mrad and ASV LR has a range of 10 mrad(100clicks of 1cm/100m). The ASV Competition turret is the same as the ASV LR turret, but the clicks of the Zeiss Victory V8 4.8-35×60 are of 0.5cm/100m so the ASV Competition turret has only 5mrad of vertical adjustment. This is because there are still 100clicks in the ASV turret.
