I have found, for the most part, that my most accurate loads are usually the loads that are close to, or at max. At any rate, since I am never going to shoot a rifle enough to burn the barrel out, I usually choose to reload cartridges that will go as fast as they can without being on the hot side. I won't give up accuracy for speed, but if I can have both, why not. I figure that's a no brainer.
