i've used the 250 grain Hornady SST along with the 250 grain TC Shockwave for about 8
years: They have killed a lot of deer and wild hogs for me.
The SST has a soft rubbery nose; the Shockwave has a hard plastic nose, otherwise they are the same bullet. i've tried to determine the difference in effect on hogs and deer. Still do not have a good feeling for that. However, judging from about six long shots on hogs and deer, i believe the soft plastic nose of the SST allows for better expansion at long range.
