I have had almost all the muzzle loaders TC has made and it was no trouble to me to get any of them to shoot really well, I have had a number of Knights and can say the same for them.
If i had to choose one out of all of them it would be the Triumph because of two things, its shear consistency and its like for a heavy load. It does best with 110 and 120 gr loads with most bullets.
Yet while it likes fewer loads the Omega is an excellent gun liking a bit lighter loads 90 and 100 as a rule with a laminated wood stock and the 25 case conversion it stands among the very best.
