My partner zapped a bull in Colorado yesterday. 140SST started out at just over 2950fps using V100 in his Savage. Distance was 357yds at a very steep downhill angle. Hit the top of the shoulder and destroyed the off-shoulder. Boolit was an inch shy of exiting. As they were cutting up the elk and found the boolit, the core fell out of the jacket. No big deal...the boolit did its job.
