Hello, everyone, this is Marcos Paulo from MPLA Airguns UK.
And today we have the Complete Tutorial of Strelok Pro (Part 2 of 2).
Stay tuned, something good is coming!
Let's go over these 8 buttons we have in the bottom.
The first button: Moving Target.
To calculate, you have to inform the speed of the object, your target. Click on Calculate, and it gives you in MOA or MRAD, the difference for you to aim in the direction of the target, lateral or frontal.
So when you shoot, the target will keep moving and you can hit the target.
Next button: Additional Data.
They are simply the information calculated based on the data you are using at the moment.
Velocity, corrected to the current temperature because sometimes the difference of temperature can affect the shooting. It remains the same.
Retained velocity, is the velocity of the pellet when it hits the target, at 70 meters.
Sound speed, usually is constant, 346m/s. It may vary a bit because of the difference in atmospheric pressure.
Time of flight, in seconds, is 0.3 sec. It means that in 0.3 sec, the pellet will leave the muzzle and hit the target at 70 meters.
The value of the click, the estimated value of the click, at the distance of 70 meters, will adjust in 0.5 centimeters. So, each click will be equivalent to 0.5cm.
So, if you hit there, and want to hit a bit up, for example, 1 centimeter up, so you would use 2 clicks.
Trajectory height, in meters. In other words, how much the pellet will go up in its trajectory. So, 0.2 up.
Vertical deflection of crosswind and spin drift, related to wind deflection and wind gusts, during the trajectory of the pellet.
Coriolis Effect, I can explain on another occasion, but for Airguns, the Coriolis Effect is so so so, insignificant, that it does not worth to be mentioned here.
It is not calculated here, and you can see it here, for example, and it is zero because it is very little.
Target list. How does it work? Let's suppose that you shoot always from the same place, here, for example, you have…
… a pigeon flying over there… LOL…
But let's say that from here I use to shoot a pigeon at 20 meters and at 40 meters, here, in the UK.
I can grade and record these information, pre-defined, in this list. This way, when I come to this list I can know exactly,
Which is the elevation and windage (lateral deviation), for each one of these pre-defined distances, and targets.
I could have Grey Squirrel, Pigeon, a Canadian Goose. Other things that we can shoot, a can, a beer bottle. No matter what, I could add it here.
The Shooting Table. Let's go first to the configuration. Which information do I want my table to show?
This type of shooting table is quite famous. Some people print it to different zoom magnification and the wind and take it to the field.
So if they are shooting a certain target, they can use one table or other.
I usually keep all that information available. I will set the start distance to 25 meters. The end distance to 150 meters. It is more than enough.
Step distance, which is the differences (steps) of the distances. Let's put it 10. And adjust the start distance to 20 to make it easy.
I will start at the distance of 20 meters, to the distance of 150 meters, that is usually the range for Airguns. Sometimes it is close, so you can start at 10 meters, for example.
And each 10 meters. So, it starts at 20, then 30, 40, 50, successively.
Bullet speed, bullet energy, flight time, corrections in centimeters, corrections in MOA, corrections in MRAD, corrections in clicks. I saved that.
The table gets much more complete, you can see it. All the information.
So, if I am shooting at 20 meters, the pellet will get there at 242m/s. It left at 265m/s and will hit the target at 242m/s.
It will also get there with 34 joules of energy. Time of flight 0.08, and so on.
What is the vertical correction? "U" means "up", so, 0.4 centimeters up. Correction in MOA 0.7. Correction in MRAD, 0.2. Corrections in clicks, 2.7 up.
You can send it by email. You can generate an XLS (MS Excel file) for you to print or work in this information.
The button with a gear is the main configuration of the app.
Powder temperature. SMOA instead of MOA, which is a specific unit of US Army, used mainly in the US. It is not much used by us.
Vertical deflection. I do not use it because this is related to the wind from up and from down.
Add spin drift, which is the rotation of the bullet in the location you are shooting. It does not matter for Airguns, once it is for extreme long-range shooting, more than 1000 meters.
Add Coriolis effect to the results. When you shoot from East to West or West to East, you have more of this effect, but for shots that take more than 1 or 1.5 seconds to hit the target.
Airgun shots take 0.08 to 0.3 seconds. It is very little.
Use "Up / Down" and "Left / Right", instead of "+ / - ". It is up to you, you can change it.
Use the camera to find the slope angle. It means that you can use the inclinometer of the camera of your cell phone to give you the angle.
Measurement Units, language and Bluetooth drives that you can add, to share and receive information.
The next, MOA < > MRAD, gives you formulas for calculating distances. You can use, for example, the difference of your target, in centimeters, a pigeon has approximately 20 cm.
And you inform the size of your target on the reticle. Then it will calculate the estimated distance of that target, based on that the real target has 20cm and it uses 5 dots of your scope.
So it estimates the distance of the target based on that information.
The MOA at Distance is basically to make that calculation I mentioned (Part 1), from MOA to MRAD or MRAD to MOA.
The next button is for you to connect Bluetooth devices. It is not our case now.
The last one, is basically, a reverse calculation. So, given that you inform a pellet, a weight, a velocity and a Ballistic Coefficient, it calculates the results.
In this session, you give the results and it calculates to check if the Ballistic Coefficient previously informed is correct. Basically, the reverse calculation of the ballistic calculation.
You use the velocity information to find the real velocity. And ballistic information to find the Ballistic Coefficient.
A very important thing here that I did not mention yet. The button reticle, that is the main function of the app.
You see that the configuration of this image is since 8x zoom, which is the minimum magnification informed, up to 32x zoom, that reflects the scope information.
Note that the reticle is exactly the same of the Hawke Sidewinder. You see that the zero was made using the 20x zoom.
So it gives you the aiming point. See that the yellow point is the point of impact of your pellet.
So, you have to count, 1/2 Mil Dot to the left and 2.5 Mil Dot to up, to hit a pigeon in this distance, given a certain wind and a zero distance of your scope.
If you change the zoom, you will have to make a bigger compensation. You can play with this information, to see the compensation you have to do for each one of these values.
You can export it to PNG (Image file), that is this first button bellow.
The configuration of the scope shows that it was zeroed at 20x, I'll let it in 20x. This is the basic configuration of the scope.
The next button below. You see that I have a pigeon as a target. But let's say that I shoot in a rabbit.
When I come back, I will see the image of a rabbit. And if I do not shoot in rabbits, but I want a round target, I can also select the size of the target.
For example, a USBR target, let's say that it has approximately 6cm. When I come back it shows a rounded target.
Note something important. On the top of this image, you see something similar to a turret of clicks in a scope.
So if you go back to the main screen, you see your scope if it is in MOA.
And you see here vert MOA = 9.1. So what does it mean?
If you go to the reticle and turn the turret to 9.1, look what happens.
It gives you the information of how many clicks (MOA), you should have. Considering that your turret is zeroed.
How many clicks (MOA) you should have for the target to move to the center of the reticle.
Ok, guys?
It is a very versatile app. Now with that information, you can start playing and using it with more knowledge.
I hope to have helped you all.
