      There are a multitude of reasons to have a mil reticle and MOA dials.MOA dials support a more accurate initial zero, as well as wind favors using the simple in head MOA wind constant math. The wind favor solution can be directly applied to windage dial or be converted to inches and applied to mil reticle from range card notice of inch favor need at distance in mils. The mil reticle is preferable to an MOA scaled Reticle since the range finding formula for mils is less math than the MOS formula, just known target size in yards times 1000 divided by target size in mils equals target distance in yards.

    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.

    • @charlesludwig9173
      @charlesludwig9173 2 роки тому +1

      You should have just heldover/favored from reticle and not made any adjustment to dials. The dials in your case would just be used to get an ideal no-wind ZERO. That's what makes mil reticle and MOA dials mix so awesome. No conversions ever necessary when you have a range card synced to the mil scaled reticle.

    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.

      @charlesludwig9173 2 роки тому

      A mil scaled reticle and MOA windage/elevation control yields speed and precision to aim, which is not possible with a mil/mil, MOA/MOA or MOA/mil combination. Trial of systems makes it clear.

  • @charlesludwig9173
    @charlesludwig9173 2 роки тому +2

    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.

    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.

      Correct, so in a simple words investing thousands in a scope for a range shooting to 800 yards is just waisting your money. I know this as a former artillery man. Investing in an average tactical scope shown in the video is more painless to your pocket, only if you know how to use it. Corrections on a usual range out there are overkill cause once done, it cost a money(bullets) to do reset again to a usual 100 yards targets.I like my "budget" Howa 1500 it makes other guys mad when they see what good shooter with average scope can do. Corrections are done trough mil dots on scope and not trough knobs which are set on default.👍

    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).

    • @The_Touring_Jedi

      To be honest 1/10mrad is quite fine adjustment and it is all about the shooter not the gun. You can have the best scope out there and the guy next to you with 200$ scope can still beat you.I have seen people expression as I was blowing tight groups at 250 yards with "budget scope and rifle" as they say and guys going mad with 3-5 thousands bucks eqiupment.My adjustment against any 1/10 Mrad scope is my breathing technic and concetration. As I said it's more about the shooter then the scopes.

  • @whomagoose6897

    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.

    MRAD basically is metric… call it 1 to 1000 relationship if you wish but it certainly is way more metric than imperial.
    Mixing MRAD with imperial measurements like you did won’t do you any favours. It will only worsen the fractals you have to deal with.
    Once you start using MRAD in combination with metric measurements the advantages become clear. Much easier calculate things on the fly dealing with metric.
    MRAD and MOA might do the same but they certainly aren’t the same.

    • @Logan_roberts7
      @Logan_roberts7 2 роки тому

      Yes you can with moa as long as you know the relative size in inches of your target. Waist to head is around 36".
      36"÷MOA found in reticle × 95.5 = yards
      If using FFP scope magnification doesn't matter, but using SFP you will have to be on max magnification for this to work. Would be useful if your laser range finder doesn't work in the rain or fog.

    • @JohnDoe-zl6qw
      @JohnDoe-zl6qw Рік тому

      Yes. If you want to use yards as your measurement, the formula is:
      (95.5 x height of the target in inches) / height of the target measured in MOA using the scope's reticle
      Example:
      Prairie Dog standing on its hind legs is about 10 inches tall. You view it through your scope and see that it measures 5 MOA using your reticle's hash marks. To find the range to that Prairie Dog:
      (95.5 x 10 inches) / 5 = 191 yards
      Caveat: if using a First Focal Plane scope, this works at all magnifications. If a Second Focal Plane scope, there is only one magnification at which the reticle will accurately measure a target (the manufacturer will tell you what this is in the manual included with the scope). When using the SFP scope, you must dial to that magnification before attempting to use the reticle to measure a target.

      Actually, it refers to a milli-radian being exactly 1/1000 of a radian, so that if your 6 inch target covers 1 mil in your scope, the range is 6,000 inches, or 500 feet. Because 1 km is also 1000 metres, it also works as you've described, but it works with ANY measurement unit, provided you use the same unit for both target and range.

    • @JohnDoe-zl6qw
      @JohnDoe-zl6qw Рік тому

      Only if you use the common shortcut of rounding MOA to 1-inch-per-100-yards. If you use the true measure of 1.047 per 100 yards, then your math will be precise. At the distances most people shoot where it matters in terms of life-and-death (self-defense) or survival (hunting / food), that 0.047 difference is no difference at all.
      At 500 yards (about the furthest most hunters would ever take an _ethical_ shot), it's a difference of ~1/4 inch. In other words, negligible. For self-defense scenarios at distances of 7 to 15 yards, it's essentially non-existent.
      It might become an issue for benchrest target shooters. But unless that's your game, I wouldn't worry too much about it.

  • @karlfriedrich7758
    @karlfriedrich7758 2 роки тому +1

    At the end, he said MRAD has nothing to do with metric. That's not true, Mrad is a (SI) unit and is used directly with the metric system. There's not much point using a Milliradian scope and ranging with yards and calculating drop in inches because yes, then it still seems imprecise.
    However, if you use metric for those measurements you see that 1 mil adjustment is 1cm at 100 metres. 2cm at 200m, 3cm at 300m and and so on. That's really easy and precise to quickly figure out holdover or clicks.
    If you know your bullet drops 10cm at 200 metres, you'd simply dial in 0.5 mil adjustment (5 clicks of 0.1mil) to get zero, since 1 MRad would be 20cm to at 200m you simply halve it.
    Easiest way to do it in the field to calculate your exact mil adjustment with complicated distances and ranges (if you already know your bullet drop at ranges), is drop the last digit from the range in metres and divide your drop in centimetres by that distance. E.g 950cm drop at 900m becomes 950cm ÷ 90 which is 10.5, therefore 10.5 mils of adjustment are needed (105 clicks at 0.1mrad a click).
    458 cm of drop at 700 metres? 458 ÷ 70 = 6.54 mils adjustment (65 clicks)
    1341 cm drop at 1000m? 1341 ÷ 1000 = 13.4 mrad (134 clicks)
    So on and so forth, with whatever distances you want, that formula holds true as long as you use centimeters for drop and metres for range.
    Of course if you don't have a dope sheet and are just going off previous hits, you just dial in the appropriate mils of drop and drift.

      it also works flawlessly in imperial, but only when you stay in the exact same measurement unit

      the big plus of metric is that just like Mil it also is base 10, so doing conversions using these 2 systems is alot faster than anything else
      with MOA you still need to know the rough conversions between all the units, and know that at larger ranges you get a error that isnt there with mil.

Inches has absolutely nothing to do with anything in the course of a solution.
      If your busy sweating how many inches are in a Mil or MOA at a given range....your bench racing for the sake of bench racing. Your path to a solution does not require that math at all.
      The further shove the point home....the system works without even knowing how far away the target is. Pretty hard to backtrack that stupid math when you dont even know the distance it is away.

    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.

    if it has a 1 to 1000 relationship then it has every bit to do with metric. The metric system is very uniform in that all numbers are divisible by 10 or are a multiple of 10. While using inches, feet, and yards is insanely arbitrary. What he also neglected to mention is that while at 100yards .1mil adjustment is .36in. at 100meters .1mil is .9998 centimeters. Which is far closer to an exact measure than the arbitrary MOA. 1mil then at 100 meters is 10cm. So you get 10cm (10 clicks) of adjustability. Versus 1MOA at 100 yards being 1in (4clicks) of adjustability. Communication of MOA adjustments is more difficult as well if you work as a team, a lot of the time it requires multiple turret rotations, and larger numbers to communicate and remember. Like a 29.3moa adjustment, while a similar adjustment would only be 8.5 on a mil scope. I wouldn't even have done 2 rotations on my mil scope, and the number is far easier to remember and communicate. This is why in the military we use mil's.

    • @taylorharris5601
      @taylorharris5601 4 роки тому

      @Log Splitta to put it in another perspective for you it works like this: with MRAD when you make a shot and you miss and need to make an adjustment that adjustment is always divisible or multiplied by 10 in some way shape or form. Like you need to go up 36cm at 100meters? Ok each click is .1mil so 10 clicks is 1 mil so go up 36 clicks or 3.6mil. Easy. See multiply and divide by 10.
      While MOA is weird. Need to go up 36 inches? Well each click is only 1/4 of an inch so 4 clicks is 1 MOA. So now 4 x 36 = 144 clicks or 36 MOA.
      With MRAD you are working with 1's and 10's and 100's. Easy math numbers. With MOA you are working with weird numbers especially as you go out to distance. Mil clicks progress with range uniformly. MOA progresses uniformly, but the click values of MOA do not.

      Your first post implied you get more "clicks" or adjustment with MRAD when you said that you get 10 clicks at 100 meters vs only 4 "clicks" at 100 yards with MOA. However, the difference in 100 meters vs 100 yards is significant so that's comparing apples to oranges. You only get 3 mrad clicks at 100yards or about 14 MOA clicks at 100 meters.
      It only makes sense to measure distance in the units your scope is measuring adjustment. More clicks per distance with MOA because it is more fine.
      MOA clicks also stay consistent with MOA at range. It will always equal 1/4 MOA (or maybe 1/8 if your scope is set for such). Same as mils are always .1 mil adjustments; the values just multiply with distance for how much that "click" graduates to by the time it gets to target.

      @@skys-the-limit the difference between 100 meters and 100 yards is only 9 yards. And yes i know all of that, but the point is the math is far more difficult. No matter what you say there is a reason militaries all over the world use MRAD. MOA works perfectly fine if you are ok with crazy turret rotations at longer distances, longer numbers to work with, and longer communication times.
      The fact of the matter is MRAD is far more simplistic, mathematically, than the arbitrary imperial system of measurement. And, no MOA does not stay consistent from 100 to 200 to 300 yards and so on. That is a common misconception.

    I need to see prices. I have a Savage MSR 15, and it is every bit as good as my Sig.

      I've heard the Savage rifles are really good, thanks for sharing your experience with yours. Thinking about getting one myself.

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

    Thank you, good presentation. 6283.4 kind of looks like 1000 x 2 x Pi, to me. Hmmm.

    Shouldn't it be 6283,2? (2*pi)*1000?
