I ran the original X for a while, decent accuracy but good on game. I've done the TSX thing for a while and they are a great bullet, just expensive and not that great of BC. Now I'm running Bergers, AccuBonds, and those cheap PowerMax Bonded (which are proven to be an excellent cheap round)...

Never shot SST's, but had a friend shoot them for a while. Great accuracy, but horrible results on deer. Didn't penetrate at all! One blew up on the front shoulder, the other blew up on the neck, neither penetrated at all! Out of a 30-06 so not a high velocity round either...this was coming from him, I never saw the deer, but have no reason not to believe him.
