At 2:24 please revisit the graphic representation of bullet flight. Most all smallbore rifle barrels have been machined to twist the bullet clockwise as it leaves the barrel. Hence, a right hand twist. The arrows on the smallbore bullet are backwards. The image of the inside of the bore is a left hand twist. The slow motion video on the left show the correct twist of the bullet. Smallbore bullets fly to the right and down as they leave the barrel. A wind direction from the right retards the natural flight of the bullet and causes it to impact high and left or 10:00 o'clock. However, the best indicator of wind is mirage. It can only be seen with a spotting scope. Most international shooters forego the use of this perfectly legal piece of shooting gear and trust the flags, which are always late compared to mirage.
Just started shooting in 22LR matches and I notice this effect today. Didn’t know what was causing the bullet to drop when the winds swapped from right to left. Wish I saw this video explaining the affect the winds has on the bullets elevation. Great explanation.
@@airborne350g you may still not know what causes a bullet to strike somewhere other than where aiming. There are about 9 position/act of firing errors which can produce vertical groupings and none of these indicate an error in sight adjustment for wind. Here’s a fact to help you: the MOA wind constant for a .22 standard velocity round at 100 yard is 2 so using the formula distance to target in yards divided by 100 times wind value in mph divided by the constant of 2 you will understand where to hold. Let’s say you have a 3 mph crosswind. The formula would be 100 yards divided by 100 equals 1 times 3 mph equals 3 divided by MOA constant of 2 equals 1.5 MOA or about 1.5 inches of favor. Now since a 3 mph wind is almost impossible to observe it’s why most shooters do poorly at 100 yards and assume all sorts of things regarding the source of errors. Only when the shooter learns to call his shots and correlate to bullet strike via proper shooter/ target analysis will marksmanship develop.
Sidebar: my previous posts about wind having the most effect at mid range should be construed as mid range reading will give the shooter the best indication of average wind from shooter to target. For sure the wind at shooters firing point is only useful for calculation of a wind counter when what wind looks like at mid range cannot be observed via mirage or environmental effects. My perspective on this is as a CMP-USAMU Military Rifle Instructor assisting the USAMU deliver SDM Training, US Distinguished Rifleman, and American High Power Rifleman in Long-Range.
Who are the best shooters in the world? I’ll tell you, the United States Army Marksmanship Unit and their instruction says it’s the mid range wind that has the most effect on the bullet because that’s where the bullet is exposed to the wind for the greatest period of time. Now, I was trained how to shoot by the USAMU and adhering in all manner to their instruction, including appraisal of wind at mid range, I earned the prestigious US Distinguished Rifleman Badge in EIC Competition that includes 300 and 600 yard stages that do not permit sight-in shots, meaning to win these competitions requires perfect appraisal of wind. I also won the American High Power Rifleman Award in Long-Range, which required insane wind appraisal for the .308 round I was shooting in such competitions. In recent years I have been privileged as a CMP-USAMU Military Rifle Instructor to assist the USAMU deliver Squad Designated Marksman Training and guess what? That training instructs students to appraise the mid range wind. So there you have it, the best shooting in wind measures the wind velocity and direction at mid range. Results in the most demanding competition proves it.
It's just the other way around. The video is incorrect because it is based on a false statement: in the vast majority of weapons the bullets SPIN TO THE RIGHT, NOT TO THE LEFT, as he states in his video. It's about the Magnus effect, study it. It's confusing a lot of people.
А вы точно ничего не перепутали? Пуля которая вращается вправо будет сноситься выше при правом ветре, а у вас вращающаяся влево.( хотя выводы куда что вращается по вашим рисункам и видео летящей пули можно сделать совершенно противоположные ) не обьяснен также физический эффект этого понижения повышения при чистом боковом ветре.Если вы хотели обьяснить этот прыжок эффектом Магнуса ,то у вас ничего не получится.
Every empirical obervation and simulation for aerodynamic jump proves that for right hand twist bullet RISES with right to left wind and FALL with left to right wind... the opposite for left hand twist. Yet your stating the opposite! Why ? Do you shoot ? Do you know your rifling twist is right or left?
I respectively disagree with the statement that the closer flags are more important because of the angle of deflection increases down range. The bullet is at its fastest closer to the shooter, and will be deflected, but as it travels down range and losses velocity, the wind can affect it more. this can be seen as the bullet will hook. In your example, the down range flags show a stronger wind than the closer flags, thus, since the velocity is slower, and the wind stronger, the down range wind would move the bullet more. the chart showing the bullet deflection with wind strength is extremely well done. Thank You
Wind closest to the firing point normally has the biggest effect. A small deflection angle near the shooter becomes a much larger deflection further down range. Bullet speed wouldn't normally compensate tor this.
Suggest you google the paper "Where does wind matter?" by Dan Periard. Assuming uniform wind (a big assumption for the real world), close wind is *always* more impactful to the trajectory of a bullet.

How to shoot with headwinds throughout the match.

You are absolutely right and taking the mid range wind velocity and direction to determine wind counter need is what the USAMU teaches.
@@tomtucker83 USAMU results in long range shooting prove that it is appraisal and counter of wind at mid range which assures best results.
