My grandfather told me today that if I have a scope on a rifle, to shoot at a target 13 1/2 yards away. Then adjust the scope to the bullet hole, then it will be on at 100 yards. He said that he read it in a book, it even had a picture showing this. He said that "THIS" book stated that the bullet comes out the muzzle straight for 13 1/2 yards before it starts to make an upward arc. Is this true? Anyone heard/read anything like this?
13 1/2 yards????

bullets follow a path of a parabolic arc, but all vary depending on the weight, charge, shape of the bullet. however, zero'ing at 13.5 yards should nicely put you on paper at 100 yards.
most fire a three to five shot group and take the average when zeroing to reduce the possibility of shooter error or other inconsistancies. myself I usually start at 25 yards.

Bullet do not make an upward arc when they leave the barrel unless the barrel is bent upwards. Bullets start to drop as soon as the leave the barrel.
The reason people think the bullet arcs upward is because the sights/scopes are above the bore and in order to hit point of aim the barrel it actually pointed slightly upwards.
Having said that, by starting to sight in at 25 yards will save you a pile of ammo.
