Quick Answer
Reliability for dangerous game is achieved through a double rifle's ability to fire two cartridges in quick succession, a robust receiver design, and a high level of craftsmanship in the lock and barrel. This setup allows for rapid follow-up shots and increased stopping power. A good double rifle also features a strong, well-designed stock that helps to reduce recoil.
Design and Receiver
A reliable double rifle for dangerous game should have a robust receiver designed to handle the stresses of firing high-powered cartridges. This often involves a large, sturdy action with a strong pivot point for the hammers. For example, the Holland & Holland Royal rifle features a massive receiver with a .700-inch pivot pin, capable of handling the stresses of .500-caliber nitroexpress cartridges firing at up to 2,000 pounds per square inch.
Lock and Barrel
The lock and barrel of a double rifle are critical components in achieving reliability. A good double rifle should have a strong, well-designed lock with a robust sear and hammer system. The barrel should be accurately aligned and securely fastened to the receiver, with a reliable extractor system to ensure smooth ejection of spent cartridges. For example, a well-maintained double rifle with a good lock and barrel can achieve accuracy of 1 inch at 100 yards.
Stock and Handling
A good double rifle for dangerous game should also feature a strong, well-designed stock that helps to reduce recoil and improve handling. This can be achieved through the use of a well-fitting stock, a recoil pad, and a well-balanced weight distribution. For example, a double rifle with a stock weighing around 3-4 pounds can help to reduce recoil and improve handling, making it more suitable for use in the field.
