History
Ruger and Hornady jointly developed the .416 Ruger as part of their Ruger Compact Magnum (RCM) initiative in 2008. The goal was a dangerous game cartridge that could be chambered in a hunting-weight bolt action without the length and weight penalty of .416 Rigby or the belt of .416 Remington Magnum. The result matched .416 Remington performance in a standard-length action using a modern beltless case. The Ruger Hawkeye African and Safari models were chambered in .416 Ruger; Hornady produces Dangerous Game Series ammunition. It has found a solid following among professional hunters and serious dangerous game hunters who want a lighter, more agile rifle than traditional choices.
