Trajectory
Long Distance Shooting
Since both ammo are known for extreme long-range shooting, comparing their trajectory could be a little tricky. Although the 300 Winchester Magnum is notable for its accuracy and has been used for 1,000-yard – 1,100-yard competitions, the 300 Remington Ultra Magnum exceeds its performance in the long-range shooting because of its flatter trajectory.
