    Arrow Trajectory Q?

    I was just curious if say you were shooting at an elevation of 4500 to 7500 does that affect arrow flight as your arrows would hit higher just curious if anyone knew anything bout it?

    I live at 6500 ft. and had base camp up at 9500 ft. this fall, from my sights nothing had moved when I shoot at either place. Just my 2 cents.

    It can but it will be different for everyone. I live at about 500ft and hunted at 12k ft in Colorado. I shot at the trailhead before we packed in and I didnt need to make any adjustments at all and I shot from 20-60 yards. Just take the time to do a little shooting before you start your hunt.
    The beatings will continue until morale improves.

    How did you do on your hunt.


    I live at 5200 ft shoot here and down at familys house a 3k with no change. I know that's not a huge difference but might help. Have to think though also, how much would it change with a rifle? I plugged my rifle load in the comp and with only variable being altitude, it did not change at 200 yds. 300 changed 1/4 inch and 1300 yds it changed 38 inches. I am assuming an arrow traveling 60 yards is not going to be a noticable change.

    I also did a 360 gr. bullet ( trying to match an arrow weight ) at 65 yards with a velocity of 1260fps (slowest I can make my program go) difference between sea level and 10000 feet was .01 of an inch. Same bullet at max speed program would allow (2007 fps) with same variables changed point of impact .56 of an inch so using that info I am likely to say the slower the speed, the less change in POI at different altitudes.


    Hope it helps.

    I live at sea level......when I backpack into the high-country (11,000' +) I am consistently 2" high at most ranges. I make the minor adjustment at trail head and am good to go. I probably see a significant difference over others here since my elevation gain is much more.

    BOHNTER, you say consistently 2" high. At what yardage? Or do you mean at all yardages? Before a few months ago I didn't think would be true for such short yardages (bow range), but the more I read im finding out that this may be true. Unfortunately I don't get to put it to the test where I live.

    Elevation should have no effect on your arrow flight. I sighted my matthews z7 in at sea level and shot my elk at almost 10000 feet. had zero effect on the flight.
    Its the spirit of the wild.

    Gravitational effects are the same, however the thinner air at higher altitude allows for less resistance which could affect trajectory. It will be different for everyones set up however.

    I generally checked my sight at 40 yards......it's almost always 2" high at 11,000'. I make the adjustment there (moving all pins simultaneously) and all ranges fall into line. In my experience, high elevation (11,000+) does have a slight affect on arrow impact depending on what elevation you sighted in at.
