Here are some ballistics I got from "shootingtimes.com"
.338 Win Mag
Bullet Weight 250
Muzzle velocity 2800
Velocity at 500 yards 1920
Muzzle Energy 4350
Energy at 500 yards 2035
Trajectory at 100 yards +1.8
Trajectory at 500 yards -44.9
.338 Lapua Magnum
Bullet Weight 250
Muzzle velocity 2690
Velocity at 500 yards 1822
Muzzle Energy 4420
Energy at 500 yards 2028
Trajectory at 100 yards +2.0
Trajectory at 500 yards -49.5
For the same bullet weight The win mag has a slightly straighter trajectory compared to the lapua and carries as much energy as the lapua at 500 yards
Let me know why I should chose the Lapua bullet over the win mag
