If you had one of each in your hand you could tell the difference. On the carton they came with, there is normally a label that will tell you what they are. If they came with a package deal they are normally 250 grain as that is the most common out there.

Also look at the color of their plastic nose. Yellow is the standard Shockwave and blue is the bonded. If they are red then it is a SST made by Hornady. Same bullet, just a different sabot.
