Wind Quiz

[taliv]

mozilla, they believe that force is the resistance of the air. (drag)
i.e. they believe the force of the gunpowder burning only ever causes the bullet to move parallel to the bore. completely separately, wind acts at 90 degrees and is counteracted by air resistance, so that when the wind stops, eventually the air friction stops the lateral motion, leaving the projo only moving again parallel with the bore.
essentially, they do not believe the wind redirects the bullet, so the momentum from the burning gunpowder is pushing the bullet at an angle.

Yup, put a fan on the floor and roll a marble in front of it.

Seirra infinity software has had the ability to solve this question for quite a while.

Nope, marble isn't stabilized by spinning. The marble will change direction, the spinning bullet will move sideways but WILL NOT change direction.

You can look at flags all you want at are range, but you will never be dead on. If you are lucky you will maybe shoot 12" in a wind like we had Sunday. All I can tell you if your rifle won't shoot through it, better get one that will. If you have the wind picking up and letting off, your in trouble no matter were you shoot.
Victor at our range if you are on bench 1 and the wind is blowing from left to right you have a better chance of winging because the trees block the wind for about 400 yards. Look at the results on www.pa1000yard.com between L.G. and H.G. Saturday the wind blew from left to right, then Sunday from right to left.

match looks like same as always early matches no wind then later matches wind picks up my brother shot smallest group of the day one year by shooting 1st relay,but I see on light gun the wind was low early then picked up late, heavy gun the wind was howling I see your point GOOD SHOOTING IN THAT 1ST RELAY THOUGH A++

They will both change direction.

LOL.... Near wind and Far wind question?

Both are important but the wind with no wall towards the end of it's flight would be effected the longest by the wind bc it has slowed down and will be in the air longer. The bullet will be slower so more susceptible to wind. However, Near wind is the most important bc it is the only KNOW wind. You can read it at the muzzle but not down range and not 30 feet in the air.

Good question.

Good question.

Actually, the wind closest to the shooter has the most effect on lateral impact downrange, not the wind closer to the target.

Because little off at the muzzle a lot off at target? "The total deflection is more dependent on how the bullet is affected early in it's flight." I just went back to Bryan's book and looked it up. Thanks.

Bryan, Bryan, Bryan I wish I wrote a book! I think I said that in my first post. I'm a liar like HILLARY.

According to Litz, the best assumption would be that shooter B has the most deflection due to the bullet continuing on its altered path for the entire trajectory. I believe.

OK.....bullet is fired at 90 degrees to the target berm. The bullet is spinning at a gazillion rpm. A right to left wind will push the bullet left BUT will it cause the bullet to point left OR will the spinning bullet be moved laterally while still heading at 90 degrees to the target berm.
A canoeist is crossing a river with parallel banks. He pushes off in calm water heading 90degrees to the opposite shore. One third of the way across he encounters a downstream current flowing from right to left. The current carries him downstream but two thirds of the way across he again encounters calm water.
He departed from point A heading for point B which was directly opposite his point of departure but he will make landfall at point C which will be downstream of point B. The distance downstream will equal the distance the current carried him while he was in the moving water.
