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 TH-cam that I have come across who seems to understand this.
Yep. I always pick a mid range magnification and do my own personal drop chart. I am a hunter and only shoot targets at hunting ranges but when in the field I like to carry at different magnification based on the terrain and coverage. Tight quarters? Then 3x Mid range or some tight spots? 6x. Sitting over a meadow or hill side where it’s gonna be 100 yards or more? Then 9x BDC works as called out when in 9x and I have the numbers for 6x memorized. 3x is only used in tight quarters and it’s a straight shot no BDC required “Won’t work” and not calibrated are 2 different things
What they mean by sfp only working at one magnification is that the hash marks are only true at one magnification. Meaning there's only one magnification where they don't require a conversion. Calm down.
This video really helped me understand what I've read about the difference but showing it in a practical exercise. Really is helpful and much appreciated.
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!
Good demonstration of this. I have a Vortex HST 4-16 SFP scope. On its magnification ring, there are only references at 16x, 8x, 5.3x, and 4x in order to simplify the math when applying this concept. 8 is 1/2 of 16, 5.3 is about 1/3 of 16, and 4 is 1/4 of 16. So if my shot calls for 3 mils and my magnification is set to 8x, I would hold 1.5 mils (1/2 of 3 mils), if my magnification is set to 5.3x, I would hold on 1 mil (1/3 of 3 mils). It works well.
Very good, my first scopes in the 60's were ffp , was so much better for hunting when I believe Burris figured out sfp , I have no idea why anyone would want ffp for hunting
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?
@@OutdoorSolutionsI like in your videos you demonstrate half power SFP shooting. I bought the Zeiss 4-16x50 #68 reticle based off your videos. 8x is PERFECT for 250-500 yard shots on game. I shoot every week and got my 1/2 power sub tends memorized. Only time I crank to 16x is sighting in at 100 yards and fun shooting steel at 1K
I the first 30seconds you said "we'll leave a link to it in the description" concerning your video on "first focal plane versus Second Focal Plane". I am familiar with both but was looking for your "LINK" in the description to see your take and explanation of the two. Unless I just am not seeing it, I think you might have forgotten to leave the link. I see a link for shooting w a tripod, no tool bore sight, field to table and long range shooting school.
So, pretty much place target on same reticle mark regardless of magnification. Just jave to know what magnification youre on so you can call it x2 or x3, etc
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)?
Thats awesome, we are glad you found us. We are always happy to answer questions if you have any. We also offer hands on instruction at our classes if you are interested. @@kylejackson7532
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!
Your subtensions will continue to change, so now you have to do even more math, which can get really confusing when you are going beyone the 1-1. Your 2x subtentions will be at 10x with that optic
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?
Great question. If it’s in 1/4 MOA clicks, it’s always the same no matter what magnification. The only thing that changes is the sub-tensions in your reticle
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..
Looks like you answered ur own question and we are actually doing a short video on that right now. But now magnification does not matter for your crosshairs.
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.
@@OutdoorSolutions an illuminated reticle is the way to go. I have a primary arms 3-18 and the Illumination is useless during the day but in low light it makes a huge difference. Another nice thing with some primary arms reticles is they put a horseshoe around the aiming chevron. On min magnification the horseshoe can easily be seen.
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.
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?
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.
@@OutdoorSolutions Most things are done anyways in China, even the 4000-5000 dollar optics and cameras, that don't cost anywhere near to produce at that price. Example my optic that cost 21900 USD, costs to manufacturer to produce only about less than 4000 USD. Sure it does perform far better than a 1200 USD optic, but difference is negligent that only 5% of the time you really get the benefit for it. Sad thing is, you can be almost as effective most of the time with a 140 USD one... The point is, the electronics and code doesn't really cost much for a mass production. One can already do crazy things with a 5 USD arduino board. Question is more that there is only the couple commercial sights out there, and then some crazy military industry prototypes and ideas, but otherwise nothing to really push simple tech forward. Like alone just having a computer to adjust impact point inside scope (a red dot or something) based shooter optically adjusting collimator ranging would make many very happy, even if required to manually adjust estimated windspeed. Like go to shooting range and lock rifle on table, shoot at the 50 meters, 100 meters, 300 meters and on each range move the dot on impact point and record the range and position for that. Let the computer perform the extrapolation between ranges then. Very simple computer system and would help a lot of people.
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!
Magnification for your zero does not effect holdover or dialing. If you have something as close as 10 yards you might have to consider your scope offset but that’s it.
@@OutdoorSolutions Hey thanks for the swift reply. OK let me ask it this way. If im at let's say im holding over at 250 yards and I need to come up just for example 4 MOA. On half power that would be 8 MOA.. Now if instead of holding over I want to dial it in do I dial 4 or 8 MOA?
@@Reaper-3000 Your dial will always be accurate no matter what magnification you are on. SFP only has to do with the sub tensions in your reticle not the dial. Hope that helps. :)
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?
Great question. Does NOT apply to FFP, which is one of the advantages of FFP. If you dial for your elevation it does not apply. If you dial partial elevation and still need to use hold over yes it would apply. Hope that helps. Actually gives a good idea for a new video.
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?
That depends on the caliber and velocity you are shooting. Also your shooting style. I don't like to fool around spinning dials or using range finders when a nice buck is in sight so I sight in deer caliber rifles 2600 to 3000fps so the top of my groups are 3.5 inches high at 150 yards. That makes hits from zero to 300 yards a simple aim and shoot proposition.
Great question. Point of impact does not change when using center crosshairs for zeroing your rifle. Magnification does not matter until you start using your reticle for elevation and wind holds.
@@fishlife1013 not 100% sure if I understand the question but your zero stays the same no matter your magnification your DOPE chart will still be true but you will have to adjust to any changes in your sub-tensions if you change magnification. Hope that makes sense or answers your question.
Could 100% matter at 300 yards. If you’re on 50% magnification at 300 yards, and don’t calculate for double sub tensions is enough for a complete miss or a wounded animal. With a 6.5 Creedmoor your hold is 4 minutes (12”) at full magnification if your at 50% the same hold is now 8 minutes (24”) causing a complete miss or a wounded animal.
@@OutdoorSolutions my point was to ditch the crutches in the scope and know your ballistics for hold over. At longer yardages maybe start using the little crutch lines in the scope ? If i know my bullet and ballistics there is no reason to use the little lines as a crutch, it's not hard to actually know how to shoot. I know my bullet is gonna drop 12 inches ? So I hold over 12 inches. Scopes don't account for windage, you actually have to know how to shoot. 10 MPH wind, maybe hold 4 inches against the wind or whatever it is.
@@OutdoorSolutionsI about did this today and it’s what brought me to your video and I still don’t quite understand why I missed other than I need to get a FFP scope. I have a Rugar American .308 with a vortex crossfire 2 6-18x44. I have it zerod at 100 yards at full 18 power, it will shoot quarters at 100. I go to shoot a doe today at 234 yards, I hold a tad higher about half way up on its shoulder, and I squeeze the trigger nice and smooth, no shake, I didn’t even have buck fever, and some how I missed, and this is twice this has happened to me. I really think it’s something I’m not doing with the scope, because this kinda shot used to be a chip shot for me with a .30-06 and a leaupold FFP scope. I’d also like to note that I had the gun rested on the fore end of the stock on a hay bale, not on the barrel, and my scope is tight on the gun and the base isn’t loose either. Any advice or help would be greatly appreciated, this video helped some but a lot of it still went over my head simply because it just sounds like a lot and not something I want to deal with when I’m hunting. None the less, I reckon the next chance I get Ima have to go spend some time shooting and seeing how it groups out to ranges other than 100 yards.
We appreciate your observation but don't agree with the "crutch" comment, it is a tool to make you more proficient. If you have a line that you know is one MOA at any given distance, it is simply giving you a measurement for your hold over instead of guessing what 12" looks like at any given distance. With this method you still have to know and understand your ballistics @@jeffhays1968
@@OutdoorSolutions You see, after several decades, I don't GUESS what 12 inches, or 18 inches or 6 inches looks like. I know precisely what they look like. I feel at or under 300 yards technological "help" ( I'll not use the other word ) is A not needed and B lazy. AND as you stated easy to screw up a shot with. I'm sticking with that.
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 ?
@dddur13 well you would think naturally a good field tip would be how to zero the optic and how to use the zoom and understanding the functions and it doesn't exactly make it clear

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. ?

Found an answer: Unless your scope is broken, changing the magnification by zooming in or out will not change the POI of your bullet down range.
Looks like you answered ur own question and we are actually doing a short video on that right now. But now magnification does not matter for your crosshairs.
This makes me more prone to buy a fixed magnification scope :D
Really? In what way? When you say fixed, you mean just a single power not adjustable?
Why not use the crosshairs as intended rather than the bottom?
simply buy one with plain crosshairs and no hash marks, I like them best anyway, simply hold a bit higher

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!
Magnification for your zero does not effect holdover or dialing. If you have something as close as 10 yards you might have to consider your scope offset but that’s it.
@@OutdoorSolutions Hey thanks for the swift reply. OK let me ask it this way. If im at let's say im holding over at 250 yards and I need to come up just for example 4 MOA. On half power that would be 8 MOA.. Now if instead of holding over I want to dial it in do I dial 4 or 8 MOA?
@@Reaper-3000 Your dial will always be accurate no matter what magnification you are on. SFP only has to do with the sub tensions in your reticle not the dial. Hope that helps. :)
@@OutdoorSolutions Thanks for the info. Makes sense now!
@@Reaper-3000 Glad we could help
So would your moa at 6x magnification be 3x and The 5 moa in the reticle would represent 15?
On the 6-24 it would be 4x and 20. Thanks for your question and thanks for watching.
how will this math work with a mil dot sight? would it still be twice the hold?
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?
Great question. Does NOT apply to FFP, which is one of the advantages of FFP.
If you dial for your elevation it does not apply. If you dial partial elevation and still need to use hold over yes it would apply. Hope that helps. Actually gives a good idea for a new video.
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?
Why do you have a 100 yard MOA of 2?
On second focal plane do you personally always zero at full mag?
@@LoneStarRay yes but that’s a personal preference and not necessary
Nice video
Thanks
What scope is this
ZEISS Conquest V4
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?
If it never fails, I wouldn’t stop. Shooting at full power on most SFP optics is where your sub-tensions are true.
What if you're not at full or half magnification?
More math, which is the advantage of FFP
What about parallax adjustment
Hey Tony, what is your specific question about Parallax adjustmen?
So what would be the ideal zero for a SFP optic?
Not necessarily FFP vs SFP for zero, we recommend 100 yards but the most important thing is to be consistent with all your rifles for set up b
That depends on the caliber and velocity you are shooting. Also your shooting style. I don't like to fool around spinning dials or using range finders when a nice buck is in sight so I sight in deer caliber rifles 2600 to 3000fps so the top of my groups are 3.5 inches high at 150 yards. That makes hits from zero to 300 yards a simple aim and shoot proposition.
So if I’m at the lowest magnification my sub tensions would multiply by 4? Correct?
Correct
For your elevation or wind.
I’m guessing that this is the same for windage?
Yes same for windage.
@ omid jahromi
دکتر جان میتونید همچین ویدویی رو به زبان پارسی بسازید؟ خیلی میتونه کاربردی باشه
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?🧠🤯🔫
It would be double whatever your sub-tension is at 16 power.
So if your first hold is 1 MOA on 16 power it will be 2 MOA at 8 power. Hope that helps.
Half magnification shoots higher….thanks
for anything below the crosshair.
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.
that's a great idea, we will try that for another video and let you know when we post it.
Me realizing I was shooting into the sky at 1x at distance.
LOL, it happens
So why can't I just site in on half mag. And be good for both full mag. And minamin mag.???
Great question. Point of impact does not change when using center crosshairs for zeroing your rifle. Magnification does not matter until you start using your reticle for elevation and wind holds.
@Outdoor Solutions so does that mean I can use my dope card to adjust and still maintain my zero when I adjust my elevation or windage
@@fishlife1013 not 100% sure if I understand the question but your zero stays the same no matter your magnification your DOPE chart will still be true but you will have to adjust to any changes in your sub-tensions if you change magnification. Hope that makes sense or answers your question.
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.
Could 100% matter at 300 yards. If you’re on 50% magnification at 300 yards, and don’t calculate for double sub tensions is enough for a complete miss or a wounded animal.
With a 6.5 Creedmoor your hold is 4 minutes (12”) at full magnification if your at 50% the same hold is now 8 minutes (24”) causing a complete miss or a wounded animal.
@@OutdoorSolutions my point was to ditch the crutches in the scope and know your ballistics for hold over. At longer yardages maybe start using the little crutch lines in the scope ? If i know my bullet and ballistics there is no reason to use the little lines as a crutch, it's not hard to actually know how to shoot. I know my bullet is gonna drop 12 inches ? So I hold over 12 inches. Scopes don't account for windage, you actually have to know how to shoot. 10 MPH wind, maybe hold 4 inches against the wind or whatever it is.
@@OutdoorSolutionsI about did this today and it’s what brought me to your video and I still don’t quite understand why I missed other than I need to get a FFP scope. I have a Rugar American .308 with a vortex crossfire 2 6-18x44. I have it zerod at 100 yards at full 18 power, it will shoot quarters at 100. I go to shoot a doe today at 234 yards, I hold a tad higher about half way up on its shoulder, and I squeeze the trigger nice and smooth, no shake, I didn’t even have buck fever, and some how I missed, and this is twice this has happened to me. I really think it’s something I’m not doing with the scope, because this kinda shot used to be a chip shot for me with a .30-06 and a leaupold FFP scope. I’d also like to note that I had the gun rested on the fore end of the stock on a hay bale, not on the barrel, and my scope is tight on the gun and the base isn’t loose either. Any advice or help would be greatly appreciated, this video helped some but a lot of it still went over my head simply because it just sounds like a lot and not something I want to deal with when I’m hunting. None the less, I reckon the next chance I get Ima have to go spend some time shooting and seeing how it groups out to ranges other than 100 yards.
We appreciate your observation but don't agree with the "crutch" comment, it is a tool to make you more proficient. If you have a line that you know is one MOA at any given distance, it is simply giving you a measurement for your hold over instead of guessing what 12" looks like at any given distance. With this method you still have to know and understand your ballistics @@jeffhays1968
@@OutdoorSolutions You see, after several decades, I don't GUESS what 12 inches, or 18 inches or 6 inches looks like. I know precisely what they look like. I feel at or under 300 yards technological "help" ( I'll not use the other word ) is A not needed and B lazy. AND as you stated easy to screw up a shot with. I'm sticking with that.
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?
No would not have anything to do with SFP of FFP

@@RosalindHarlan-r1h Ms Jackson
Try taking the pictures with the gun steady
We should have thought of that. Thanks for watching.
when hunting with SFP why all this talk about subtentions, just use your turret with any zoom!!!!!!!
When hunting you don’t always have time to dial or you don’t want to come out of your optic to risk losing sight of the animal n
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 ?
Good point. Zeroed at 100 yards. Cross hairs at zero are not effected by magnification, just your sub tension’s
@@OutdoorSolutions cool , thanks for the response !
It makes no sense that they make a scope like this
Really? What doesn’t make sense?
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
Did you read the title? We have other videos on how to zero. This video offered multiple field use tips.
This is not about zeroing... Lol
This is the most confusing comment ever. It mentions the expectations that nobody anywhere promised.
@dddur13 well you would think naturally a good field tip would be how to zero the optic and how to use the zoom and understanding the functions and it doesn't exactly make it clear
@@dddur13he talks about subtensions and what they mean but not how to utilize them when zooming in and out
