BEST EXAMPLE I seen of all videos about how the zoom affects MOA at a distance,, THANK YOU very much Sir,,, NOW I understand, have a better grasp of MOA, ZOOM and not need to always use turrets,,,,,,, You are the man,,,,,

Finally. I was so sick and tired of hearing "second focal plane only works at the highest magnification." No, second focal plane works at any magnification if you do the math, go to the range and check for accuracy of your math. Thank you, sir for apparently being the only one on KZfaq that I have come across who seems to understand this.

Probably the best breakdown and examples I have seen of how magnification of a SFP scope translates to rounds on target. I just bought my first long range rifle and got a great deal on a scope, this is exactly what I needed to know and how to adjust, thank you so much, your videos are some of the best in the business!

This is perfect, I had a hard time finding information on this topic. Much appreciated!

This is one of the clearest how-to videos I've seen. The graphics (red arrows on the reticle frames) are a great help. Thank you

Thank you! Simple and straight to the point. Nice to know the mathematics behind this instead having expensive, but fun, bonding sessions with gear

Thanks for the video. Been shooting with scopes for 28 years and never knew this until a buddy told me about it the other day.

Outstanding break down, I had this issue this past weekend at half magnification and was trying to figure it out. New shooter so very helpful!

BEST EXPLANATION VIDEO!! THANK YOU SIR!!

Thank you for this video. I clear did not understand to utilize a scope.

Thanks for taking your time for the demo. I wanted to use this information to adjust holdover for windage. I just discovered my scope doesn't have windage Holdover, so it's my best guess or use MOA dial. Awesome video.

Great video. Very helpful

Awesome explanation, how would you go about calculating for powers other than half?

So good this is exactly what I’ve been looking for. Seems like the more you dig in reference to scopes the more you uncover and it can be frustrating. Is that double MOA the same on most scopes with RFP from full to half?

This is why grandpa said to sight in your rifle at a magnification you’re comfortable with and never fucking touch it…

Good idea. Get DOPE on full, half, and lowest magnification.

Thanks for the video mate! I just picked up my first second focal scope and I’m so confused! It’s an Accura 5-30x56 and mine says 1-1 at 20x with no other info so I don’t get what I’ll be at when I’m at full magnification!

Great video do we need to convert to M.O.A if we are shooting M.R.A.D, or can we just double the calculations at 1/2 power as with M.O.A. ?

Nice video

Great video. Does this "calculation" also apply to MIL reticles in SFP optic? I got a Konus ABSOLUTE 5x-40×56 for testing. The subtentions are .5 MIL and my particular ammo is 1.5 MIL at 300m. If I go to 20x mag, would I need to hold it at 3.0 or .7 MIL for same POI? I'm more aquianted with FFP (1-10 LPVO) so I'm trying to wrap my head around this.

Love this video! Quick question, if the turrets are set to .25 MOA adjustment, do those need to be re-calibrated depending on what power you are on? Example being click = .25 MOA at full power and low power, or is it a click = .25 MOA at full power (12) and .75 at low power (4)?

how will this math work with a mil dot sight? would it still be twice the hold?

By having half magnification on a 3x9 scope, does this also change my 100 yard moa of 2, 200 yard moa of 4, 300 yard moa now being 6?

So would your moa at 6x magnification be 3x and The 5 moa in the reticle would represent 15?

I prefer first focal plane so you don't have to worry to about your hold overs changing. Downside is the reticle is tiny on minimum magnification and can be hard to see in low light.

Do the same rules apply if I dial elevation? Example, if a 1000 yard shot calls for a 30moa holdover, if my scope is set at 1/2 power would I dial to 15 or 30 moa?

on optics 3-9x44 will still be applied. and is that only mid to most powerful.THANKS

Just getting into big game hunting and I didn't really understand why hunters would use SFP if you weren't using full magnification, good video though does a good job of explaining how a SFP works. Now you have me wondering though. Most rifle scopes I've seen, including mine which is a SFP, have dials for the elevation and windage where each click of the dial is 0.25 MOA change. I would assume it is 0.25 MOA at full magnification? If so, then at 1/2 magnification, would that same single click be 0.5 MOA?

I understand perfectly what you are saying. Well said! However im confused... does it matter at whatever magnification you have set on your scope do the crosshairs stay constant (lets say you have a traditional 100 yard zero) or does that shift the point of impact too? I hope this makes sense..

Does this also appy to a first focal plane scope? Also I see you're doing holdovers however, if your turrets are dialed for a specific distance, does the half power (12X) rule still apply?

What about parallax adjustment

I’m guessing that this is the same for windage?

Half power also has a larger exit pupil thus brighter image in low light.

So what would be the ideal zero for a SFP optic?

This makes me more prone to buy a fixed magnification scope :D

I also noticed the bullet hit farther to the right. Assuming you didn’t jerk the trigger, could this have been caused by the sfp dial?

So Half magnification you double the MOA; when you’re at the least magnification do you times it by 4?

the first focal plane of the optics would not have such deviations? would the location of the hits be the same at any magnification?

I scope my deer at low power to determine size and I aim. Once I have my aim I change to full power to take my shoot. While this never fails me is it wrong to do it this way?

Two quick questions: 1) does this only apply to hold over or also when I dial in? Let's say I zeroed my Rifle using half Power at 100 yards and now I have to use full Power while hunting. Does that mean I need to dial up only half of what's needed? 2) What if I need less than Half Power? Let's say magnification at 0. For example there's something 10 yards in front of me? Thanks for any feedback!

What scope is this

What if you're not at full or half magnification?

So if I’m at the lowest magnification my sub tensions would multiply by 4? Correct?

The reason why I dislike SFP scopes, that are so common in europe that you don't really see FPP sights for lower price range. It doesn't make much to do the math, like going from 4x to 8x as you just double or divide things, but that really works only on the range, not on the faster situations if such accuracy matters. But considering that you rarely shoot over 25-50 meters for moose, deer etc as you don't have a sight on them, it doesn't matter and why SFP sights are so common as you get clearer image and reticle. With FFP scopes it is just nice to know that your sight markings can be used without thinking math. I just wish that we really would get to affordable levels already with the "smart scopes". As in digital computer adjusting the sight. So have a button to measure range to target with laser, computer measures the cant constantly, but will measure the pitch angle on time of range measurement. And then show the impact point based to that data. For the wind, I think it could be done by just estimating and inputting the value there, as adding laser to measure wind speed from dust particles becomes too expensive. And of course all this would be done by your own chosen cartridge for your gun in the range, so you shoot the group, move the dot on impact point and save the cartridge to the sight. And if having 3-5 cartridges memorized for 10-20 different range values, it would help a lot. As bonus, have the temperature measured as well, as that is cheap and easy thing to add there. I think a Chinese company could easily make these sights for even sub 200-300 price range if really put some effort. And I know that so many airsoft shooters would really love such things, and even more some smaller caliber users. There is the open source Linux based smart rifle, but cost is almost 20 grand... You can even just mark the point where you want to hit, and then scope tracks the target and you just need to move the crosshair on that mark by holding trigger and it will automatically fire when sight is on place.

With a 4-16x50 I would put it on 8 and where I’m holding would be a couple of MOA higher than I would be at 16?🧠🤯🔫

So why can't I just site in on half mag. And be good for both full mag. And minamin mag.???

should've shot the 24x at 2moa hold, and then shoot the 12x at "what-appears-to-be-1moa" hold and see both shots impact the same point.

Half magnification shoots higher….thanks

Liked the vid, just because, However, NOT a good explanation. What yardage are you zeroed ? What about the effects on the actual crosshairs ? SFP = crosshairs, stay good ant any magnification and only the sub tensions change ?

Me realizing I was shooting into the sky at 1x at distance.

It makes no sense that they make a scope like this

realistically,out to 300 yards, none of this matters and you just hold over the correct amount. Naturally you need to know your ballistics well.

This is the most confusing video I have watched this doesn't explain how to zero the optic or how to use it in the field
