    I don't own or shoot a Knight Disc Rifle but I came across this new style breech plug design for one on www.knightrifles.com and thought that it sounded innovative, so I'm bringing it to your attention.
    This breech plug is called the Knight Power Stem. It's designed to ignite the loaded powder at the top of the charge 1st before traveling down to the base of the charge rather than the other way around as most conventional breech plug designs do.
    I couldn't relocate the initial article that I read that stated how much extra velocity is attained from the use of this breech plug, but it's also supposed to help promote better accuracy and burn the powder more cleanly.
    Also, it's designed to be used with loose powder only and requires at least 70 grains of powder loaded into the barrel to have the primer flame reach the top of the powder charge and ignite it properly.

    One gunsmithing expert stated that this is an old innovation that was even tried out in cartridges some 50 years ago. It's interesting how old ideas have a way of resurfacing, especially if they have any merit. :D
