350 Legend and 400 Legend — Welcome to the Hall of Legends
The Hall of Legends brings 350 Legend and 400 Legend together around the places hunters know well: wooded ridges, narrow trails, field edges, and the cabin where another season begins. These straight-wall cartridges offer two distinct options in the Chattahoochee Munitions CM15 platform, supported by caliber-specific magazines and detailed guides that help you understand the complete rifle-and-ammunition combination.
Choosing a hunting rifle starts with your ground and the shots it presents. Close timber, mixed terrain, and longer openings place different demands on ammunition and equipment. Here, you can explore both cartridges, compare them with established hunting calibers, and select a CM15 configuration suited to your priorities.
350 Legend CM15 — An 18-Inch Straight-Wall Hunting Rifle
Our 350 Legend CM15 features an 18-inch barrel, 1:16 twist, and carbine-length gas system. Available finishes include Black Tungsten, FDE Metallic, and Cobalt Kinetics Green, giving you three versions of the same core rifle configuration.
The 350 Legend Guide explains the cartridge’s design, factory ballistics, ammunition choices, and role in the CM15. It provides a foundation for evaluating hunting loads and understanding how barrel length, bullet construction, and intended use affect the overall combination. For additional manufacturer information, explore Winchester’s 350 Legend overview.
For a familiar reference point, read our 350 Legend vs 30-30 comparison. The article examines specific factory loads and the differences between these two deer-hunting cartridges, helping you look beyond broad claims about which caliber is more powerful.
400 Legend CM15 — A 16-Inch Straight-Wall Rifle Option
Our 400 Legend CM15 features a 16-inch barrel, 1:16 twist, and midlength gas system. It is offered in the same Black Tungsten, FDE Metallic, and Cobalt Kinetics Green finishes, providing a consistent selection across the Hall of Legends.
The 400 Legend Guide covers the cartridge’s background, hunting ammunition, published ballistics, and CM15 configuration. Use it to understand the cartridge before narrowing your choice to a particular rifle or load. Winchester’s introduction of the 400 Legend provides additional context on its development and intended hunting applications.
Our 400 Legend vs 44 Magnum comparison places it alongside an established lever-action hunting caliber. Rifle-oriented ammunition data, bullet construction, trajectory considerations, and platform differences explain where each combination fits.
Dedicated Magazines for 350 Legend and 400 Legend
Caliber-specific magazines are an important part of both CM15 configurations. The 10-round 350 Legend magazine and 10-round 400 Legend magazine provide dedicated feeding geometry for their respective cartridges.
Both are DURAMAG stainless-steel magazines. Select the magazine that matches your rifle’s chambering, and confirm reliable function with your chosen ammunition before hunting season.
A Familiar Platform for Straight-Wall Hunting
The CM15 brings AR15-pattern operation and detachable magazines to these hunting cartridges. Across both caliber families, the three finish options let you choose the appearance you prefer while retaining the specified barrel, twist, and gas-system configuration for that caliber.
For suppressed use, Chattahoochee Munitions recommends flow-through suppressors for both Legend CM15 configurations. Suppressor selection should account for cartridge suitability and compatibility with the rifle and mounting system.
Where hunting regulations specify straight-wall cartridges, check the current requirements for your location and season. Permitted firearms, cartridge dimensions, and magazine capacity can affect your equipment choices.
