I have used S&B 173 gr SPCE for two whitetails and a wolf. Range from 80 yds on the wolf and 120 and 230 on the deer. All expanded well and exited. Rifle was my Merkel combo, it is chambered for the rimmed version of the 7x57. I have found many of these bullets behind my range backstop that slipped the core after going through a couple layers of plywood and then hitting the dirt.... but performance on smaller big game seems OK. I did pass up a shot at a 5x5 bull elk while carrying that rifle, I just didn't have enough confidence in the bullet with the shot angle presented.
