CVA Paramount T-1 Variflame Breech Plug for 40 Caliber Muzzleloaders
- Caliber-Gauge:

- Model:
- Paramount
The CVA Paramount T-1 Variflame breech plug for .40 caliber muzzleloaders is a drop-in replacement designed to handle the demands of modern in-line rifles running heavy charges. If you shoot a CVA Paramount and want reliable ignition without constant breech cleaning between shots, this upgrade solves a real problem: the original .40 cal plugs struggled under super-magnum loads, but the new tungsten-core design holds up to sustained pressure and delivers the durability you need for a full day at the range or in the field.
The T-1 Variflame uses large rifle primers for ignition and features a patented design that keeps the flash hole clear of powder residue—even when you're running fine loose powder. That means fewer cleaning interruptions and more consistent shot-to-shot performance. Whether you prefer loose or pelletized propellant, this breech plug performs the same way, so you can experiment with loads without worrying about ignition drift.
This is a plug-and-play fit for all CVA Paramount muzzleloader rifles chambered in .40 caliber. The tungsten insert isn't just marketing—it's a direct response to shooter feedback about durability under the higher pressures these modern in-liners can safely produce. If you've experienced flyer groups or rough extraction from a worn breech plug, the T-1 Variflame is a straightforward fix that pays dividends in accuracy and reliability.

Frequently Asked Questions
Will this breech plug fit my CVA Paramount muzzleloader?
Yes, the T-1 Variflame is designed as a direct replacement for all CVA Paramount rifles in .40 caliber. It's a straightforward swap.
What primers does this breech plug use?
The T-1 Variflame is specifically designed for large rifle primers, which it accepts via the patented Variflame adapter system.
Can I use this breech plug with both loose powder and pellets?
Yes. The T-1 Variflame works reliably with both loose and pelletized propellants, so you can load however you prefer.
Why does the tungsten insert matter?
The original .40 caliber breech plugs experienced durability issues under the high pressures generated by super-magnum loads in Paramount rifles. The tungsten core is harder and more heat-resistant, ensuring the plug holds up to repeated heavy shots and maintains its integrity over time.
