Extended predictions beyond 500 yards are modeled from the same G1 engine — useful for initial DOPE, but outside the 500-yard manufacturer-table validation audit. Confirm with observed DOPE, especially near transonic.
A retained-energy reference only — not a shoot/don't-shoot distance. Real effective range depends on your accuracy, shot placement, bullet construction, and conditions. The ~1,000 ft-lb (deer-sized) and ~1,500 ft-lb (elk-sized) figures are commonly cited rules of thumb, not standards.
Published BCs depend on a reference drag model and stated velocity conditions. A source review does not independently measure a BC. Understanding BC sources
Your barrel, ammunition lot, and conditions will differ — always verify against the manufacturer's data and your own rifle.
The .375 H&H is widely regarded as one of the most versatile dangerous-game cartridges ever made, capable of taking everything from plains-game antelope with lighter bullets to buffalo, lion, and elephant with heavy 300-grain solids and softs. Its reputation rests on a balance of adequate power, manageable recoil for a big bore, and famously good feeding from the long, tapered case. Hunters and professional guides value its flat-shooting character relative to other stopping-caliber cartridges, which lets it double as an all-around choice where a single rifle must cover both large and dangerous animals. Its main limitations are the heavy recoil and muzzle blast inherent to the class and the need for a long (magnum-length) action to accommodate the cartridge. Effective within typical hunting ranges, it endures as a standard against which other medium bores are measured.
Introduced by the British firm Holland & Holland in 1912, the .375 H&H Magnum was among the cartridges that used a belted case and helped popularize the "magnum" designation. It was designed as a versatile large-bore round for dangerous game, built on a long, gently tapered case with a distinctive belt for headspacing. More than a century on, it remains a benchmark medium-bore cartridge and is the legal minimum caliber for hunting dangerous game in many African jurisdictions.
