Quick Answer
.416 Rigby can be reloaded for specific game conditions with the right expertise and equipment.
Reloading for Large Game
The .416 Rigby is known for its effectiveness on large and dangerous game, such as elephant and Cape buffalo. To reload this cartridge, you’ll need a press capable of handling large cases, like the RCBS Pro 2000 or the Lyman Pot Gun. A suitable powder, such as Hodgdon H4198 or IMR 416, is necessary to achieve the desired velocity and pressure.
Reloading for Heavy Bullets
When reloading the .416 Rigby with heavy bullets, it’s essential to pay close attention to case capacity and powder load. A maximum overall length of 2.85 inches is recommended to accommodate heavy bullets and ensure reliable feeding in the chamber. A good starting point for heavy bullets is 70-75 grains of powder, which will result in a muzzle velocity of approximately 2,200-2,300 feet per second.
Safety Considerations
When reloading for the .416 Rigby, it’s crucial to follow safety procedures to avoid overloading the case or exceeding the maximum permissible pressure. A good rule of thumb is to start with a 10% reduction in powder load and work up gradually to the desired pressure. Additionally, always use a reliable chronograph to measure the muzzle velocity and ensure that the round is safe to fire.
