If you are using a muzzle velocity that has been recorded by either a Magnetospeed or Labradar and BC values that are set up as G7 multi-velocity configurations then we will assume these as correct. The most common reason that we see variations in predicted firing solutions and actual results in live-fire validation at 600yds is from customers using true MOA as their unit of measure instead of IPHY (Inch Per Hundred Yard) or Also known as SMOA or Shooters MOA. True MOA will raise your point of impact by 1.047" per 4 clicks at 100yds, at 600yds the 4 clicks equates to 6.282" of vertical point of impact shift.  With an IPHY/SMOA scope like the Swarovski Z3 & Z5 range, you would expect to move the point of impact up 1" per 4 clicks at 100yds, at 600yds the 4 clicks equates to 6" of vertical point of impact shift. So straight away you can see there is a .282" difference per 4 clicks for both these units of measure at 600yds. If your firing solution calls for a 13 MOA adjustment at 600yds the solution is expecting that your adjustment is going to shift the point of impact by  13 x 6.282" = 81.666" so if you only dial 13 SMOA your point of impact shift is only going to be 13 x 6 = 78".  That is a 3.666" variance in what is expected and what you might see.  Now to make things even more confusing, the majority of Z5 riflescopes that we have seen and tested will only dial .975" per 4 clicks at 100yds.  Therefore your live-fire results will most likely show a point of impact shift of 5.85" per 4 clicks at 600yds and not the 6.282" that your MOA solver was predicting. This equates to only achieving a 76.05" point of impact shift at 600yds.  That is a 5.616" variation in what your MOA solver predicts and what your live-fire results might show you. This is the main reason for your solver not lining up with live fire results. Do not be tempted to adjust the muzzle velocity or BC to compensate. We advise using Strelok Pro or any of the other ballistic solvers that provide the ability to use SMOA/IPHY and will allow you to modify the click value dimension to accommodate the .244" per click value that we are actually seeing in the Z3 & Z5 riflescopes.

A Z5-MOA-58-1REV Custom Scope Turret will replace the stack of three rings and will leave you with 13.25 MOA of elevation travel if you leave the factory zero stop in place.

Please find the rifle scope model you have in OUR PRODUCTS select the Personalised Custom Scope Turret - 1 Revolution option and fill out the required information in the data chart below, the more information you can provide, the more accurate your turret will be. For the most accurate turret we recommend that you upload your ballistic drop chart that you have tested on the range once you are at the check out.

It is extremely easy to install your Custom Scope Turret, you only require the Swarovski turret cap removing tool and your NEW Custom Scope Turret ring. It will take no more than 2 minutes to complete the installation.

With all of the Swarovski Z3, Z5 & Z6(i) riflescopes that have the factory zero stop installed you are actually limited to 5 clicks less than one full revolution of elevation travel. Yes, you are correct, to get more than one full revolution you do need to remove the factory zero stop. It is a very quick and simple procedure that not only offers the ability to dial more than 1 complete revolution up but it also allows the ability to dial down for more precision at shooting distances less than rifle zero. eg. For 100m target or varmint shooting I will dial my 200m zero Z6 on my .308 7 clicks down = .7 MRAD

HOT TIP: For management and confidence in your Swarovski rifle scope with the factory zero stop removed it is recommended that after zeroing the scope you count the number of clicks either below or above rifle zero to fully reach the bottom or top of the scope elevation adjustment. Record this number and direction on the side of your magazine or inside your floor plate and you will always have a reference to know how to get back to rifle zero should you ever be unsure in the future.

If you do not have access to a chronograph to measure your muzzle velocity it is not the end of the world. What we have done in the past is use the estimated velocities from the ammunition box to create a rough ballistic chart. We will then go to our shooting range and check that our rifle zero is correct, once confirmed we will shoot out to a range of 500-600 m/yds dialling up from what our rough ballistic chart says. Continue to dial the scope up or down until you get your group centred on the target at your chosen range. Record this data in MRAD, SMOA or Clicks and then use this as a correction factor in your ballistic app. From here you can continue to shoot out to further distances to validate the chart is correct. We have had great results doing this using Strelok Pro for Android or Strelok Pro for iOS Strelok Pro has a number of advanced features including Zeroing Weather input, multi-velocity Ballistic Coefficients, SMOA adjustment values for Z3 & Z5 scopes and even allows for scope tracking error correction. If you do not have a ballistics app that has this ability, you can send the tested dial-up data through to us after placing your order and we can do this for you.

The Z5 is a 58 click per revolution Shooters MOA based scope (AKA SMOA or Inch Per Hundred Yards / IPHY) so please look under the Z5 category for compatible Custom Scope Turrets. Different models of Swarovski scopes have different numbers of clicks per revolution. Z3 have 46 clicks per revolution, Z5 have 58 clicks per revolution, Z6(i) have both 50 and 58 clicks per revolution dependent on what scope model it is.

The Z5 3.5-18x44 P BT is a 58 click per revolution Shooters MOA based scope (AKA SMOA or Inch Per Hundred Yards / IPHY), the factory installed zero stop reduces the scope elevation travel to 5 clicks less than one full revolution. When you subtract these 5 clicks from the total 58 clicks required for one full revolution of the turret you end up with the 53 clicks of adjustment you are seeing.

The turret and/or the coloured rings do not restrict the scope to one revolution of elevation adjustment, it is the factory installed zero stop that reduces the scope elevation travel to 5 clicks less than one full revolution. By simply removing the factory zero stop you will gain access to much more elevation adjustment. If you mount your scope rings on a 20 MOA rail and match that with a Z5-MOA-58-2REV Custom Scope Turret and you will now increase your dial up from 13.25 MOA to at least 29 MOA of elevation adjustment.

For management and confidence in your Swarovski rifle scope with the factory zero stop removed it is recommended that after zeroing the scope you count the number of clicks either below or above rifle zero to fully reach the bottom or top of the scope elevation adjustment. Record this number and direction on the side of your magazine or inside your floor plate and you will always have a reference to know how to get back to rifle zero should you ever be unsure in the future. With a 20MOA rail installed, it is recommended to count the clicks below rifle zero and record that information.  If you are using a Z5 5-25x52 on a 20MOA rail your rifle zero should be within the bottom turn of the riflescopes adjustment so it is very easy to manage.
