.400 Legend

The .400 Legend, also called 400 LGND, is a SAAMI-standardized straight-walled intermediate rifle cartridge developed by Winchester Repeating Arms. The cartridge was designed for use in American states that have specific regulations for deer hunting with straight-walled centerfire cartridges. It is designed for deer hunting out to a maximum effective range of 300 yards (270 m).

Overview

The .400 Legend is suitable for use in AR-15 type semiautomatic rifles.[1]

History

On April 14, 2023, Winchester Ammunition announced the .400 Legend. The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI), the U.S. firearms and ammunition industry's technical standards-setting organization, announced the acceptance of the new cartridge and chamber standard on January 15, 2023.[2]

The .400 Legend was preceded by the Winchester Model 1910 .401 Winchester Self-Loading cartridge, and in 2014 by the .400 AR[3] wildcat cartridge designed for the AR-15–style rifle.

Usage

The .400 Legend cartridge is engineered for deer hunters requiring a modern straight-walled cartridge that is more powerful and has greater effective range than the .350 Legend.

State legislation

.400 Legend also addresses a rapidly growing market segment known as "straight-wall-cartridge-compliant" deer-hunting states. A growing number of states that previously restricted deer hunting to limited-range slug guns or muzzleloading firearms are now allowing rifles chambered in straight-walled centerfire cartridges.

The .400 Legend was designed for deer hunting in states that have specific regulations requiring straight-walled cartridges for use on deer, such as Ohio, Iowa, Indiana public land, and the Southern Lower Peninsula region of Michigan.[4] Illinois also allows straight-walled cartridges if used with a pistol or a single-shot rifle. The pistol must be a centerfire revolver or centerfire single-shot handgun of .30 inches (7.6 mm) caliber or larger with a minimum barrel length of 4 inches (100 mm) inches. Single-shot rifles in those specified calibers became legal on January 1, 2023.

Ohio's Deer Hunting Regulations allow the use of a straight-walled rifle cartridge with a minimum caliber of .357 inches (9.1 mm).
