...1. Accuracy: The longer a bullet is in relation to its diameter, the more accurate it normally is. It is a rare .44 Magnum sixgun that does not shoot 300- to 320-grain bullets more accurately than it does 240- to 250 grain bullets. ...
I'm not sure I agree with the longer is more accurate part. A heavier bullet will buck wind better for sure. Other then that I can't see what the advantage would be. Someone care to enlighten me here?
I think the "longer bullets are inherently more accurate" stuff comes from the basic idea that longer bullets have more surface contact with the rifling in the barrel, or have three driving bands instead of two, thereby imparting a bit more stability as the slug travels down the barrel. Another idea stems from the connection between bullet weight and the rifling rate for a given caliber. This latter is the heart of benchrest rifle accuracy, but it applies to pistols, too. There certainly are more than enough theories about revolver accuracy and certain revolver/bullet/powder combinations to keep hobbyists busy for years. At this point in my shooting, if I can keep 90% of my .44 magnum rounds on a 8 inch target center offhand at 25 yards, I'm happy.
Although I like long heavy bullets, they are generally less accurate than shorter, lighter bullets. Just the opposite of what he says.
I also like large diameter heavy bullets loaded lightly. Sometimes the rifling twist isn't fast enough for the heavy bullets tho.
