Does anyone have a bullet rise chart?
In pdf or a spreadsheet that i can put my elevation in and get the proper rise calculated? |

First reply nailed it. There is less air friction at higher elevations, but very little difference in the pull of gravity. |

Gravity is always working so bullets are always falling. They don’t rise. Also, gravity's effect on a bullet's trajectory is practically the same at any altitude you might shoot at. Air density at altitude is much more important. |

I don't think it's gravity but air density.

At a height of 10 km, gravity is 9.776 against 9.807 at sea level. That's a variation of 0.32% You are not going to be able to measure any difference in bullet drop; it falls well within the diameter of the bullet itself. |

I can see where this can be confusing, at extreme altitudes your bullet experiences less dense air so it loses velocity slower, you could experience less bullet drop at distance (I am far from expert at this)

Sighted in my 300 win mag at 2500 feet at 200 yards. Zeroed in.
Got to Utah at 7500 feet and I was shooting 6” too high at the same distance. Cause: 80% gravity 15% air molecules 10% air temp So E=MCHammer^87 Result:

Bullets never, ever rise.
They are free-falling objects, and subject to the laws thereof. |

OP,
Use a bigger bullet. Gravity will affect it more. Load up that 30-06 with some 220 grains. Will counter the bullet rise. |

It's 0.1% deviation from the sea level value. Unless you are doing indirect fire, it's not going to make a difference.

I guess they just don't teach this shit anymore.
You can inject modern precision bullets with different gases to change their performance. That's what that little hole in the tip is for on the OTM bullets. You can put helium in there to make the bullets rise more, or you can put something like carbon dioxide or sulfur hexafluoride in there to make the bullets drop faster, depending on what you're wanting to do. You have to be careful to not stick the needle in too far or you'll cause a leak and the gas won't stay in there. There's a PDF guidebook on how to choose the right gas and how to inject it properly. Should help you out, OP. Do a bit of searching it was linked here a while back. |

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. Physics much? |
