Elementary: Subtract the cosine of your weapon's angle of incline from the cosine of the bullet trajectory at zero incline and known distance, if negative, hold under; then shoot some twenty rounds, take note of the delta, use that information and forget about trigonometry.
Very nice Matt really informative i would like to see a video of your setup and how you use it to calculate all the stuff when out in the field. Good stuff man
Watch lots of your videos. But man. Iv got to use mathematics.. not for me.. I just put a target up a tree that was 20 yards up and I was 50 yards away and it was 1 to 1. 1/2 mil under. Want to see a video doing it that way would be great
Who on earth would read a book on inclination adjustment? 🙄🤔 You are too damn crazy about preciseness and theory. And ... that's the reason SO MANY people like and follow you. Just keep your crazyness going...❤️
Your knowledge of ecology and riflemanship is always impressive. It seems that the guys who really get the science better than anyone, are air gunners.
It is a lot like reading the wind with a .22 rifle to prep for using a 260 Remington. You learn a ton more due to the sensitivity of the bullet at 100 yards.
As these slugs have moved the air rifle sport on, shot on live quarry, should not come down to guess work.There is no substitute to trigger/range work. Stay safe 👍🇬🇧
Another way of explaining the discrepancy between the COS-rule (i.e.) horizontal distance determines hold-over or -under, is by stating that although the projectile only drops during the horizontally part of its trajectory; i.e. total distance x COS (gravity only works on that part of the trajectory), the projectile DOES actually travel the WHOLE distance!!! Ipso facto, the projectile is subject to air-resistance over the complete trajectory, not only the horizontal part... I was taught that the “Hunters-rule” is a mere “Rule-of-thumb,” which it naturally only is. At the extremes, say a vertical shot up or down, COS x distance to target would, theoretically, be zero. Anyone that has had the chance and privilege to hunt Chamois in the Swiss Alps probably knows this from dire experience. Near vertical shots down do present themselves during those hunts! Figuring out the POA when ZERO meters of gravity applies to a shot is extremely difficult... There is no “chance” for gravity to bend the bullet trajectory down from the initial upward trajectory.... To add insult to injury, in case of a vertical shot there is no more “upward” or “downward.” The bullet simply continues traveling in the “+” direction of the scope... A miss is almost always the result, albeit for the most experienced hunters.
@AirArmsHuntingSA: Glad I could help out a bit! By the way, I just missed you guys at Krale’s by a day or so. Would have been very honored to shake your hand... :-)
Matt, as usual, a very detailed lesson; compensation for shooting angle. I learned a lot. Please do an up to date video detailing your scope camera setup. Part numbers, specific models, lens, adapters, etc. Limited info seems cover the GoPro, but not the other, very worthy, lower cost cameras. Thx...
For sure! Not easy! What I do is I stay in one position and pre-calculate for different parts of the roof so that I can shoot right away when they land.
I pree culculate something like 50m 40°/45/50/55° etc before then I simple memorize in different distance I'm going to shoot we only shoot short range like 20-70max it's easy to memorize 😊
Another way to put it is that when you shoot upwards, the velocity of your projectile can be decomposed in horizontal and vertical initial velocities . The vertical velocity counters the effect of gravity and reduces the drop.
My answer to the long shots or the incline shots is the sig kello 2400 it has worked for airguns or center fire I have used it out to 1900 yards with the 338 lapua. And over 300 yards with airguns.
Good to know the ballistics calculator is correct. Here are some conventional and unconventional factors that may play a part: As a first order calculation of bullet drop, horizontal distance matters. For air resistance, actual flight path distance matters. This is greater when shooting up or down a slope. Also, when shooting up or down at a steep angle, the projectile speed will drop faster or slower due to the change in gravitational potential energy. These effects are magnified as you approach a significant percentage of the maximum range the projectile can travel. As the extent of the gravity related velocity decay adjustment is affected by an integral of projectile velocity over range, the latter effect needs to be taken into account for long range airguns - as they are generally subsonic at the muzzle. Not so much for centerfire rifles, when shooting at similar 100 to 150 meter distances; because their maximum range is so much further. The more loopy the trajectory, the more it is distorted by gravity. If you shoot vertically downwards, no drop compensation is required. If you shoot vertically upwards, drop compensation in the form a robust helmet is a must :). Better not try the the latter at all...
If you shoot at 90 degrees upwards, wouldn’t the projectile velocity when it hits ground be its terminal velocity? Assuming a lead pellet, that shouldn’t translate to many ft lbs I would imagine, but I may be wrong
Well said. With most center fire rifles at "normal" hunting distances, even at very steep angles, wind resistance effect on the calculation isn't necessary. If I were a sniper with a 338 Lapua engaging a target from 1800 yards and a 30º elevation, wind resistance over the distance of the flight path would have to be part of the calculus.
Matt! WOW!!! Thanks again for a great video! As a competitor in PRS & F-Class matches I have been aware of Bryan Litz and his SHEER GENIUS in the world of ballistics; in fact when I first learned of how "ballistic" the PCP airgun world had become, HE was the 1st person I though of contacting about his foray into this area. As also wondering when precision bullet manufacturers such as LAPUA, BERGER, SIERRA etc would also start producing more accurate slugs for PCPs. Just a simple question in regards to this video; at 5:09 you list your ballistic table for this particular gun and slug, did you do any downrange testing to confirm these numbers?? STRELOK PRO has a great tool in their software for correcting the actual POI vs its calculation as I am sure you are aware, but for those reading this comment, I can attest to BOTH STRELOK and APPLIED BALLISTICS programs as being EXCELLENT tools for shooters. Thanks again for these great videos, keep up the great work!
Well that was a complete head-mash and explains why I missed so many rabbits the other week, which were all on inclines. Also didn't help that it was also 20mph winds.
Gravity (9.8 m/s2) is impacted by time (not distance). At steep angles like 60 degrees the line of sight is markedly longer (double) than the horizontal distance, significantly affecting the trajectory because the TIME to target is twice as long, where gravity’s effect is exponential. I was hoping the video would explain this clearly. I will watch it again but essential I think a ballistic calculator takes into account all these variables, ballistic coefficient providing the time to target depending on angle and distance to accurately calculate the impact of gravity.
Gravity is approximated as always down for an air gun but not for an ELR shooter. Earth's surface drops 8 inches per mile, on a 3 mile shot that's two feet of drop. The force of gravity is straight down where you are standing but that line is not parallel with the direction of gravity if you're standing three miles away. In other words, if you're rifle is 1.5 feet above a still lake and you're shooting at a target 1.5 feet above the lake but 3 miles away you won't be able to see the target bullseye. And the direction of gravity varies as you traverse the trajectory.
So what is the horizontal distance in relation to this angle calculation if it is not 30m? It appears you have to set your scope distance to about 45m according to your ballistic table?
Why don’t you just admit it you and Ted are the best air rifle shooters that so far that I’ve seen because you guys are good at it enjoy your videos trying to word from you but it’s hard to learn old man new tricks sometimes course I got break barrel guns no guns like you got you and Ted are you guys got some real fine expensive guns that ain’t fair I’m laughing to
Surely the main reason the Rifleman's formula is not working is because you are trying to use the simplified version based on small angle assumptions at anything but small angles?
Hey , Mr. Pigeon , hold my beer while I figure out my angle of attack ! 😁 In hunting deer out of a tree stand with compound bows we had to practice our shots 16 feet up with different angle shots and distances , this to get familiar with the change in impact on a 3D moving target . They do offer a range finder for this but In most cases I never have time to use it .
Nice video Matt, enjoyed it a lot! Quite a far cry from shooting coins and disprins in your back yard, you have progressed very well in this sport! Where can we watch those old videos of yours, are they still available somewhere?
Unless I'm mistaken the guttering and roofing that the birds were sitting on looked like asbestos. Even if it's not I'm curious to know what are the rules of shooting around asbestos?
Optics Nerd alert! Comment on the Element teaser shots: Focus across the field of view is fantastic. My Aztec is garbage by comparison actually my Aztec is just plain garbage, my hawk scopes are more enjoyable to use. There is pretty significant chromatic aberrations (purple or blue fringing) 7:09 present however, aspherical fluorite coated lens would solve that =D all about price point vs perfection and price point they have. But alas its for hunting not photography. I really don't know the trade space the engineers had to make when putting it all together (that would be a neat side bar video /wink). When's the scope video's coming man? How well do they return to zero? I've been waitin!
Ok If you know what the arc is and you zero in to that. When you shoot as long as you know your distance to target the sight picture does not change. I.E. 30.06 arc is approximately 22 m & 230 m . Therefore anything under 230 aim 2" lower than normal and everything over 230 m. aim 3/4 " high and add 1 stadia line for every additional 50 m. But don't listen to me I have been shooting since I could walk. Give me three rounds where I can see the impact and I will stay there all day. Kentucky windage is my friend.

It’s always a big question for me how far a bullet will fly if I miss and what energy at the end.I think behind the building could be some people. May your thick book can explain this question?
Matt, could you consider doing a video on how you set up your range finder and kestrel; I have both, but my kestrel doesn't like airgun velocity and ranges. If you've already done one, a quick.link would be appreciated. Thx
Hi Matt, @ a pre primary school in town, we have a pigeon investation right above a sand pit. The kids are currently denied access to the sandpit due to the pigeon feces. How can we humanely handle this situation. Thanks!
Matt Thanks once again for your insights and thought. Question: Did I hear you say that only the Kestrel and the SiG rangefinder have the correct ballistic calculations in their software?
Strelok Pro does as well, since this post is 2 yrs later Strelok Pro has been updated with "Speed Drop Factor" which in effect makes your mil reticle act like a 'BDC' reticule. Check out "X-Ring" on line, very interesting. Matt would really get a kick out of this using his two center fire rifles... All you need is a quick range, and that is your hold!
Hi matt can you tell me what grain jsb do fx use to tune the impact before sending it out for sale I'm just curious I've just got an impact and I've put jsb 25.39 pellets in it and on factory settings before I've changed a thing the chronograph had it shooting 826 to 830 consistently so I was curious as to the weight they use? Thanks lee

Great work Matt!!!
Matt eating GOOD during this pandemic 😂
"Gravity not acting perpendicular when shooting at an incline"? ...wow Matt... is this the new physics here now?
Great job, yet again...
Thank you Sir...
Well that was a complete head-mash and explains why I missed so many rabbits the other week, which were all on inclines. Also didn't help that it was also 20mph winds.
Learnt a lot, now have a better understanding of the equipment you use
I'm a big fan of you, I watch every video of you
Thanks bro, the video is really informative, Please make a video on sight picture and sight alignment which covers different target ranges.
The time doesn't change much, only the force, hence correcting the drop (constant time, smaller force)
Very good vid Matt!

Matt, What ballistics software did you use to plot those Trajectories on the 1cm x 1cm blocks?
Gee this is how to do it: download a co-sign chart for slope angles then multiply the cosign for angle times line of sight distance.
Help me Whether the gun barrel has a 180 degree score or not
Anyone else notice the clop of the 1st shot. It went through the bird then through the roof behind it.

You should let Sig Sauer know that their AMR feature in the rangefinder is wrong. Unless I am misinterpreting what they say it is for.
Question: you keep referring to your distance (range) was 60meter. Is that horizontal or distance up to target?
Thanks great video
That is direct distance to target
@@AirArmsHuntingSA wait ... If you know your direct distance, there's no additional calculations needed
I read somewhere that this rule works only for slight incline angles (not more than 30°)
Most use 45 degrees (agree 30 is better). Past 45 - "rules" break down quickly.
