Jim MoseleyAt what range does the coriolis effect begin to take effect and do different compass headings have more bearing than others on bullet placement? |

Nathan FosterRe: Coriolis Effects#The observed effect of the Coriolis force, especially the deflection of objects or substances (such as air) moving along the surface of the Earth, rightward in the Northern Hemisphere and leftward in the Southern Hemisphere. The Coriolis effect is named after the French engineer Gustave Gaspard Coriolis (1792-1843)#The above definition pretty much says it all. A big problem if firing a ballistic missile from the equator to the poles, not so much of a problem when using a rifle. I don't know how this term came to be used in rifle ballistics. Yet I hear the term bandied about occasionally. Its a fair question Jim- seeing as we do hear about it. I think the most succinct answer could be- A variable in long distance shooting which comes into play when a shooter reaches a level of intellectual snobbery which causes his head to go so far up his behind as to cause verbal diarrhea. At our latitude, the earth moves roughly 352 yards per second. It takes about 1.5 seconds for the bullet to reach 1000 yards. Fortunately, I do not have to dial in 528 yards windage. It seems that when I fire my shot, all of these variables are relative. So I don't know why folk worry about the coriolis effect when long range shooting. You would also have to calculate north south orientation and lattitude for each shot if running with the coriolis effect. |

Jim MoseleyRe: Coriolis EffectsThat's the best explanation I've heard so far :-) My wife will attest to the fact that I'll never reach the "intellectual" level!! She tells on a regular basis to stopping thinking. Thanks for the answer....I'll sleep better now! Have a good day! |

Nathan FosterRe: Coriolis EffectsHa, our lovely women, keeping us in line. Steph said to me this morning, that if we were at the mercy of 528 yard per second force, we would be pulling some serious G-forces. She was walking across the room, head down, like she was walking into a hurricane saying "curse this coriolis effect". |

jason brownRe: Coriolis EffectsI liked that explanation too Nathan. iv never worried about it, and so I will carry on. |
