RE: cva buckhorn
Well no rifle technically shoots flat.. also how flat they shoot will depend on the load and the bullet you shoot. All of them have a rainbowtrajectory of sortsto them, its just a matter of how big an arch they make. I really would not worry about how flat it shoots. Learn what projectile it likes and then practice out to the distances you might encounter. If the rifle is sighted in at 100 yards, you know where that bullet will hit. All you need do is figure out the drop or climbof the different distances. That's done through range time.
