By far the most clear and concise way that I have ever heard this explained. Bravo.

Why does it seem like this guy would be a great math teacher

Little disappointed in this video. I was really getting interested with this guy and then all of a sudden... THE VIDEO IS OVER! This guy is great!

this old man looks serious - I gave him a thumb up after 5 secs.

Thank you for being a teacher, I'm trying to learn and you have shown me more in 5 minutes than I have learned in a hour with other people trying to explain the scope and math that I really suck at but you keep teaching there are many people like me that learn from people like you, thank you,

as soon as I saw the 1911, I smiled. I've ordered my very first 1911 and I am just waiting for it to arrive. Excellent video!

The absolutely best description of Mils and MOA, breaking it down to the reticle scale .

The simplest and most concise explanation of the difference between the two that I have seen. Great video!

Great... teacher. Never saw in six minutes such simplicity !!! Thank you.

Best and most concise explanation I've ever heard. Thanks

You as re freaking brilliant, thank you for being one of the 1st people to explain this correctly 👏

I've always used MOA. I got a MRAD on good deal and this guy just cleared up so much confusion for me.

I am new to shooting & scopes but highly impressed by the way you explained such complicated thing in very simple way, please make more videos like this, God bless you.

Last 20 seconds were worth the whole video - also excellent and very helpful video, thank you

For the first time in 30 videos, I get it! Well done Sir. Excellent presentation.

Cory Trapp is one of the premier long range shooting instructors in the US.

I'm a machinist with a PCP Airgun. Obsessed with accuracy shooting groups at over 100yds sub MOA. Regulated .25 cal Taipan veteran. LOVE THIS!

Thank you for the great infos. I’m trying to understand the difference between the two before making a purchase on my next scope. So I guess I will be sticking to MOA as I always do. Once again, thank you!

They are both good and both work, damn thats what I needed to hear, so basically use personal preference

And here I am competing for the past 2 years with a Leupold Mk 4 scope with a TMR (mil reticle) and 1/4 MOA turrets. At my last competition with .22lr, I had to shoot 3 targets between 180 to 282 meters from 3 different positions (range changes), which after some mind boggling math session turned out a setting of 20 MOA up on the turret and -3 to +6 mils holdovers on the reticle. Great fun.

Loved this video. Awesome explanation. Hit me in the heart.

Excellent and quick explanation. You sir earned another subscriber today

0.1 mrad = to 1 cm @ 100 meters and 1 mrad =10 cm @ 100 meters and so on . For example @ 500 meters 0.1 click is = 5 cm. its a piece of cake no need to get confused Very easy to calculate MOA is better to use with inch measurements

This is the clearest and easiest explanation I've heard. Thanks so much

Great video, and if you are a person with a short attention span, listening at 1.5 speed is wonderful!

the best video explaining the confusing world of MOA and MRAD

Great video. Thanks for posting this.

That was some useful info. Basic and precise, a good jumping off point. Thank you.

Awesome clarification. More please. Regards from the UK.

thank you for a very clear explanation.

Thank you for this, I’ll stay with MOA and make sure scopes purchased correspond.

Well they had these type of sights for decades on Biathlon rifles and they are super precise. Adding an adjustable peep is of course another advancement that a biathlete does not need since they always shoot 50meters. Peep and globe fronts are the most accurate way to go for iron sights. well done!

This is pure and simple. I like it.

Excellent explanation Sir - Thanks.

Very easy to understand, well done

I was carving this up, like everyone else semi mocking this video, until I realized that this is probably the best video for the true novice.

This is a discussion that negates any consideration for mathematical origin for radians, as the number of radians in a circle is actually that of 2 times Pi, as a radian is the angle that will give a length of circular arc equal to the radius, approximately 57.3 degrees. The MRAD system, whilst yes, being completely unrelated to the metric system, does allow for a simpler series of conversions thanks to its coincidental relation of 1/1000th measurement. It also just so happens that in the usage of the metric system with MRAD calculations with metric units you get a much more refined value of distance at target.

So, MOA is the American way. All I needed to hear.

best video i have seen yet

Awesome video. Really well explained. Could listen to this guy speaking all day whilst still not having a clue what the segments in MRAD represent. I'll stick to MOA I think. Much simpler

this video was the easiest to understand and made me feel like i was in a class room with him.

Great video. Thank you Sir.

love it works great. just the right size

Probably the clearest and best explanation of the two systems. The most important part is make sure that your reticle is the same as the turret adjustments. Either MOA for both or MRAD for both. Neither system is technically better. MOA is slightly more precise for zeroing the firearm, but neither will affect group size, just point of impact. Only the tacticool guys (keyboard commandos) will argue one is better than the other. Pick the reticle style that you like and go with that. An easy to use reticle that allows easy corrections for wind shift adjustments or holdovers is all that is really important.

Great instruction. 👏

Very nicely explained 👍

Extremely clear and easy to understand explanation. Thank you. Too bad I failed every math class I ever had to take. Great info

A very good teacher

A reasonable explanation, but you left out an important consideration. MOA scope reticles with MOA adjustment knobs are commonly IPHY (inch per hundred yards). Scope manufacturers do this to eliminate any rounding errors and make adjustments and use extremely simple, math free and easy for those of us who like feet and inches.

Thanks a bunch, you got my vote

Now I was getting into this video and it cut short, oh well, have a blessed day sir anyway.

this man is just awesome

Thank you so much. If anyone wants the tldw as long as the reticle and knobs match mil to mil or mrad to mrad it doesn't really matter. Just different calculations.

Excellent! Thank You!

Finally I understand moa best mathematical explanation

Great information thanks

Well presented Thank You

Good info. Thank you.

Excellent information!! Especially for a rookie like me🤓

If I could give this heat packing Santa two thumbs up I would 👍🏻👍🏻

Good points adressed here. How a scope comes out of a factory with a mil-reticle and moa-turrets boggles me. I’d like to add that using mrads comes into its own when you start using meters rather than yards.

Love the background music.

Great video

This guy is a legend...and no idea who he is.

What are MRAD's and MOA's and why am i just hearing about them now, Jesus guides my bullets.

Great Presentaion👍🏻 Question, why or who would produce an optic that the retical wasn't married to the turret?

I use the metric system and have a hard time using yards feet and inches, hence the milrad being a x10 incremental scale makes more sense to me, great explanation, thanks.

Best explanation I have been given. I seen the video heck now I want to take the class. Andrew you're not that smart.

In life only a very small percentage of people should be teachers ; this guy is one !

Badass channel.

That’s pretty good stuff

Good video, Im trying to figure out ---what is the moa at 8x, 10x, 12x, 15x, etc, etc, zoom at 100 yards given that at 6x zoom it is 1.50 moa? Im trying to figure out what the best reticle is? The dot at 100 yards at 6x is 1.50 moa.... This is a Second Focal Plane. Is there a formula? Thanks....

To do a quick conversation from M-rads to MOA's just multiply the M-rads by 3.44 to get a close result. Say if your spotter says to move windage 1 Mil. 3.44 x 1 = 3.44 then round to the nearest MOA on your scope. My scope has ¼-MOA adjustments. 3.44 is close to 3.5. Move the turret to 3.5 and shoot. Here is proof of the 3.44 calculation factor. For yards: 3.6 ÷ 2.047 = 3.438395415, round to 3.44. For meters: 10 ÷ 2.91 = 3.436426116, round to 3.44. Whichever distance measurement you choose, yards or meters, use 3.44 to convert. For those accuracy fanatics the difference between Mils or MOA's is less than the diameter of the bullet. Here's the proof of concept. Three clicks of a Mil based turret using yards for the measurement is 1.17" and one MOA is 1.047". 1.17 - 1.047 = 0.123. Less than the diameter of a .30 caliber bullet. Now for meters. Three clicks on a Mil turret is 3-cm. One MOA in 100 meters is 2.91-cm. Doing the math, 3-cm - 2.91-cm = 0.09-cm. Once again less than the diameter of a bullet. Been using a mixed system for years. The US Army did it this way for decades. I will say that a first focal plane scope has certain advantages over a second focal plane scope. But, not in all accounts.

I’m learning good video

I take it this whole course isn't freely available on KZfaq is it?

Thank you lot sir

Got a old weaver scope on a game after 308 horizontal a thin line vertical thick line just ends after it crosses the horizontal line should I target at the tip of this line like iron sites?

MOA =course adjustment, MRAD=fine adjustment. Got it. Best explanation yet.

❤ Дуже круто, дякую!

thank you

I think I still need to go to academy for this

Well said

Thumbs up solely on the beard and OG factor!

Very simple and easy to understand way of looking at it all! LOL I have never used a scope in my life and always just used irons! To this point i have never missed a target out to 400yards roughly!I'm talking about a 10 12 inch circle target and have never missed one completely after the 1st few shots from any rifle! But i am planning to buy a scope as things are getting thick and i want ot rid myself of targets befor they ever get close!

Was this filmed on an iPhone? As the audio is audio

Good class

I feel like this guy should be teaching shooting class somewhere. Sign me up

I find it baffling that manufacturers would produce an MOA reticle scope with MRAD knobs or vice versa. Is there any reason for this at all?

excellent

0.1 mil variation on your mil scope knob correspond to a 1cm drift @100m. milliradian system is on pair with the metric system.

Thanks.

For best results do mix mil scaled reticle with MOA windage and elevation control, whereby the reticle is used for range estimation and then used for a hold made known by range card. Use MOA windage and elevation controls to establish initial no wind ZERO and adjust windage as needed to counter wind from MOA Wind Constant formula. A mil reticle hold for wind can be made just discerning wind counter need in mils from a range card. The bottom line is no conversions from mils to MOA or MOA to mils is ever necessary. Here's everything anyone needs to know: MOA (minute of angle) and mil (mil-radian) are angular units of measurement. A MOA equals 1.047 inches per 100 yards, while a mil equals 3.6 inches per 100 yards. Sights and scopes move in MOA or mils and scopes may have a reticle scaled in mils or MOA, which is a means to estimate distance to target and use the reticle for a bullet drop compensation function. Common to all functions, the amount of MOA or mil adjustment made to the sight describes the distance in inches a sight adjustment will make at target distance. For example, a 1 MOA sight adjustment would move bullet impact approximately 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. Mathematical formulas must be engaged to find the amount of MOA or mil movement needed for bullets to go in direction where aimed; yet the math is easy. Here’s the simple in head math MOA formula to determine up/down sight adjustment needed; and, doing the math again, 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, figure out how many clicks to sight for needed movement: MOA Adjustment / Sight MOA Click Value = Clicks to Sight for Needed Movement So, let’s say you have set your target out to 100 yards, and you have produced a group which is 2 inches low and 3 inches right of the target’s center. In this scenario your scope’s windage and elevation adjustment controls have a .25 MOA value per click. First, figure out adjustment needed to sight control up/down movement: 1. 100 yards / 100 = 1 Inch 2. 2 Inches / 1 = 2 MOA 3. 2 MOA / .25 = 8 click turn of elevation control in up direction for needed vertical movement of grouping on target Now, repeat steps to figure out adjustment needed to rear sight drum controlling left/right movement: 1. 100 yards / 100 = 1 Inch 2. 3 Inches / 1 = 3 MOA 3. 3 MOA / .25 = 12 click turn of windage control in direction to move group left for needed horizontal movement of grouping on target Now, when Mils or MOA are scaled to a scope’s reticle, the reticle will have a bullet drop compensation function and can be used to discern target distance through range estimation formula. Here’s the MOA range estimation formula. Target Height in Inches X 95.5 / Target Height in MOA = Yards to Target Shooting at a target 44 inches in height appearing to be about 4.2 MOA the equation would look like this: 44 X 95.5 / 4.2 = 1000 Yards Now, here are the mil formulas: Target Height in Inches X 27.78 / Target Height in Mils = Yards to Target, or Target Height in Yards X 1000 / Target Height in Mils = Yards to Target Shooting at a target 36 inches in height appearing to be about 1 Mil the equation would look like this: 1 X 1000 / 1 = 1000 Yards Finally, the MOA Wind Constant formula is a means to understand sight adjustment or hold needed to counter wind. After the shooter has appraised wind value, for example, a 10-mph wind from a quartering direction would be said to have a 5-mph value, a simple formula will allow the shooter to adjust for the distance that the wind displaces the bullet, when the MOA constant for the cartridge/distance has been gleaned from a ballistics calculation. Distance to Target in Yards / 100 X Wind Value in MPH / Constant = Bullet Drift in MOA For Example, here’s the formula using the constant of 7 which is correct when shooting 5.56 M855 ammunition from an M16-A4 at 600 yards: 600 Yards / 100 X 5 MPH / 7 = 4 MOA Bullet Drift To get the drift in inches the shooter will take the distance to target in yards / 100 X Bullet Drift in MOA. Shooting at 600 yards, with wind appraised as having a 5-mph value, the formula would look like this: 600 Yards / 100 X 4 MOA = 24 Inches of Drift So, which mil or MOA formulas best support sight adjustment, range estimation, and wind counter speed and precision needs? Trial of both to discern the best balance of speed and exactness for all needs might suggest a mil scaled reticle for range estimation, while zeroing exactness and wind counter speed might suggest sight adjustment in MOA. In other words, pairing a mil reticle and MOA elevation/windage control.

You kinda said MRAD was preferred for distance between 300/1000 meters. .300 Weatherby mag effective range 1100 yds/meters. Which would be your choice for Long distance Elk?

I suck at math but stuff like this speaks to me

radians and MOA (or rather divisions of pi) are more of trigonometry thing. as a radian is standard divizion by the radius and radial circumference and a pi-angle is derived by the circumference and diameter. radians are often defined in terms of pi. use of mili-radians only relates to their base ten divisibility in simplifying calculations for more complex trajectories when used in compound with metric measurements such as with artillery which has an extreme arch and angled fire.

The series expansion for trig functions are expressed in, use measurements in radians for domain values. So if you're using a slide rule to figure out range you might want to go with radians.

if youre scope looking between two scopes with one adjusting in 1/4 MOA and the other in 1/10th MRAD, for precision shooting the MOA scope would technically be superior because your adjustment sizes are smaller, so you could potentially sight it in better (although your gun is probably too inaccurate for it to matter).

MRAD scale was designed with ranging in mind. That's why it's such a weird number for the angular divisions.

Decided to give my left ear a workout today

Great explanation. But why do you have a sidearm on for a class room lesson ?
