257Robt,
I think you and I have sorta had this discussion before, or commented about it in different posts, where we both noticed that on the 760's, 7600's, 742's, 7400's, the carbine barrels seemed thicker than the standard 22 inch barrels. Not only is a shorter barrel inherently stiffer to begin with, but with the carbine barrels being thicker, I think, helps accuracy a lot. I do feel the carbines are more accurate, due to the short stiff barrel. My 760 is a carbine, 30-06, with a low mounted 1.5X5 Leupold Vari XIII, I've shot more than a few whitetails with it, and you couldn't get me to part with it, and it groups bullets just as tightly as any quality bolt action.
Sincerely,
Garry
