You know that moment when you’re on the stand, the cold’s creeping in, and you’re fumbling with a breech plug that’s caked with carbon? Been there. That’s why when I first got my hands on the Thompson Center Encore Endeavor Speed Breech Xt Plug, I was looking for one thing: a reliable, easy-to-clean solution that wouldn’t have me playing surgeon in the field. Let me tell you what I found after a season with it.
The Thompson Center Encore Endeavor Speed Breech Xt Plug is a precision-engineered replacement breech plug designed specifically for Thompson Center Encore and Endeavor muzzleloader barrels. Its core purpose is to provide faster, more reliable ignition with a design that simplifies cleaning and maintenance, directly addressing common pain points for muzzleloader hunters. Look, if you’re tired of inconsistent ignition or spending half your cleaning time picking at a tiny flash channel, this part has your name on it.
So, what makes it different? The “Speed Breech” name isn’t just marketing. The design incorporates an optimized flash channel that directs the primer’s flame more efficiently to the powder charge. I’ve put about 40 rounds of Blackhorn 209 through mine, and the difference in ignition consistency is noticeable, especially on damp mornings. That reliability is what you’re paying for.
The real win, though, is in the maintenance. The Xt Plug features a user-removable, self-centering vent liner. After a few shots, you can simply unscrew this small liner—no special tools needed—to clear the critical flash hole. This is a no gunsmithing required operation that turns a 15-minute chore into a 30-second wipe-down. It keeps the main body of the plug cleaner for longer, too. The plug itself is machined from heat-treated, stainless steel, so corrosion isn’t something you’ll lose sleep over.
Here’s the thing—compatibility is key. This plug is a direct-fit component for Thompson Center Encore and Endeavor muzzleloader barrels. It’s also designed to work with common 209 shotshell primers and is optimized for use with modern propellants like Blackhorn 209. You won’t be modifying your firearm or guessing if it fits; it’s a straightforward swap.

Pros: Dramatically simplifies cleaning with the removable vent liner. Provides excellent, consistent ignition. Built from durable, corrosion-resistant materials. It’s a direct replacement that fits out of the box. For the price of $56.48, it’s a solid upgrade that pays off in saved time and confidence.
Cons: It’s only for T/C Encore and Endeavor owners, so it’s not a universal part. You still need to perform basic maintenance—this just makes it far easier. The initial cost is higher than a standard plug, but the long-term value is there.
This part is for the Missouri muzzleloader hunter who values every second of their time in the woods. If you own a T/C Encore or Endeavor and are frustrated by tedious cleaning or have experienced a misfire due to a clogged channel, this plug is your solution. It’s also a smart buy for anyone who uses Blackhorn 209 regularly and wants to maximize its performance and ease of use.

Frequently Asked Questions
Q: Is this plug compatible with my Thompson Center Pro Hunter muzzleloader barrel?
A: No, it is not. The Thompson Center Encore Endeavor Speed Breech Xt Plug is specifically threaded for the Encore and Endeavor series muzzleloader barrels. The Pro Hunter uses a different thread pattern, so you’ll need to source the plug designed for that model.
Q: Do I need any special tools to install or maintain it?
A: Installation requires a standard breech plug wrench that fits your Encore/Endeavor frame. For routine maintenance of the vent liner, no special tools are needed—it’s designed to be removed by hand after the plug has cooled, making field cleaning a real possibility.
Q: Can I use this with Pyrodex or Triple Seven pellets, or is it only for loose powder?
A: You can absolutely use it with pelletized propellants like Pyrodex or Triple Seven. The efficient flash channel design improves ignition across various black powder substitutes. That said, its performance with loose powders like Blackhorn 209 is particularly impressive due to the precise flame channeling.
