.465 H.& H. Belt. Mag Load Data

The .465 Holland & Holland Belted Magnum, often simply known as the .465 H. & H. Belted Mag., has its roots deeply embedded in the early 20th century, when advances in cartridge and rifle technology allowed for the creation of powerful magnum cartridges purpose-built for African big game hunting. Introduced in 1907 by the esteemed British gunmaker Holland & Holland, the .465 H. & H. Belted Magnum was designed as a proprietary chambering for the finest double rifles. The goal was to provide a round with more striking energy and improved penetration over earlier black powder express cartridges, largely in response to new regulations banning the use of military calibers like the .450 for hunting in British colonies. Characterized by its high velocity for the era, deep-penetrating capabilities, and the innovative use of a belted case for secure headspacing in double rifles, the .465 H. & H. quickly earned a reputation among professional hunters and sportsmen traveling to Africa and India.

Today, the .465 H. & H. Belted Magnum retains its legendary status as a top choice for hunting dangerous big game. Its applications are squarely focused on ensuring reliable stopping power in the most intense and hazardous conditions. Primarily chambered in break-action double rifles, the .465 H. & H. is favored where rapid follow-up shots and absolute dependability are crucial—such as in close-range encounters with Cape buffalo or elephant. Its power ensures deep penetration through tough hide and bone, making it especially valued by professional hunters (PHs) and guides operating in areas with large, thick-skinned game. Although modern bolt-action magnums have become common, the .465 H. & H. remains a gold standard among traditionalists and serious hunters intent on classic safaris or those seeking the quintessential African double rifle experience.

When it comes to target species, the .465 H. & H. Belted Magnum is purpose-built for Africa’s largest and most dangerous animals. This includes elephant, Cape buffalo (Syncerus caffer), rhinoceros, and occasionally lion, where extreme power and bullet performance are paramount. Its role is not for medium or light game, nor is it suited for plains game or typical North American hunting situations. Instead, its considerable recoil and stout performance are focused on providing the necessary energy and bullet integrity to deliver deep, straight-line penetration for heavy, dangerous targets—where failure is not an option and lives can depend on a cartridge’s reliability.

For reloaders and enthusiasts, the .465 H. & H. Belted Magnum typically utilizes bullets in the 480-500 grain range, most commonly around 480 grains. These projectiles are available in a variety of constructions, including solid (non-expanding) bullets for maximum penetration and expanding soft-point designs for shock and tissue damage. Typical muzzle velocities hover around 2,150 feet per second, yielding energy levels in excess of 4,900 foot-pounds at the muzzle. The cartridge is identifiable by its long, rimless (but belted) case, which promotes positive extraction in double rifles. Recoil is substantial; hence, rifles are often fitted with robust stocks, thick recoil pads, and sometimes additional weight to help manage the powerful shot. Brass is generally manufactured by specialty firms, and high-quality, heavy-walled cases are essential for safety and longevity. The caliber’s niche appeal ensures it remains a favorite for reloaders who appreciate classic British engineering, tradition, and the thrill of dangerous game hunting.
