the Grand Slam is a pretty dumpy shaped bullet. retained velocity and energy at long range is pretty poor compared to other bullets. if placement is sure, then it will kill obviously, but it's not a very potent number, especially when ranges stretch to a quarter mile.
1200 ft -lbs @ 425 yards for the 130 GS
now a 140 TSX-BT would land with 1550 ft-lbs, and retain 100% of its weight and penetrate very deep.
would be a better bullet for elk in a 270 IMO
