    Sighting in a .30-30

    Does anyone know the equivalent POI at 50 yards to achieve a POI of 3" high at 100 yards? I will be shooting 170 gr factory Winchesters. My local range only has 50 and 100 yard stations, and I would like to start at 50 to conserve ammo.

    Thanks.

    Somewhere around 1.5-1.6 inches high at 50 to be 3 high at 100 and back to dead on somewhere around 180-200 yards. Be sure to double check that on your range as your rifle/loads will be different than mine.

    If you know the actual muzzle velocity (you need a chronograph) and the ballistic coefficient of the bullet you can get a pretty decent approximation of the POI at 50, 100, 150, 200, etc. ranges. I actually do this on my handloads, then shoot at the 50 yard range to get it sighted in and a good grouping, then I move to 100 and 150 yards. With my 170 gr handloads, 1.4" high at 50 get's me approx 2.2" high at 100 and a 150 yard zero. But trying to center something at 1.4" is tough, so if I can get between 1.5" and 2" high at 50, then I'm good to go. I can bust milk jugs clear out to the 200 yard range.
