About .30 Super Fl. H&H
The .30 Super Flanged Holland & Holland (H&H) is a classic cartridge developed in the early 20th century by the renowned British gunmaker Holland & Holland. Designed specifically for use in double rifles, it features a flanged, or rimmed, case, making it ideal for break-action firearms. It was created to meet the demand for a high-performance round capable of taking medium to large game, particularly in Africa and India. Its development is rooted in the golden age of safari hunting, where reliability and stopping power were paramount.
Technically, the .30 Super Fl. H&H features a case length of approximately 2.5 inches with a rim diameter suited for double rifles. It is typically loaded with bullets in the 150 to 180-grain range, providing a balanced performance between velocity and energy. This makes it versatile for a variety of hunting scenarios. The cartridge delivers a moderate muzzle velocity and energy compared to its belted and more modern counterparts, offering a gentle recoil that aids in maintaining accuracy in rapid shooting situations common in double rifles.
Ballistically, the .30 Super Fl. H&H is considered a moderate cartridge by today’s standards but remains effective for hunting purposes. Its efficient performance at ranges typically used in traditional safari-style hunts makes it a preferred choice for hunters valuing classic firearm design. Its flanged case supports reliable extraction and feeding in double rifles, a notable advantage when employing rapid follow-up shots in dangerous game hunting.
For reloaders, the .30 Super Fl. H&H presents advantages due to its manageable pressure and the availability of high-quality reloading components. The cartridge's historical significance and uniqueness make it an appealing choice for enthusiasts interested in classic hunting rifles. Reloaders can experiment with bullet weights and powder combinations to optimize performance according to specific hunting needs or preferences, all while maintaining the narrative and craftsmanship emblematic of Holland & Holland’s storied legacy.
