What do either of those two things have to do with the other?
I thought the whole longer = better myth had been busted ages ago.
Shorter barrels carry better, allow you to run a heavier/stiffer contour without a major weight penalty, and in practical terms with modern bullets and powders give up very little in outright performance when we are talking about big game hunting in the field... on the bench with all other variables controlled for? Maybe* a long barrel allows for slightly higher velocity which increases margin for error related to wind, but that's stretching it.
