I'm very happy to hear Your Dad's Ruger is very accurate. Nothing better then a accurate reliable gun.
Has anyone ever wondered why T/C made two break open Muzzleloaders? The reason was the Encore/Pro-Hunter/Endeavor design was horrible. They also new they could not change it because of all the differnet barrels offered. All you need to do is ask

I have always said the Encore was a great ML. But it needed to be tweeked first. Working up a load has nothing to do with it. Make the gun right, finding a load is easy.
That is why the Triumph was made. And the Triumph is designed alot better and does not need tweeked out of the box. If you talk to the right people at T/C, they will tell you not to buy an Encore over a Triumph if you want a ML only. It's obvious to anyone that own both.
The Triumph is a tack driver no doubt. I cant honestly say how long it will stay that way. It sure will last alot longer then an Encore. The bolt action ML has less moving parts and obviously locked up tighter then a break action. Which in the long run means more accurate over time.
Like someone mentioned above, for most people it doesn't matter. They wont shoot enough to see a difference. And the break actions are shorter and lighter and alot easier to carry and carry on a quad. That's a big reason why they are so popular.
I actually hope Knight makes a high quality break open. I think the demand is more for them then bolt action guns today. But if i could only own one, it would be a bolt action.
