The innovative pivoting ignition system of TC's Omega has revolutionized the black-powder industry. TC's patented pivoting action seals the 209 primer tight, ensuring 100% of the fire from the primer goes into the powder charge. There's no need for a capper or any other priming system, just insert the primer into the primer hole and close the breech. The magnum charge capability, up to 150 grains of black powder or Pyrodex®, sends slugs thundering downrange. Quick-Load Accurizer Muzzle System on the 28" barrel makes loading easy, and 1-in-28" twist stabilizes sabots for tack-driving accuracy. The pivoting action also makes the .50-caliber Omega easy to clean. There's no bolt assembly or breech assembly to clean, and you don't have to disassemble it to remove the breech plug. Tru-Glo® fiber-optic inserts in adjustable all-steel sights. Rifles are available rifle only, rifle with scope, rifle with starter kit, or rifle with scope and starter kit.

I found that on cabelas website. It seems like it was made for sabots and pyrodex. Who knows. All i know is, after seeing all these posts, i wont spend $575 for one. I wont even spend the $375 lowest price on it lol.
