The station pressure at 10k is 20.58 in/hg, 29.92 in/hg at sea level all other atmospherics are unchanged in the above. |

And another thing-the Earth has a rotational speed at the equater of about 1,000 mph. So if you climb to the top of a really high mountain you will be flung into space by centrifugal force. That's why nobody lives on top of those mountains even though the street value of all that pure snow must be incredible. View Quote |

Quoted:
Do you even physics? Acceleration due to gravity is a constant. View Quote View All Quotes View All Quotes There is a tiny bit less gravitational attraction at altitude. More importantly, there is some difference in the gravitational constant from place to place, independent of altitude, having to do with the density of the country rock and what is happening with tectonic plate/plates beneath your location. In other words, there is very, very little (read: almost nil) difference between shooting at altitude due to gravitational effects over shooting at sea level. I suspect the reduced air pressure is far more influential than the reduced gravity. |

I see a lot of bullet drop compensation computations but cant recall seeing a bullet rise computation. With gravity being less effective at really high altitudes above sea level (10k' or more), I would think that we should have a book to help shooters account for this. View Quote ![]() |

That's why nobody lives on top of those mountains even though the street value of all that pure snow must be incredible. A side note is that the Sun's gravity attracts objects on the Earth. So during the "day", most notably when the Sun is directly overhead, everything on the surface of the Earth is pulled towards the Sun. We call this direction "up". Ever shoot at a distant target and not hit it? Have no idea where the shot went? Yep, that's right, it's on it's way to the Sun. This little-known fact is great news for dieters. Simply weighing onesself in the middle of the day can take several pounds off. Isn't gravity great? People don't think it be like it be but it do. |

But if it’s raining it lubricates the bullet, reducing the coefficient of friction, and it accelerates. View Quote View All Quotes View All Quotes Quoted:

if this isn't a parody thread, the Hornady 4dof ballistic calculator takes into account altitude https://www.hornady.com/team-hornady/ballistic-calculators/# To calculate trajectory, you need to know elevation and temperature. On a hot, dry day in AZ, a bullet will hit higher than on a cold day. Density altitude is a real thing, and if you fly a small plane, you know all about it. Thin air vs thick air. |

Quoted:
Gravity does affect bullet drop but isn't the only thing. A 55gr m193 at 3250fps out of a 1/7 twist barrel is rotating at ~334,000rpm. Gyroscopic stabilization affects trajectory, to some extent counteracting the gravitational effect. Additionally. The presence of a treadmill at any point in the projectile's flight will deflect the bullet in unpredictible ways. Lastly, the Bernoulli effect created by the rapidly moving projectile creates lift, also slowing acceleration towards the ground. So calculating bullet drop is much more complex than a simple gravitational acceleration. View Quote |

Quoted: I don't think that means what you think it means. In the sense of ballistics, bullets are known to go faster as the body weight of the shooter goes up. It's why you see a lot of really fat gun guys. Less bariatric pressure is a BAD thing. View Quote |

OPs not lying, guys, haven’t y’all seen this chart?? https://www.AR15.Com/media/mediaFiles/293861/EE40D193-4421-479D-9D15-286275D94091_png-747230.JPG View Quote Shooting in mountainous country, your shot will be many times more affected by the angle of the bore to the horizontal than by any other factor. Shooting up and down hills is an art that requires study and practice. There might be ballistic charts for this in certain hunting rifle calibers but essentially you can miss by a mile if you don't have a pretty good idea of what you're doing. |

Quoted: So i guess you cant help with my bullet rise data sheet. ![]() View Quote I just know that after all the holidays I’m going to want to lose weight. In the past I’ve never been as successful as I’d like so thanks to you & this thread I now know exactly how to proceed. I’m going to start the ‘diet’ at the seafood buffet at The Shepherd on Clearwater Beach FL, then get my stating weight. I’ll then eat my way towards Pikes Peak Co where I’ll get my finish weight. Quick snack after & then look forward to a year knowing I’ve lost weight! |

While 10,000 feet makes no difference on ballistics as far as gravity is concerned it makes you wonder about the ballistics in zero g. If you shoot a bullet in space would it have a flat trajectory? View Quote I love these threads, I learn so much they never taught me in physics. |

Because the bullet's path will be some form of arc, it will intersect the line of sight on it's way to it's highest point, and again wherever it is zeroed. If zeroed at 200 yards, it will be below the line of sight at the muzzle because of the scope's height over the bore, then it will intersect the line of sight around 25-50 yards, then it will be an inch or two high at 100 yards, and strike the line of sight at 200 yards (roughly).
