Thank you for the thoughtful reply. I do still disagree though.

Also look at the luckygunner HST 147gr +P. Amazing. The 9mm HST outperforms many of the 10mm commercial loads for expansion AND penetration. Actually, all of them but two.

Underwood/BB load Speer uni-core bonded bullet, not current Gold Dot or Gold Dot G2. HST outperforms current Gold Dot loads from Vista for expansion and penetration. HST changed the game when it came out. Bigger expansion, deeper, less FPS.

You have to say that energy changed the outcome of being hit. An HST 9mm is going to kill in the right place. Period. The additional FPS of a 10mm isn't going to change anything. Ballistically, the 9mm HST got the bullet there bigger and deeper.

So yeah, the extra lbs umph does nothing for the 10mm performing better.
