Hornady redesigned the 200 gr SST for 2009. This is what the new catalog states: a projectile that penetrates better, retains more weight, and expands more agressively. It does not mention anything about how the construction has changed only that it has the Flex Tip Technology. This should stir things up again as most members here have either a love or hate relationship with these bullets. I love their accuracy, but am not overly pleased with their perfomance on deer.
