A ballistics chart comparing these cartridges visually represents trajectory differences, enabling assessment of their suitability for various shooting scenarios. Understanding trajectory variations is crucial for accurate shot placement, especially at extended ranges.
-
Bullet Drop
Bullet drop, the vertical deviation due to gravity, is a key factor. The .338 Lapua Magnum, with its typically higher ballistic coefficient and muzzle velocity, experiences less bullet drop over a given distance compared to the .300 Winchester Magnum. This translates to greater effective range and reduced need for elevation adjustments.
-
Ballistic Coefficient
Ballistic coefficient (BC) quantifies a bullet’s ability to overcome air resistance. Higher BC bullets, commonly used in .338 Lapua Magnum, are less affected by drag, resulting in flatter trajectories. The .300 Winchester Magnum, while capable, generally employs bullets with lower BCs, leading to more pronounced bullet drop at longer ranges.
-
Muzzle Velocity
Muzzle velocity, the speed at which the bullet exits the barrel, directly influences trajectory. The .338 Lapua Magnum generally boasts higher muzzle velocities, contributing to its flatter trajectory. While the .300 Winchester Magnum offers respectable velocities, the difference is apparent when comparing long-range performance.
