I use a 30-30 on occasion and if I remember correctly, I sight in 1.5" high at 100 yards. That gives me 0-150 yards and still be in the kill zone.

Remington' s web site lists trajectory, and you can compare different weights and different calibers against each other.
I would guess most ammo manufacturer' s sites do the same.

Remingtons website has a program you can download called Remington shoot (it' s free). While it only gives you rems factory loads it will give you an idea and starting point for which to head to the range with. 1.5" high at 100 should put you close to zero at 100 with a 150gr bullet.
