I came across some of this stuff in the gun store the other day while picking up some Federal HST's for my carry gun. I took a good look at them and the seemed gimmicky. A 60gr .40 that travels at almost 2000fps? No thanks. That's just too far outside of conventional thinking. And they feel insubstantial when holding them. So I bought the HST's and went home. But my curiosity got the best of me and I watched the video. Now I'm thinking that I might change my carry ammo for only the second time in 20 years.
