How do bullet weights affect trajectory with .338 Federal in elk hunting?

Bullet Trajectory Considerations

When hunting elk with the .338 Federal, bullet weight significantly impacts trajectory. In general, lighter bullets (200-220 grains) have less drop at long ranges due to their lower sectional density and higher BC (ballistic coefficient). For instance, the 200-grain Nosler AccuBond has a BC of .565, whereas the 250-grain Nosler AccuBond has a BC of .485. This results in approximately 10-15 inches less drop at 500 yards for lighter bullets compared to their heavier counterparts.

Wind Drift Considerations

Heavier bullets (250-300 grains) tend to exhibit less wind drift due to their higher sectional density and more aerodynamic shape. For example, the 250-grain Sierra GameKing has a more streamlined design, resulting in approximately 5 inches less wind drift at 500 yards compared to the 200-grain version. This makes heavier bullets more suitable for long-range hunting in windy conditions.

Bullet Weight Selection

Elk hunters often prefer heavier bullets for their deeper penetration and larger diameter. However, lighter bullets may be preferred for their flatter trajectory and less wind drift. Ultimately, the choice between a 200-220 grain or 250-300 grain bullet depends on the hunter’s personal preference, the terrain, and the expected shot distance.
