Now I have to tell you, I have always been a 'short/light' rifle kind of guy. I bought a BC 45-70 this summer and have been having a ball with it. I thought it would be muzzle heavy and awkward but it is not. It seems to balance very well and feels light. Of course none of the NEF guns are very heavy anyway. Because of my age, I much prefer scopes anymore, but I thought I would try the sights that came on the gun. I tried two upper level one loads, sat down at the bench, and my first two shots were touching at 100 yds! Both loads shot about 2 1/2" at that distance with the receiver sights and I'm sure would do much better with a scope. I'm happy and impressed. I like the looks of the BC better than the standard model my friend just bought, but he likes his too. Buy the one you prefer and don't worry about any accuracy differences. Individual guns vary more than what the barrel difference would make. Yes, each barrel can be put on the other frame, but the factory is supposed to fit them. 44 Man
