Looking at his rifle picture, I don't have that large of a spur on the hammer which strikes the firing pin plate, and the barrel is shorter on the Yukon I believe. Other then they all the parts trade off.

Is that a stainless steel or nickel barrel on that Yukon? But then if it will shoot like that, who cares..

I watched a hunting show on TV a while back. There was a woman in a tree stand hunting black bear over a bait and she was shooting a Yukon or Genesis. She was shooting 100 grains of Pyrodex RS and I believe it was a Barnes bullet. She really knocked the snot out of that Black Bear with that set up.
