.475 Linebaugh (Hodgdon Pistol Data)

The .475 Linebaugh is a modern large-bore revolver cartridge developed by John Linebaugh in the late 1980s, designed to deliver significantly greater performance than traditional handgun cartridges while maintaining practical operating pressures. It represents a shift in handgun cartridge design philosophy, emphasizing large bullet diameter and efficient energy transfer rather than extreme velocity. The cartridge has become well regarded among handgun hunters for its ability to provide reliable penetration and stopping power on large game.

The cartridge is based on a shortened and modified .45-70 Government case, adapted to function within revolver cylinders and optimized for large-frame handguns. It fires .475-inch bullets, providing a substantial increase in frontal area compared to standard .44-caliber cartridges. Hodgdon pistol data reflects typical loading parameters with bullet weights ranging from approximately 400 to over 500 grains, with velocities generally between 1,200 and 1,400 feet per second depending on the specific load, powder selection and barrel length. These ballistics offer significant energy and deep penetration while maintaining pressures appropriate for safe operation in properly designed revolvers.

Hodgdon emphasizes proper powder selection and consistent ignition when loading large-capacity revolver cartridges such as the .475 Linebaugh. The cartridge is intended for use on large and potentially dangerous game, where deep penetration and dependable terminal performance are essential. Hard-cast lead bullets are commonly used for maximum penetration, while jacketed and controlled-expansion bullets are available for applications where increased tissue disruption is desired. The moderate velocity of the cartridge contributes to predictable bullet behavior and effective straight-line penetration.

Recoil is substantial and requires experienced handling, particularly in lighter revolvers. Firearms chambered for the .475 Linebaugh are typically built with strong frames and carefully designed grips to manage recoil and ensure durability. Despite its high level of performance, the cartridge operates at relatively moderate pressures compared to many high-velocity handgun cartridges, contributing to its reputation for efficiency and long-term reliability.

The .475 Linebaugh remains a specialized but highly effective cartridge for handgun hunting. As reflected in Hodgdon pistol data, it continues to represent a practical approach to achieving maximum revolver performance through large bullet diameter, controlled pressure and reliable penetration, maintaining its place among the most respected large-bore handgun cartridges available.
