The Thompson Center Encore ProHunter Katahdin rifle barrel in .400 Legend gives you a fast, efficient way to add a modern straight-wall hunting caliber to your Encore platform. This 20-inch blued barrel is threaded at 11/16-24, letting you run a suppressor or muzzle brake without permanent modification. If you're already invested in an Encore rifle or shotgun platform, swapping to the .400 Legend opens up a dedicated rifle option for deer and similar-sized game in states with straight-wall cartridge hunting seasons.
The .400 Legend is purpose-built for lever-action and modern straight-wall rifles, offering enough velocity and energy for effective hunting while keeping recoil manageable. The 20-inch barrel length is compact enough for dense timber or brush hunting, yet long enough to make efficient use of the cartridge's ballistics. The threaded muzzle gives you real flexibility: run it stock, thread on a brake to manage what little recoil there is, or add a suppressor for hearing-safe shooting at the range or in the field.
This is the core appeal of the Encore platform—modularity. Rather than owning multiple rifles, you own one action and swap barrels to match the season, the game, and the regulations where you hunt. Thompson Center has built their reputation on this kind of versatility, and this Katahdin barrel is a straightforward way to add .400 Legend capability to an existing Encore setup.
