I found a empty box of these,the box says Dynamics Research Technologies .I found a bunch of 40 S&W brass laying around so I don't know which h/s they were the three most h/s that I found were r-p,S&B(with some sort of symbol stamped next to it),and Hornady.I am pretty sure it's the S&B's(Selliar & Bellot ?).Never saw these before,must have a massive velocity number.The box says "on impact the core turns to powder in its original composition". Can you say explosive fragmentation.

It may not be as hot as you think. While the bullet may be lighter (frangable) the load (powder may be too). No mater what you still have to stay under 35,000 psi for the 40 S&W.
