Just taking a blind shot in the dark on this one, but it may have something to do with the fact that the Barnes 115 gr. copper bullet is much longer than your standard 115 gr. bullet, and as a result, the volume available for the powder is much less than a normal 115 gr. bullet. I've captured one of these rounds in a line of water jugs and it expanded to a decent size and had good penetration.
