Custom Thompson Center Muzzleloader Barrel

Thompson Center Encore Contender Black Powder Muzzleloader Barrels

Thompson Center custom muzzleloader barrels are now available built by MGM! We’re building on our years of custom gun barrel building experience on the incredible Thompson Center platform by offering a brand new muzzleloader gun barrel. These custom TC muzzleloader barrels will benefit from using one of the top gun barrel platforms available today.

Every single detail of this muzzleloader has been designed from the ground up, to offer you the most premier muzzleloader platform of any out there. It is more robust and accurate that any other on the market today, and we don’t say that lightly.

On top of the new barrels, we’re going to be offering a new muzzle brake that we designed with sabot shooting, loose powder muzzle loading, and after-shot sight picture in mind: the “Smoke Brake”. This will help from not being able to see impacts and reducing recoil, all while not damaging sabots as they exit the muzzle.

Our breech opens 40% more, which allows for hassle-free extractor removal, granting quick access to the breech plug when cleaning.

In this video, 87 grains by weight was used (roughly 120-125 by Volume). Bullets used are .451″ sized to .4505″ but this may vary. Every bore can be slightly different. ALLWAYS use a witness line on your ramrod to avoid double loading.

Breech Plug – Thompson Center 45 Cal Muzzleloader

Our breech opens 40% more, which means the T15 screw holding the extractor in can be spun out, and gives plenty of room for a 3/8″ socket to wrench out the platform specific breech plug. These breech plugs are conventional 360 degree threaded with 9/16″ – 24 threads, and come with tungsten carbide bushing. Why not go with steel for your flash hole? Carbide will not wear out under normal use with 209 primers and black powder or suitable substitutes.

Our plugs are conventional 360 degree threaded with 9/16"-24 threads and a maximum diameter of .625", which means they are optimized for both of the T/C’s
This breech plug comes standard with a tungsten carbide bushing. The tungsten carbide has greatly improved wear resistance from heat and pressure. This means the 0.030” flash hole through the bushing (which is the optimal orifice size for BH209) stays the same shot after shot
These plugs are manufactured to very tight tolerances to allow interchangeability between plugs and maintaining perfect headspace
We headspace these plugs using Federal 209A primers, which is proven time and time again to be the standard for precise and reliable black powder ignition

Forend – Thompson Center 45 Cal Muzzleloader

One of our main focuses over the years has been to keep the interchangeability between the MGM brand and T/C brand simple and fluid. These new muzzleloader barrels will be no different. The Encore muzzleloader barrels will drop into standard T/C muzzleloader forends with the use of our custom forend adapters included in the purchase price of your barrel.

Redesigned MGM Muzzleloader Ram Rod & Jag

The ram rod is custom built for the above-mentioned lengths, model and caliber.

Our ram rods are solid aluminum with a fine polished finish, then anodized to give the attractive offset and protective layer. Both ends are tapped to #10-32, which will allow use of aftermarket handles, jags, and pullers. Our jag is interchangeable with the Spin Jag and features 18-8 SS stud to prevent breakage. The jags are made to be the same length as aftermarket options to allow for seamless transition between the many options.

Ramrods are 700 Fine belt polished before Type III anodizing to prevent bore damage and longevity
Both ends of ramrod are beveled and tapped #10-32 for versatility of utilizing appropriate accessories like: jags, handles, and bullet pullers
Jag male threads are a SS stud which will prevent bending or breakage
Jag nose is optimized for standard commercially available bullets
Jags are blue Loctite installed prior to shipment

Regarding Smokeless Muzzleloader Barrels

We do not make smokeless rated barrels here. If you want an Encore barrel that is rated for smokeless powder, please contact either of these smokeless pros for your needs:

Hank’s Precision Gun Parts

Hanks Precision Gun Parts

Arrowhead Rifles

Arrowhead Rifles

Either of these companies stock barrels that originated here and they’ve added their own ignition systems or other specs to make them safe to use with their recommended loads of smokeless powder. Our barrels are intended for 85-87 grains of BH209 and ignited by a Fed 209A primer. For more information watch the YouTube video (link) above or read the full write-up here (link).

MGM Muzzleloader Creation Timeline

Early 2018
Work began on the new muzzleloader
Breech Plug
Realized we had to set a new pace in breech plug design
Durable, yet small enough for the G2

Breech Plug
Extractor

Had to overcome the "forend removal" in the cleaning process
Getting the barrels to open farther means hassle-free extractor and plug removal
Ramrods
Had to solve the ramrod sandpaper issue
After creating the ramrods we found them eating into the thimble, so we used 700 fine belt polished to solve this

Ramrods
Stand-Offs/Forend Adapters

Next we had to "fix" the weakest link on factory muzzle loaders
We have the strongest forend adapter possible
