It depends on what you mean by better. Velocity and accuracy wise the best full power loads will use the same powders as "standard" barrel length loads.
I had it in my head that a shorter barrel would have a faster powder work most efficiently. I assumed that, because slower powders seem to work better in longer barrels. That's based on my work with pistol-caliber rifles. H110 in 357 Mag and 44 Mag starts to make real sense if you take those chamberings and go from a 7.5" pistol barrel to an 18.5" carbine.
