Quick Answer
The .416 Rigby generally exhibits a flatter trajectory and less wind deflection than the .300 Weatherby in long-range hunting scenarios, thanks to its heavier bullet weight and slightly slower velocity. However, the .300 Weatherby's higher muzzle velocity provides a slightly faster impact time. Ballistic performance ultimately depends on specific hunting needs and terrain.
Ballistic Comparisons
When comparing the two cartridges, we see that the .416 Rigby typically has a maximum point blank range (MPBR) of around 275-300 yards, while the .300 Weatherby’s MPBR is generally shorter at 175-200 yards. This is due to the .416 Rigby’s heavier 400-grain bullets, which retain their kinetic energy longer and maintain a flatter trajectory. The .300 Weatherby’s 150-grain bullets, on the other hand, have a slightly faster initial velocity but lose energy more quickly.
Hunting Realities
For hunting larger game such as elephant and Cape buffalo, the .416 Rigby’s heavier bullets and flatter trajectory make it a more suitable choice. Its slower velocity also reduces the likelihood of over-penetration in dense brush or vegetation. However, the .300 Weatherby excels in thinner terrain and for hunting smaller to medium-sized game, offering a better balance of power and recoil.
