Thompson Center Prohunter Xt Mz Bbl 209 45Cal.45 Caliber

The Thompson Center Prohunter XT muzzleloader barrel in .45 caliber gives you a dedicated 209 shotgun primer ignition system in a 28-inch configuration, purpose-built for hunters who want the flexibility of a modern inline muzzleloader without swapping actions. This is a straight barrel swap for compatible Thompson Center platforms, letting you keep your preferred stock, trigger, and rest-of-rifle investment while gaining a traditional blackpowder hunting tool that's reliable and accurate at field distances.

Thompson Center engineered the Prohunter XT line around proven ignition and barrel design. The 209 primer system offers consistent ignition in wet conditions and real-world hunting situations—no finicky matchlock or flint concerns. The .45 caliber gives you classic muzzleloader ballistics suitable for deer and similar game, and the 28-inch barrel length balances velocity development with handling in timber and thick cover.

Swapping barrels on a Thompson Center platform is straightforward: remove the foregrip pin, rotate the barrel out, and install this one. No gunsmith work required. If you already own a Prohunter XT or compatible Thompson Center inline, this barrel opens a second hunting season—or lets a hunting partner use your rifle with a blackpowder configuration for states and seasons that require it. It's a cost-effective way to diversify your hunting capability without buying an entirely new rifle.
