Or, the 10mm (Fbi Special) as it was then known.
Here is the FBI's publication from November 1989 that documented the testing that led to the adoption of the "10mm" by the FBI.
Some interesting observations:
The tested FBI load that was voted overall best performer was 180gr at only 950fps. What are the typical .40SW loads at in 180gr?
- Speer Gold Dot: 1025fps
- Ranger T: 990fps
- Federal HST: 1010fps
- Speer "short barrel": 950fps
Interesting that the Speer short barrel is exactly the same specs as the load the FBI whipped up for the 10mm testing.
Do read all of the report. Especially the part about extra power in the round just giving more recoil and muzzle flash without any increase in ballistic performance.
