From the Cabelas site it looks like a 175. Hornady loads a .40 S&W 175 grain Flexlock:http://www.hornady.com/store/40-S-and-W-175-gr-FlexLock-Critical-DUTY/
So perhaps they are loading the same bullet in 10mm now? It would be interesting, and I would think a 175 grain bullet at 1150 would be better than a 165 grain bullet at 1150. Also, there is a difference between Hornady's Critical Duty ammo as compared to their Critical Defense ammo.
Edit: Misunderstood your question....from what I have read, the Critical Duty
ammo has a harder bullet for penetration through barriers, and is designed for law enforcement. The Critical Defense
ammo is designed for personal protection, and is supposed to open up faster with less penetration.
