How the wind effects a small bore bullet. Reading the wind flags on an international shooting range.

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.

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.

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.

You know the effect of the wind on a bullet but has it wrong on the reason why a bullet impact higher or lower because of side wind.

@@heinzlive I have a pdf on my computer explaining aerodynamic jump because of crosswind. As you know I cannot post a pdf here on YT. So while traveling as a passenger I searched for the pdf on the web. I also cannot post a link here. If you type in the following you will find it.: Hornady 4 Degree of Freedom (4 DOF) Trajectory Program. The thing that you said that a bullet speed up or down with a crosswind is wrong. Since you a using .22LR you might be busy with air rifles as well. What works for a spin stabilisation bullet or slug work exactly the opposite for a drag stabilisation air rifle pellet. I hope this helps

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.
