The Thompson/Center ProHunter XT Katahdin barrel (part 8290R) takes your existing Encore ProHunter frame and drops a .50 caliber, 209-primer muzzleloader right into your hands. The break-open Encore platform was built around this exact idea: pull two forend screws and the hinge pin, swap barrels, and you've got a whole different gun. If you already own a centerfire ProHunter and want to chase a black powder season, this is one of the cleaner ways to do it without buying a second rifle.
At 20 inches, the Katahdin runs shorter than the standard 26 and 28 inch muzzleloader barrels, which makes it a natural fit for treestands, ground blinds, and tight timber where a long tube gets in the way. It's cut from stainless steel with T/C's signature fluting, so you get corrosion resistance and a lighter carry weight without giving up the stiffness that keeps groups tight. The bore is the same quality glass you expect from Thompson/Center, and plenty of owners report golf-ball accuracy at close and mid range once they find the load their barrel likes.
Ignition runs off a standard 209 shotshell primer, and the barrel uses T/C's hand-removable Speed Breech plug. The design threads out with just a few turns and resists the powder crud that can seize up conventional breech plugs, so teardown and cleanup at the end of a hunt stay quick. It comes set up with sights from the factory, including a Williams-style adjustable rear peep and a fiber optic front bead, and the barrel is drilled and tapped if you'd rather mount a scope.
This current fluted version uses a standard ProHunter muzzleloader forend rather than the old-style Katahdin forend from years back. If you're running a 209×50 ProHunter setup already, your muzzleloader forend should drop right on. Blackhorn 209, Triple Seven, and Pyrodex all have a following in these barrels, so it's worth working up a load with a couple sabot and bullet combos to see what shoots best out of the shorter tube.
Yes, this barrel is built for the Thompson/Center Encore ProHunter break-open frame and swaps on by removing the forend screws and hinge pin. This current fluted stainless version uses the standard ProHunter muzzleloader forend rather than the older special Katahdin forend from earlier blued models. If you already run a 209×50 muzzleloader forend, it should mate right up.
It ships ready to hunt with iron sights, including an adjustable rear peep and a fiber optic front bead. The barrel is also drilled and tapped, so you can add a scope base and rings if you'd rather glass your target. Either setup works well out to reasonable muzzleloader distances.
The shorter barrel handles the popular options well, and Blackhorn 209, Triple Seven, and Pyrodex all have a strong following among owners. Sabot and bullet combos from Barnes and Hornady are common starting points. Since a 20-inch tube burns powder a little differently than a 26 or 28 inch barrel, plan to test a few loads to find the one your barrel groups tightest.
The 20-inch length makes the whole rifle quicker to shoulder and easier to maneuver in a blind, treestand, or thick timber. It trims weight for long walks in and out while still delivering the accuracy Thompson/Center barrels are known for. For close and mid-range whitetail work, it's a handy, hard-hitting setup.
