I have several examples of the Cabelas Blue Ridge...which I believe is the same rifle that you are talking about in this thread.
I have a carbine in .54 calibre. In the full length rifle I have a pair, one is a .50 calibre and the other is a nice little a .32 calibre. The .54 shot like a dream from day one...Once I developed a load and sighted it in; from a rest I can keep 5 shots on a paper plate at 100 yards. For me, shooting with open sights...I'm happy with that. Put a scope on it, like you are suggesting, and I would expect those groups to just get smaller.
The other two guns (.50 & .32 calibres) just seemed to give me fits. They never grouped as well I had wished that they would. The worst was the little .32 calibre, and I know that the little pea shooters can be finicky, but this was a little too finicky for me. I have torn ptches and 4"-6" groups at 50 yards with both guns. Then one day I just had had enough and threw caution to the wind. I got some valve grinding compound and proceeded to lapp the barrels...20 strokes in each one. The next time at the range and no more torn patches; I had nice tight groups. With both they now shoot nice little clovers.
