Hunting Energy Reference

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.

Data & Sources

Published BCs depend on a reference drag model and stated velocity conditions. A source review does not independently measure a BC. Understanding BC sources

  • Representative load: 400gr Hornady Custom XTP MAG
  • Velocity & BC: stored reference figures for the named factory load; verify against the manufacturer's current data
  • Trajectory & downrange energy: CaliberAtlas G1 point-mass model, for short-range reference — how we validate accuracy
  • Conditions: 59°F · 29.92 inHg · sea level · 50% RH · 1.5″ sight height · 50 yd zero
  • Case length: Specified maximum · SAAMI
  • SAAMI maximum case length is 35.56 mm; C.I.P. lists 35.16 mm. This entry uses SAAMI. C.I.P. reference

Your barrel, ammunition lot, and conditions will differ — always verify against the manufacturer's data and your own firearm.

Overview

The .475 Linebaugh is a specialized big-bore revolver cartridge built around driving heavy, large-diameter bullets at moderate velocity for deep, straight-line penetration. It is prized by handgun hunters pursuing the largest and most dangerous game, where its wide, heavy bullets deliver massive momentum and reliable pass-through performance on thick-skinned animals. The tradeoff is severe recoil, limited capacity, and chambering only in a handful of purpose-built heavy-frame single-action revolvers, which keeps it a niche choice for dedicated enthusiasts rather than general shooters. It is a short-range proposition compared to rifle cartridges, and its comparatively low ballistic coefficient means energy and trajectory fall off quickly past close hunting distances. Within its intended role, though, it has a strong reputation as one of the hardest-hitting revolver cartridges available.

History

The .475 Linebaugh was developed by revolversmith John Linebaugh in the mid-1980s and first widely publicized in a 1988 magazine article. It is based on a shortened .45-70 Government case firing .475-inch bullets, giving a big-bore round that fits in the five-shot cylinder of a properly converted heavy-frame single-action revolver such as those built on Ruger Bisley and Freedom Arms platforms. A big-bore round built for deep penetration on heavy game, it went on to become one of the defining "Linebaugh" chamberings and is offered as a factory loading by makers including Buffalo Bore.
