I am loading 130 grain Sierra Pro Hunters in my 270 WSM. Sometimes premium bullets don't work well on deer and other medium game as they are usually intended for and made to withstand hitting heavier bones and muscle on bigger game. You may find that the 140 Acccubond which is a pretty heavy bullet for the 270 may niot expand on deer size game. The 130 grain bullet from the 270 has about the same SD as the 168 from the 30 calibers.
