    Good Morning,
    I have been shooting for about a year now and most of my shooting has been at IDPA and a 50 foot range I joined. My question since my gun has been sighted in at 50 feet what distance could I expect my gun to maintain it's accuracy. I am shooting a Commander 45. I realize that the hotter the ammo the longer the distance would be and I also realize that without specific numbers it's hard to give a answer but lets asume that a velocity of around 825-850 as a number as this would be my IDPA LOAD.
    Thanks mike

    If I remember this right, if your point of aim =s point of impact at 15 yards (45 ft), the bullet will still be rising a bit at 25 yards, be nuts dead on again at around 50 yards, and about 6-8 inches low at 100 yards.

    Your question was about 'accuracy', I answered with 'trajectory'. I think thats what you were asking.

    If I'm wrong, someone will came along a bit later to correct whats left of my faulty memory cells.

    There are other groups/forums that deal specifically with exterior ballistics. You might get a more definitive answer there. But you would probabaly also need to provide more information.

    Personally, I can't hold and squeeze well enough to tell much of a difference.

    salty.

    You didn’t say what weight or style of bullet, so I’ll assume your using a 230gr RN. So with a Ballistic coefficient of .189, velocity of 837.5, sight height of .7, if you zeroed a 51 feet (17 yd) you would be -.2 @ 25yd 821fps, -.5 @ 30yd 818.3fos, -1.4 @ 40yd 811.9fps and -2.8 @ 50 yd 805.5 fps.
