You did a great job explaining it. I’ve spent hours reading and watching other ppl try to explain this but yours is hands down the best imo.
Best MOA/Click conversion vid I've ever seen. No BS, straight to the point. No talking just to hear your head rattle. Very useful info. Thank you.
I’m watching this 7 years later and it is still the best video
Yes, I did miss speak (had to re-watch the video). At 400 yards, with a drop of 25.7 inches, convert to MOA by dividing by 4.0 inches per MOA (not going exact today), is 6.425 minutes worth of drop. With 4 clicks per minute, we get (6.425 min of drop) x (4 click per minute) = 25.7 clicks, which is rounded to 26 clicks of drop at 400 yards. Close to the 25 clicks in the video.
Nice to know someone is watching/listening ;)
I just watched this video for the first time today and as I new hunter is well explained and it made total sense. I do need to ask you though, anything .5 clicks gets round up? What If it’s .3, does it get rounded down?
Finally! An explanation that takes you all the way through the process. Now I understand. Thanks
The best one that I've watched so far. Showing your chart was what made it all make sense. Thank you
Just starting long range shooting and I can't tell you how valuable your video is Great job on an excellent presentation
Finally. Someone that can explain things where I can understand. Great Job!! Great video!!
Man this is a thorough video, even explained that MOA isn't exactly 1 inch which I didn't know and is definitely helpful in being as accurate as possible at longer distances. Diagram was cool too for people who needed it to understand sighting in and drop 👍 great video
Thanks for a great video. I used your video to confirm my thoughts about using MOA for long range shooting.
Best explanation on YT. Greetings.
Great video, really useful information. Thank you for keeping it simple for us mere mortals. I learned something that I had never even considered. Thank you
Very informative video spelled out in the clearest way I’ve seen yet. Nice job
After reviewing this excellent lesson I attempted to take your chart and prepare it using MIL instead of MOA. I think I did all the conversion including bullet drop from inches to centimeters. I was hoping you would consider presenting this video in MIL to see if I did that correctly. Thanks for this great video.
Very clear explanation... I really appreciate you explaining and illustrating the point
Brilliant video. takes something a bit frightening and made it really easy to understand. Just what I have been waiting for, Cheers.
Just quick thanks for the educational video, watched it twice got my chart down to the desert and it worked.
Thanks, glad you liked the video.
Thank You! Best description yet!
Great presentation! I'm in process of buying my first rifle for target shooting and maybe one day hunting. You did an excellent job with the both graphics and tutorial.
Great vid man! Cleared up all of my questions
Thank u so much im hunting coyotes long distance at a farm.up in ontario and am new to long distance shooting using 22 250 you have xplained it well i will put this into practice on my vortex viper and see how it wors for me this winter
Great video brother! Thank you! I get it now! I been stressing about learning this and I have it.
Thanks for another great show. Godspeed and stay safe.
Excellent video............makes it easier to understand.
Thank you sir you explain it very clearly and in a easy method no one can explain like this
Thanks. I'm glad you liked it.
Amazing video. Thank you
Great presentation. Thank you sir.
Thanks for Video...Learning is easy with a good teacher..Thank you again
THANK YOUUUUUUU!!!! getting a 300 win mag and using it for elk but i used to use a 7mm rem mag and never used a rangefinder and just aimed high or low, id rather do this lol
I don't have nay ballistics calc at present. I typically use the tables in the back of the Speer or Nosler reloading manuals (the two that I have). The good folks at Leupold use the RCBS ballistics program.
I guess that there are several apps for mobile/tablet devices. So far I have been to cheap to get any. If you find one you like please post the name.
good presentation.
Clean and simple !
Thanks, nice job. You might mention the math correction in the video description. It threw me off a bit but all I had to do was watch that part over. Nicely done.
Are you talking about a "ballistic drop reticle" (goes by a number of names)? Yes, those reticles are made to give you the appropriate hold over for certain loads. Yes, the hash marks (or dots) under the horizontal cross hair work, when the scope is at the correct power and shooting a load that works for the reticle. It is very fast and reasonably accurate. If you are trying to be very accurate and/or shooting beyond 400 yards, then typcially you adjust the scope.
Great video.
By the time you count those clicks it's will be summer again. That's why MOA VS CLICKS IS faster, easier, and less erroneous
I think it would be faster to count moa instead of clicks being the scope already has them marked if you wanted to go up 3 inches at 200 yards 1.2 moa.even if you needed to dial over 12 minutes could be 1-1.2
Thank you!
Great vid!
Good video, thanks
Thax men this explains a lot
is it possible to use d=vt, assuming we know muzzle velocity and distance to target, find t, and plug into and y = 1/2 gt^2 to solve these problems? or is that just theoretical?
As far as drop...
To do the math you ballistics. Commercial ammo has this on the box or online. If you know velocity & ballistic coefficient then a printed reloading manual or a ballistics program will give you the data.
You can test the load at different ranges, if you can find a place to do this. This is best.
For hunting, and lacking any of that, just sight in about 1.5" high @ 100 yards. That will put you on target to ~300 yards. If the shot is "long", then aim a little high. ;)
how you get the number for the bullet dorp in inch? did you have any formula for the calculation?
damn, thank you! i finally understand!
He said if you have time to do it. If you watch long distance competition you will see they all adjust their scopes they don't just hold over.
If anyone’s reading this i downloaded the hornady app and you can create your own chart where you can change the variables and anything else you’d like
Yes, good video, still, beginning with the fact that scopes and sights move in MOA first the shooter must understand what's an MOA: MOA means minute of angle, an angular unit of measurement. This unit of measurement, which is equal to approximately 1 inch per hundred yards, is used to describe the distance in inches a sight adjustment will make at target distance. For example, a 1 MOA sight adjustment would move bullet impact 1 inch at one hundred yards, 2 inches at two hundred yards, 3 inches at three hundred yards, and 10 inches all the way out to one thousand yards.
Understanding the effect of sight movement in MOA is important to correctly adjust sights for bullets to hit where aimed; yet, the arithmetic for an understanding is easy. Using the simple math as shown, you can determine up/down sight adjustment needed; and, doing the math again, you can determine left/right sight adjustment needed.
1. First, think what the value of 1 MOA is at target distance:
Distance to Target in Meters / 100 = Value of 1 MOA in Inches at Target Distance
2. Next, think how many of those MOAS will fit into inches of needed movement: Inches of Movement Needed / Value of 1 MOA in Inches at Target Distance = MOA Adjustment
3. Finally, determine how many clicks to sight for needed movement: MOA Adjustment / Sight MOA Click Value = Clicks to Sight for Needed Movement
For example, let’s say you’ve set your target out to 25 meters and you’ve produced a group which is 2 inches low and 2 inches right of the target’s center. Remembering the M16-A4’s front sight has a 1 .25 MOA click value, and the rear sight windage drum has a .50 MOA click value you can now determine sight adjustment needed:
First, determine adjustment needed to front sight controlling up/down movement:
1. 25 Meters / 100 = .25 Inches
2. 2 Inches / .25 = 8 MOA
3. 8 MOA / 1.25 = 6.4 clicks (round to 6 clicks) to sight elevation knob in clock-wise direction for needed vertical movement of grouping on target
Now, repeat steps to determine adjustment needed to rear sight drum controlling left/right movement:
1. 25 Meters / 100 = .25 Inches
2. 2 Inches / .25 = 8 MOA
8 MOA / .50 =16 clicks to sight windage knob in left direction for needed horizontal movement of grouping on target
Yes
MOA is a geometry thing. For all practical purposes 1 MOA is 1 inch at 100 yards, 2 inches at 200 yards, etc. If you were shooting 1 MOA groups at 200 yards, the group size would be 2 inches. 200 yards is more challenging that 100 yrd b/c of wind, etc. When you shoot the bullet is rises a little (the gun is pointed slightly up compared to the line of sight) and then falls. A 200 yard zero means the bullet falls to the line of sight at 200 yards. Probably more info than you needed...
i got a question. if lets say i have a 2 inch drop. do i need to turn my turret to where it says up or do i need to turn it down, same for the windage turret?
Up
So if you zeroed your rifle at 200 yards you’d just do 9 clicks up as opposed to the 15 clicks if you were zeroed at 100, to get your zero at 300 and so on?
so the cal is drop in inches /( distance in meter/100)= # of moa to adjust.
Thanks
That's a real hard hoppy
Well on 200 Yards you will have 76.2 mm of drop, what you have to do is multiply drop of the bullet in inches by 25.4. 1 inch is 25.4 mm.
I am missing something what am I to divide to get the number of clicks
Great
Why do u to divide of bullet drops 3” amd 200 with a 1/4 click wouldnt all u have to do is make 12clicks up
Hi, great vid thanks. Quick question. I zero my rifle at 200 yards. Does this mean it would be 200 yrds = 1 moa, 300 = 2, 400 = 3 etc. Or would the measurement stay the same ie: 200 yrds = 2, 300 yrds = 3, 400 = 4 etc. Thanks for your help!
Yes 200 yards zero =200yrd 1moa,300yrd 2moa
6 divided by 4 isn't 24 so I'm lost. Multiplying 6 and 4 yes
I had to replay that part twice. The first time I thought I were hearing things.
Thnk
I don't have any problems shooting tight groups but I do have a dyslexia problem when it comes to math and how that math is interpreted on my scope. The thing that throws me off is that in my mind when I crank my turrets "UP" it registers in my brain as moving the cross hairs up; which would bring your point of aim down.
The point of dialing a "Come-Up" is to bring up your point of aim for longer ranges so, I'm assuming that the turrets on scopes are reverse threaded so as to move the cross hairs downward in order to bring the point of aim upward. Is this correct? I know it sounds stupid but that's where my mind is at with regard to using scopes.
Like I stated above. I have no problem shooting tight groups. I'm like a good guitar player who can't read music. With enough practice I can memorize points of aim out to distance but it sure would be easier if I could figure out how to just dial in my points of aim rather than having to memorize them.
I think of up as moving the holes in the target up higher. If you use the Leupold CDS scope, you can get a replacement turret cap that has yards to target instead of MOA numbers.
Or... find velocity of the round. Then use a rangefinder to determine the distance the round will travel. Neglecting air resistance, put the numbers into the equation distance = bullet velocity * time + .5 * acceleration * time ^ 2. The time can be determined using the same equation but using 9.8 m/s^2 as the acceleration and using the y dimension for the velocity and distance vectors.
“Neglecting air resistance”. Really... The bullet velocity is best described by a differential equation. It is not a constant, which is assumed by the equation you listed. “Why does the bullet velocity change after it exits the barrel?” Good question. Air resistance.
Matthew Yee . . . in a vacuum . . . not practical!
Instead of dialing in with clicks on a changing target can you just hold the scope reticle up by the number of MOA that your scope is calibrated for. So lets say mine is 1 MOA lines and sighted in for 100 yards. Can I just go down one "dot" and use that as a hold over assuming my target is 200 yards away? thanks
Not all scopes have a mil dot reticle, this information would be vital if you have a scope that doesn't have one
good
4:10 he says 6÷4 is 24 or he ment to say 6×4 is 24 please tell me he said this or meant to say this
it would help if there was another one of these for mils using metric instead of converting to yards all the time
Hi James it’s because 99% of shooting info on the web is all American😂 Why they need to take a simple 10 count (metric?) and then convert it to imperial yards and inches beats me! You would think as the greatest free world military use Mils and meters their civilian counterparts would fall in line!! Stay safe out there and enjoy your shooting. Regards Clive
but what about ballistic cofficent? it changes at different ranges, how do you account for that? do you take the ending bc? or just an average..
Garret Chambers ballistic coefficient relates to the projectile not distance
Morgan B actually ballistic coefficient does change through the bullets flight. For hunting purposes most just use the simple BC given for a bullet. However the ballistic coefficient changes as speed changes too. Also as the bullet flies through the air, the tip can be deformed by the friction of the air. Imagine the tip of a polymer tipped bullet "melting" as it flies due to air friction. Recently Hornady has come out with their ELD bullet which has a heat shield tip so it experiences less deformation while in flight. Check out this link www.hornady.com/bullets/eld-x#!/
Just as a theoretical question... is it true that a bullet dropped; and a bullet fired at the exact same time would hit the ground at the same time? Assuming of course the gun is aimed perfectly horizontally on level terrain and such. It seems elementary, but I began to wonder if the round produces any lift as it speeds through the air, like the wings of an airplane or glider essentially, although very minuscule. Or is that why really long distance shots are fired from an elevated position...?
true for a level barrel. the bullet flight is two components: horizontal, caused by the cartridge, and vertical, gravity pulling down. a dropped bullet has the same vertical component and zero horizontal.
Check out mythbusters. They proved this same question of yours
It is not that hard to figure for a set up in inches. Since 180/3.1415926 = a radian at one radian distance a drop or rise of one inch is = to 5 MOA. At 5x radian distances (about 57.29 ft x5) one inch will equal 1 MOA.
It’s a useful video, but not what I’m looking for, I’m trying to find the formula for calculating how far my bullets are dropping at each distance. Basic formula not including atmosphere because I’m just shooting no more than 600 yards
Gravity is an amazing thing.
At a velocity of 3000 feet per second (or 1000 yards per second), a bullet will travel 500 yards in 1/2 second and drop 48 inches.
If you hold a bullet in your fingers and simply drop it, in 1/2 second the bullet will also drop 48 inches.
Gravity is the same whether a bullet is shot from a rifle or dropped to the ground.
You forgot wind resistance and loss of horizontal velocity.
@@bgallaher77
You're right. With wind resistance and the loss of velocity the bullet will travel approx 410 yards in 1/2 second.
What is yard what is inch?
So, if you needed to ‘come up’ 25 clicks you could just hold on 25 looking through the scope to achieve the same results? @bgallaher77
Well, if you have a 6 MOA drop at whatever yard, and a scope with MOA markings with 4 clicks per MOA (6x4=24), and if your scope and rifle combination are compatible, then yes, hold over 6MOA.
How can I get drop inches? What is the method? And how can I get drop moa?
Get inches from a ballistics table or a ballistics calculator. MOA is approximated a 1 inch at 100 yards, 2 inch at 200 yards, etc. divid drop by size of MOA in inches to get MOA.
@@bgallaher77 Thanks dear.👍
Can you make a video on how to calculate the trajectory of the bullet?
I need how can I get height of the shooter(b). 🤗
Good video but you should go back and correct the audio on the calculations where you go from, Drop MOA to Clicks. You mentioned in your comments below the following;

Yes, I did miss speak (had to re-watch the video). At 400 yards, with a drop of 25.7 inches, convert to MOA by dividing by 4.0 inches per MOA (not going exact today), is 6.425 minutes worth of drop. With 4 clicks per minute, we get (6.425 min of drop) x (4 click per minute) = 25.7 clicks, which is rounded to 26 clicks of drop at 400 yards. Close to the 25 clicks in the video.
I believe the moa at 300 yds is actually 3.141 not 3.142
gj
You also need bullet weight to do the calculation!
Nope
Nope. Just bc and velocity. Online calculators ask for weight because they have a bc database. But get a reloading manual with published, on paper, drop charts. Does not ask for weight. No weight required.
That's funny, I have just been using an on line ballistic calculator to give me a bullet drop chart and it asked for the bullet weight.
Bullet weight alters trajectory shorly.
i.e. bullet drop!
Any change in weight will change ballistic coefficient.
Some one knows how to get the drop inch number of difrents ammo........
google 'ballistics chart federal 6.5 creedmore' or whatever cartridge you plan to use.
Ther are some terrified deer now. Lol
Correct me if I'm wrong but one click is a 1/4 at 100yrs, 1/2 at 200, 3/4 at 300 etc etc. If that is correct then the calculations in the video are off.
1" = 4 clicks !!...MOA =1" at 100 yards / 4 clicks / MOA=2" at 200yards / 8 clicks / MOA=3" at 300 yards / 12 clicks ETC>>>( actually 1 MOA = 1.047" ) . Then take your Bullet Drop at any distance and divide by MOA at that distance as stated above and this will = MOA needed to adjust ...Say it was 6 MOA ?? You would need 24 clicks UP ...LOL
What about the barrel length
Most companies list velocity from 24 inch barrel. Figure you loose around 25 fps for each inch that the barrel is shorter. That is a rule of thumb. It is worse with a magnum. A 20” barrel 7mm mag or 300 win mag is basically a 270 win or a 30-06. Most hunting rifles are 22” for regular cartridges and 24” or 26” for magnums.
For beginners please
26 inches at 400 meters. That is a LOT
MemoryLaneCinema 26clicks. Not inches. 26x.25=6.5inches
At minute 4:15 the math is wrong. The correct answer is 1.5 versus the stated "24". I know, I know. I'm an ass. 😁
I think never will understand that
WTH it was in face the whole time 🤔😣
I don’t understand moa whatsoever I just keep moving my scope till it hits the x ring much easier
1 moa is 1 inch at 100 yards, 2 inches at 200 yards, 3 inches at 300 yards etc. But most ammo manufacturers have a zero at 100 and give you adjustment in inches or adjustment in moa per yardage
Ya that still doesn’t make sense to me
"6÷4 is 24" your math ain't mathin up
I am Green to Rifle Scopes, I just bought a NX-* Nightforce. with a .05 MOA, is 1 click equal to 1" MOA? or is .05 just Equal to .05 I am going Zero at 36 yards.
everything you have done is a complete waist of time if you dont have a range finder or some way of ranging the distance of your target
Not if you're shooting at a range with the yards measured out for you...
I agree, for laser accurate (no pun intended) aquisition a range finder is essential. Besides, It's only going to set you back 100$
The hash marks on the reticle can also be used to find the range IF you know the size of the target.
So buy a chuffing range finder tight arse
@@denniskinkade5901 if you can figure that distance, you wouldn't be watching this video.
You're shooting deer at 400 yards? Are they stapled to a backstop on the range? Ok.
This video is for the guys wanting to punch paper at 600+ yards. Here is the hunting one.

go bloody metric
Quadrant14 no... metric is wrong
IKR. Used to shoot a .308 till I discovered 7.62 NATO. Life is much better now.
Hell No!!
6 divided 4 is 24? Where did you go to school
how you get the number for the bullet dorp in inch? did you have any formula for the calculation?
look up ballistic calculator and put your info in
i am not talking about the app , i am looking forsomething on paper calculation, thanks
the cartridge box has those drops, or you can google for a chart from your cartridge maker.
