....around seems to truly come around. Reading parts of a book "Guns of the FBI" in which the author (retired special agent) covers the revolvers and then most recently the autos. In the heyday of the revolver, the "FBI Load" which is a 158 grain lead hollow point semi wad cutter bullet, performed quite well. This load was also sometimes called the "Chicago Load" or the "St. Louis Load,." After the FBI tried the 10mm and then the .40 S&W, it returned to the 9 mm in Glocks. The load basically chosen is a subsonic 147 grain hollow point. And with that I smiled since the 9mm load really duplicates what the .38 load used to be. The decision to return to the 9mm was its ease of handling and also that after studies, it was concluded that actual real terminal ballistics in handgun cartridges varies very little be they magnums, big bores or mid bores. Placement is the key. Also hit rates usually are around 30 percent or less in gun battles. So, now the FBI has what is basically a .38 that holds something like 17 or 15 rounds instead of the usual 6 in revolvers.
