I was able to stack 3 400gr factory loaded Federal Cape Shok right on top of each other at 100 yrds. That's no BS either, center to center was 5/8", I could not believe it, neither could my business partner. As far as the barrel length, you would have to be in some pretty thick shit for that extra 2" of barrel to make a difference, in which case I think the scope, the sling and other things would be more of a hinderance.
