If your rifle shoots Federal blue box well, I don't see any need for a different bullet for deer sized game. Sierra Game Kings perform well as do Rem Core Lokts. The GK and CLare not bondedso if you have a very fast cartridge you may want to look at a bonded bullet to reduce meat loss. I have not shot Fed Fusion, but from what I have heard the bullet performs well and iscapableof instant kills. Some have said Federal has recentlygone to a dirtier powder for the Fusion loads. I can't comment on the SST.
