Quick Answer
The .416 Rigby is generally considered overkill for most plains game hunting, as its 400-grain bullets deliver more than enough kinetic energy to drop most medium-sized and large game at close to medium ranges.
Ballistic Characteristics
The .416 Rigby’s 400-grain bullets typically travel at around 2,200 feet per second and have kinetic energy of over 3,500 ft-lbs at 200 yards. While this excessive energy can be beneficial for larger or more aggressive game, it can also result in over-penetration and excessive tissue damage on smaller or more fragile animals. In these cases, a more modest cartridge such as the .416 Remington Magnum or the 9.3x62mm might be a better choice for controlling the game’s impact zone.
Practical Considerations
In reality, plains game such as impala, kudu, or wildebeest rarely require more than 100-150 yards of range to be brought down. At these close ranges, a .416 Rigby can be overkill, as the animal will likely be dropped with a smaller, more practical caliber. However, in certain situations, such as hunting more aggressive or larger game like eland or buffalo, the .416 Rigby’s power can be beneficial for delivering a quick and humane kill. Hunters should carefully weigh their options and choose the right cartridge for the specific hunt.
