.475 Linebaugh (Freedom Arms)

The .475 Linebaugh is a powerful large-bore revolver cartridge developed by John Linebaugh in the late 1980s, designed to provide significantly greater performance than traditional handgun cartridges while maintaining practical pressure levels. Its development marked a shift toward maximizing bullet diameter and penetration rather than relying solely on velocity. The cartridge quickly gained recognition among handgun hunters and enthusiasts, particularly when paired with high-quality revolvers produced by manufacturers such as Freedom Arms.

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, offering a substantial increase in frontal area over standard .44-caliber revolver cartridges. Freedom Arms revolvers, known for their strength and precision, are well suited to handle the pressures and performance levels of the .475 Linebaugh. Typical load data includes 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 and barrel length.

Freedom Arms emphasizes precision manufacturing and tight tolerances, which contribute to consistent performance and accuracy in cartridges such as the .475 Linebaugh. The cartridge is intended for use on large and potentially dangerous game, where deep penetration and reliable terminal performance are critical. Hard-cast lead bullets are commonly used for maximum penetration, while jacketed and controlled-expansion bullets are available for applications requiring increased tissue disruption. The moderate velocity of the cartridge supports predictable bullet behavior and effective straight-line penetration.

Recoil is substantial and requires experienced handling, particularly in lighter revolvers. Freedom Arms revolvers are typically built with strong frames and carefully designed grips to help manage recoil and ensure durability under heavy use. Despite its considerable power, the .475 Linebaugh operates at relatively moderate pressures compared to many high-performance handgun cartridges, contributing to its reputation for efficiency and mechanical reliability.

The .475 Linebaugh remains a respected cartridge among handgun hunters and large-bore revolver enthusiasts. As reflected in Freedom Arms applications, it represents a practical approach to achieving maximum revolver performance through bullet diameter, penetration and controlled pressure, maintaining its status as one of the most effective hunting handgun cartridges available.
