The SST is pretty much the hornady "version" of the ballistic tip. It is primarly for deer sized game. Im loading up with 165 grain SST's in my 06 for this upcoming deer season. They are shooting nice groups out of my gun. The Interbond is pretty much the hornady "version" of the accubond. It is a bonded bullet with a polymer tip and suitible for game such as elk and moose.
