Is the breech plug for a Thompson center new englander removeable?

The short answer is yes it can. I'm a muzzleloader gunsmith and T/C dealer of 30 years. I can remove it with a special tool, but I wont and neither should you. There is no reason to ever remove a breech plug from any traditional muzzleloader. Removal is not necesary for cleaning and I dont see any other reson to remove one. Of the few I have taken off, some took over a week and a six foot cheater bar to get off. Some just wrung off. T/C used to sell a tool for removing the breech plugs but customers using them were screwsing up the threads and sending them in for warrenty work. After that, about 1980, they started putting them on so tight and with so much industrial locktite, they are almost impossible to remove. Once again, I've never encountered a need or reason to remove one. RamblinMan
