A 338 Win Mag Trajectory Chart is a vital ballistic resource that displays the vertical flight path and bullet drop of the 338 Winchester Magnum across common hunting and shooting distances. Because this cartridge is favored for heavy medium and large game, understanding its trajectory from 100 to 600 yards is essential for ensuring precise shot placement and ethical terminal performance. This guide utilizes verified factory ballistic data to demonstrate how various bullet weights and velocities interact with gravity at range. By studying these figures, hunters can effectively prepare for challenging shots in diverse terrain, minimizing the uncertainty often associated with high-powered magnum calibers.

To utilize this chart, identify your specific ammunition load and confirm that your rifle’s performance aligns with the listed muzzle velocity. With a 200 yard zero, the values indicate the vertical holdover required at each distance. For example, when using the 225 grain Hornady SST load, you should hold 19.2 inches high at 400 yards to compensate for bullet drop. Always verify your rangefinder readings and local atmospheric conditions, as wind and altitude can alter these baseline figures at extreme distances.
Understanding The 338 Win Mag Trajectory Chart
The data in the trajectory table provides a practical reference for field performance. Understanding these metrics helps you anticipate the bullet’s arc and ensure accurate engagement.
Trajectory Analysis
Comparing the 210 grain Federal Partition to the heavier 250 grain Sierra MatchKing shows how mass and velocity affect downrange performance. At 500 yards, the 210 grain load drops 35.2 inches, whereas the heavier 250 grain projectile drops significantly more at 41.8 inches. This illustrates that while the 250 grain bullet provides superior sectional density, the 210 grain load offers a flatter path for hunters prioritizing mid-range precision.
Velocity Analysis
Muzzle velocity is crucial for maintaining a flat trajectory with a heavy magnum cartridge like the 338 Win Mag. The 200 grain Winchester Power Point starts fast at 2950 fps, which keeps its drop minimal—only 53.8 inches at 600 yards. Conversely, the 250 grain load starts slower at 2660 fps, leading to a steeper trajectory that requires more precise compensation at long range.
Ballistic Coefficient Analysis
The ballistic coefficient (BC) is the primary factor in how well a projectile retains its velocity against air resistance. The 225 grain Nosler AccuBond, with a high BC of 0.550, retains its energy better than the 225 grain Barnes TSX (BC 0.430). Even with identical weights, the AccuBond drops slightly less at 600 yards (56.6 inches) compared to the TSX (61.4 inches), proving that aerodynamic efficiency is just as important as bullet weight.
Best Factory Loads Based On The Chart
For big game hunting where distances vary, the 225 grain Hornady SST and Nosler AccuBond represent the best all-around factory options, offering a balance of high ballistic coefficient and manageable drop. For hunters targeting larger game at closer ranges, the 250 grain loads provide unmatched terminal energy. For shooters who prioritize the flattest possible trajectory for mid-range hunting, the 200 grain Power Point load is the top performer according to our drop data.
Key Takeaways From The Chart
The 200 grain Winchester Power Point is the flattest shooting load at 600 yards with only 53.8 inches of drop. The 225 grain Nosler AccuBond provides the best ballistic coefficient at 0.550, making it the most efficient load for retaining velocity downrange. The 250 grain load is the most robust option for large game where energy retention and deep penetration are prioritized over a flat trajectory.
Common 338 Win Mag Bullet Weights
The 338 Win Mag is designed for versatility, handling a range of heavy bullets effectively.
200 Grain
These are the fastest factory options for the 338 Win Mag. They offer an exceptionally flat trajectory for this caliber, making them perfect for hunters who may need to take shots out to 300 yards. Their disadvantage is a lack of deep penetration compared to heavier bullets.
210 Grain
The 210 grain weight provides a good balance for hunters who want high velocity without sacrificing too much terminal power. It is a favorite for those who need a multi-purpose load that handles both deer and larger game effectively.
225 Grain
This weight is arguably the most popular for 338 Win Mag users. It offers excellent ballistic coefficients and consistent terminal performance on large animals. It is the recommended choice for hunters who need reliable performance out to 400 yards.
250 Grain
The 250 grain bullet is the heavy-duty standard for this cartridge. While it produces the most drop, it provides massive kinetic energy and is the preferred choice for hunting larger, thick-skinned game where deep penetration is critical.
Effective Range
Big Game Hunting
For animals like elk or moose, the effective range is roughly 400 to 500 yards. Beyond this, the bullet drop (reaching over 35 inches) makes accurate shot placement on vital organs significantly more difficult.
Long Range Shooting
The 338 Win Mag remains accurate on steel targets out to 600 yards and beyond. Experienced shooters who track their specific load’s drop values can achieve consistent results, provided they have a solid understanding of wind conditions.
Factors That Affect 338 Win Mag Trajectory
Bullet Weight
Heavier bullets offer better wind resistance and energy retention but suffer from a more pronounced arc. The data confirms that shifting from 200 to 250 grains increases the 600-yard drop by nearly 15 inches.
Muzzle Velocity
High velocity is essential for the 338 Win Mag to perform well at range. Any reduction in velocity, whether due to barrel length or atmospheric conditions, will require you to increase your holdover.
Ballistic Coefficient
A higher BC is the key to long-range efficiency. The Nosler AccuBond’s superior BC allows it to drop less than the Barnes TSX at 600 yards, despite them both starting at 225 grains.
Wind
This cartridge is heavy enough to resist moderate wind, but at 500+ yards, wind drift will become the primary cause of missed shots. Always use a high-BC load to minimize this effect.
Frequently Asked Questions
