I know that the higher elevations out west can make the point of impactdifferent than what I sighted in at.My questionis,does anyone know about how much it'll throw your bullet off?Say if I sight my 7mm rem mag in at 3" high at 100yds(here in Ky),about how would be out west say around 6000'-7000'.I know there is no substitute for checking what it is actually doing when I get to camp.Just trying to get an idea of what to expect when I get out there.
I have hunted at elevations form 6,000 to 12,000 feet for elk. I am sure someone can bring out a chart and tell you what should happen. But when I checked my rifles out west they hit the same. But I will admit that we did not shot at any distance over 300 yards. And when we normally checked our rifles we were usually around 7,000 feet. I never had an opportunity to check my rifle at 12,000 feet. And that would have been a problem if my rifle was high at that elevation. Long shots were available at that elevation, because we were out of the timber. But the opportunity never arose at that elevation. If you are hunting at 6,000 to 7,000 feet then I do not think you will see that much difference. We didn't. Tom.

Best thing to do, regardless of the elevation is to check your rifle's POI when you arrive. Technically, the higher the elevation, the less wind resistance and therefore a higher POI. But honestly, you may only experience 1 or 2 inch difference if any.

Agreed...I usually check my deer rifle every 3-4 weeks of the season, even if I don't take a trip...
There isn't a rats a** difference at normal hunting distances all the way to 10,000 feet. What matters is your shooting ability, using the correct holdover for the distance encountered and having a proper rest.

It makes a slight difference if you are zeroed at a lower elevation. I do all of my shooting at Denver's elevation, and I still stop and take a few shots at a mountain range before we head to camp. The longer the shot, the more you will notice the difference. You have spent a ton of dough, and a lot of time, take a few minutes and double check your zero!

The changes are mostlydue to changes in barometric pressure, nothing worth noticing till the range exceeds 700 yards. the greatest effect just altitude can have on a bullet is less than 2" at 1000 yards.
the higher the altitude the thinner the air so even at the same conditions the bar pressure is lower up high. Bar pressure actualy changes your bullets BC, which changes its flight characteristics.
at normal hunting ranges angle of fire will effect your POI more than altitude, such as extreme uphill downhill shooting.

Wind drift and KE is affected more downrange than trajectory is at higher altitudes. The amount of wind drift(especially with lower BC bullets) decrease quite a bit at high elevations.
high elevation question.
