Hornady told me the only difference between the FTX and the SST is the composition of the tip. One is more rubber-like and the other plastic.

I'm not sure the Shockwaves are the same bullet.

I can say, between me and my friend, the Shockwaves are not close to as accurate as the FTX/SST's have proven.

I agree, the FTX/SST's are crazy accurate, we're getting consistant MOA groups with them and 100 gr BH209 OR 100 GR Shockey Gold.
