Somebody needs to remind the FBI that the "modern bullet technology" they are referring to also applies to .357, .40, and .45 bullets. They are all improved with "todays modern ammo".

This is yet another example of a government agency not being good stewards of taxpayer dollars. Last I checked, FBI experimentation with the 10mm, based upon 9mm failures in shootings, led to development of the 40 S&W. I predict they will switch to 9mm, then determine they need a larger caliber or more powerful cartridge again.

The long game is TO JUSTIFY THE EXISTENCE OF THEIR PERSONNEL ASSIGNED TO THEIR FIREARMS UNIT ON A FULL TIME BASIS. This nonsense is never ending within the federal government.

Just my .02.
