Calculating a precise firing solution at extreme long ranges can be very difficult. Rex's 3rd generation version of these ballistic calculation forms are designed to be much more intuitive and much more user friendly than other systems that employ the use of poorly understood and difficult to perceive ballistic constants.
In this video, Rex will walk you through the how to use your CALC FORM to adjust your fire for the following ballistic effects:
1. Bullet drop
2. Barometric Pressure
3. Muzzle Velocity Variation
4. Ambient Air Temperature
5. Vertical Coriolis Effect
6. Humidity
7. Wind Drift
8. Spin Drift
9. Horizontal Coriolis Drift
10. Moving Target / Lead

Once you have the docs, be sure to save a master copy. There are a number of tabs on the bottom. These tabs include several CALC FORM configurations based on your optical sight configuration. Be sure to select the most appropriate forms for you scope set up. Also included are different PRIMARY FUNCTIONS and SECONDARY FUNCTIONS templates for different optical configurations. The last tab contains a Muzzle Velocity Variation Curve Generator which is very easy to use. If you have not yet confirmed you MVs at various ammunition temperature ranges, you can use this MVV Curve generator to get a ballpark idea of what MV trends you can expect at different ammo temperatures.
Please feel free to modify and customize these forms as needed for your applications.

33 hours of exceptional instruction. That's flipping sweet, Many thanks for all of the time, thought, planning, and excellent instruction that you, friends, and I'm sure family have put forth towards the 101 series to this point. I know that I have been watching the series for 14 months or so and I have learned so much over that time. I'm not a shabby rifleman to begin with, but this is taking me to another plane of existence when it comes to being a rifleman and I certainly appreciate it! I look forward to all future videos to continue my advanced marksmanship education.

I can't possibly express how thankful I am for this video series and how much effort has been put into it. I'm fairly new to the long range shooting sport but it's all coming together. I made a first round hit yesterday on a 10" steel plate at 700 yds. It was my first time shooting beyond 500yds so I was pretty happy. And it was no fluke. It was a calculated, confident shot using the knowledge I learned here to make it happen. :)

@ericmatthews3307 7 лет назад

Basic understanding of math is absolutely critical in figuring this out: especially order of operations. You must do powers first, then anything in parentheses, then multiplication or division and lastly addition and subtraction. In the correction for barometric pressure for instance, if you were to just type in 27.0-25.7x.75 you would come up with 7.725 instead of the correct .975. Math is critical, not just in this, but in life period.

Hello Rex, If you’re not an instructor, you may have missed your calling. It is obvious that you know this subject thru and thru and that you have a real passion for it. You have a real genius for paring a complex subject involving various disciplines of science and mechanics down into digestible chunks for dummies like me. We are grateful to you, your wife (for letting/helping you) and the rest of your compatriots for helping in this project. I am having a lot of fun learning and trying things that are new (to me). I find that I am shooting less and hitting more. This is something my wife appreciates. I spend more time playing with spreadsheets and less shooting/missing. My wife sees this a an economical use of my time. I don’t think she will see it the same as I evolve my optics :-D Looking Forward to Future Releases, Dan

@TiborasaurusRex 10 лет назад

Great to hear from you, sir! There are many more videos to come!

@tskfrcdgr 9 лет назад

Amazing, comprehensive set of videos. Truly goes to show that long range shooters are not the gun nuts portrayed in the media, but intelligent people with a competitive attitude. I fired lots of different guns and weapon systems in the army, but never anything long, long range. This series has been invaluable to me. Like having a free instructor while on a budget. Rex, how accurate are these charts out to. As in, do you need to go to the range quite a bit to verify your hits on paper match up your calculations? I've got a 6.5x284 norma hs precision I saved up for. I have been using the shooter app calculator on my android and have shot out to 600 and it's pretty much dead on. This seems more in depth, though. I'm always looking for an edge. Thanks for portraying gun owners and shooters in a positive, intelligent light.

@mikedunovan8751 8 лет назад

Great presentation, really appreciate all your time and effort. Noticed a bit strange thing though so i'll just drop a little suggestion. There's no such thing as a vertical Coriolis. Don't know why you call it that way. It's called Eotvos effect and it has nothing to do with target closing/receding to/from a shooter as indicated in the video. It's related to a centrifugal force adding or subtracting to gravitational force....long story really and not that it matters actually. Just wanted to give you a hint so you don't mix it with Coriolis. Those are two separated things altogether studied by different scientists. Best of luck and looking for more great videos from you! Your effort at teaching people LR shooting is unmatched by anyone.

@capitaltracker4694 10 лет назад

What an exceptional series of videos. Absolutely first class. Congratulations to all involved. I have 2 questions, the first relates to using the AHR actual horizontal range to calculate the superelevation drop taking into account the incline angle. Correct me if I am wrong but this is effectively using the Rifleman's rule. As we already have the drop in MOA, would it not be just as easy to factor this by cos(Incline angle) effectively using the improved rifleman's rule. Is this not more accurate. Secondly, should latitude not come into the calculations for both horizontal and vertical coriolis corrections.

@realAmpereD 10 лет назад

Thanks Lineman. I didn't even realize that!

@tyrone3006 9 лет назад

This is amazing that you give all of this info away. Thank you so much! I do have one question. You recommend MRAD but all of your charts and examples are in MOA and it seems all ballistics info is also in MOA. So to me it's doesn't seem like mils is standard other than reticles. Also, JBM calculates everything in MOA. I realize that we live in USA where we can't decide to use metric measurements or to not, so that might be part of it. So when I'm making my charts, does that mean I'll have to divide every value by 3.438, or maybe just the final indexed number on the turret?

Hi Rex, Around the 24 minute mark of the video I keep getting -2.465 not -2.755 for the MVV/Ammunition Temp correction. (2815-2900/10)*.29=-2.465. Did I do something wrong in the equation? Thanks for sharing all your knowledge!

@ryliefleckenstein1031 10 лет назад

when you're direction of fire is at 0 degree and a full value wind would be 90 degrees. Please correct me if I'm wrong, but wouldn't you want to use the sin of that angle instead of the cosine because the sin of 90 is 1 and the cosine of 90 is 0? I may not be quite understanding what you're explaining so if you can help that would be greatly appreciated. Also thanks for all of you're hard work it has all helped my tremendously!

@DanielFSmith 10 лет назад

Some noob questions... Why is the MVV factor derived from AHR? Wouldn't actual distance be more appropriate because it's related to wind resistance and time of flight. Also, firing at 30° down for 1500m might need an altitude correction in air pressure (is mean air pressure close enough?)

@davidsaunders55 10 лет назад

I agree, the target is about half a mile DOWN, roughly figuring .85" per thousand feet in altitude would be a gain of 2" of mercury with the mean/average 1" higher. Also the ambient air would be warmer by maybe 5 degrees or 2.5 degrees in the middle which might help in the other direction.

@brianmahler10 10 лет назад

Excellent video series. You have cleared up many confusing areas on this topic. Did I miss it or have you covered how to calculate the max height during the flight path of the projectile?

@downbubbledell850 10 лет назад

Wow! That made a lot of sense! Well done mate, got that across nicely again. Mad to think how just one small mistake on your inputs could make you miss by a country mile... Do you keep all of your old calc forms or ditch them once you're done?

@diverbob8 10 лет назад

Hi Rex, I've been wondering about where to find an education about ballistics for a long time. Thanks very much for your great work. I have owned the Ballistic: Advanced Edition app on my iPhone since it first came out but have not had the time to figure it out very far. I plan to go back and try to work my way through it to determine whether I can use it on the fly, so to speak. I wonder if you have evaluated it verses your method developed here? I contacted the app developer a few years ago to ask about how to gain an understanding of what the app would do and he just blew me off with a quick "It's in the literature".

@mhb1323 5 лет назад

Does spin drift and coriolis effect change much with respect to changing ambient temperatures and barometric pressures?

@jamesdaly5295 6 лет назад

The vertical wind adjustment does seem to be a big omission. I guess test and plot at range and then add section to calc form and Primary tables? Or is the effect not worth it? It has to be more significant than humidity. I dunno

@MrNiceKnife 5 лет назад

Hey bud, how is horizontal coriolis independent of direction of fire? Wouldn’t it matter if you were shooting N/S vs E/W?

@realAmpereD 10 лет назад

Is there any way you can email all these excel sheets with the BCs and ammo info and scope info? Aldo any calc form templates and such? I don't know where to start making these things and you have gobs of data already, it would be great. Is there a link maybe to download? Thanks for making all these! Really helps a brand new shooter like myself.

@TheRfmodulator 9 лет назад

So for corilois, does it matter which direction I was shooting when I zeroed the scope?

@jakwanda9407 9 лет назад

TheRfmodulator no sir it wouldn't, the horizontal coriolis will always be to the right in the northern hemisphere and the vertical isn't gonna be noticeable from 100 yard zero, unless you're zeroing your gun at 500+ yards you should be fine :)

@jeffgilkison6170 10 лет назад

what model newcon do you use? how does it perform, is there anything you don't like about it?

@ExON00 10 лет назад

Thats a Neat setup. Just one question, something that wasn't mentioned. If you have a strong tailwind, should you add it to your MVV?

@TiborasaurusRex 10 лет назад

Great question! Although a tailwind will translate to a decreased drag effect along your entire flight path and won't be directly subtracted from your MV. There is a lot to the calculation... but you can change the wind direction on JBM ballistics too see the end result of a headwind or a tailwind. If it merely changed your MV then you could use a MVV correction, but its a drag correction and should rather be plotted out independently using either software or observation. :-)

@countryboy16401 8 лет назад

If I wanted to see what the burn rate of a certain bullet, on jbm, before buying it how would I go about entering the muzzle Vel and temp at which said ammo would have been tested? Or do I have to actually shoot the round and figure out the Vel and temp for myself?

@npc0168 6 лет назад

if you take your load out and get two velocity averages with two temperature groups (preferably as far apart as you can in temperature) you can plot out a semi-accurate velocity curve. the more velocity averages and temperatures you have, the more accurate the plot. for instance, my current load shifts 22.5 feet per second per 10 degrees on average with a .5 percent deviation. to be able to do this, you have to actually shoot the rifle and gather velocity data. there really isn't a way to predict it other than reading on other peoples experience that have similar conditions. I know this is an old comment but I figured I would answer any damn way.

@jimmyforester8492 10 лет назад

what about elevation corrections for headwinds/tailwinds? I didn't see it at all on your calc form. In the case of the video, it had a tiny bit of tail wind, 75 degrees off of a direct tail wind, so the cosine of that is about 25.9%. Is that too negligible to correct for?

@abBEHSutube 7 лет назад

i have a TI-83 like what you have in the video, but was getting different answers when I multiplied by cosine. then I realized I was not in [Degree] mode I was in [Radian]. I wonder is that was an issue for anyone else

@davew2928 10 лет назад

How does rain figure into all of this? Would the pressure wave vaporize the drops ahead of the projectile and have no affect (assuming hypersonic) or would the added vapor distort the wave and move the bullet?

@TiborasaurusRex 10 лет назад

Rain has surprisingly less effect on a bullet than you would think. As a general rule, if you can still see the target through the rain, its not enough to cause a significant miss at that distance.

@nicholasjaikeran5041 7 лет назад

Problem 1 Muzzle Velocity Ammo Temperature Curve, the first spreadsheet , MeccaStreisand, and the Curve on Calcform spread sheet all calculate from different formulas. So which to choose from to walk out into the field with to have the best starting information. Yes I know I must log my ever changing MV I'm just wanting to walk out with the closest to reduce my headaches in the field. My other problem is twist rate. the numbers I get from Berger Bullets twist rate calculator, MeccaStreisand, and my own calculations using the Miller Twist rate formula all give different answers. Again what numbers to believe. Please someone help me determine what numbers to get behind. I'm a person that if the numbers don't add up scrap it all and I really want to get this.

Excellent scientific method. But introduces a big mistake mutiplicar the cosine by the distance to find the superelevation when to take the superelevation for the actual distance. multiplied by the cosine superelevation and that will be the new superelevation. the method used was used by hunters at distances up to 300 yardasd and is very bad for the calculation at a great distance.

@dopeofthepope 8 лет назад

I think nobody will ever understand what you just tried to say. What he showed in the video was absolutely correct. The actual horizontal distance is all that matters for the effects of gravity on the bullet.
