You'd have to have a pretty long barrel before you start losing velocity. I've heard that it's possible in 22's fired from some of the longer production barrels, but doubt any centerfire is long enough to actually do that.

You may reach a point where gains are so small that it is certainly not worth the longer barrel. Id say somewhere around 16-20 would be as long as I'd want a pistol caliber rifle.
