- #A 145 gr 10mm would be more analogous to a 185 gr .45 than the 170-180

- I have 25 distinct samples of commercial .40S&W ammo, including bullet
- masses from something like 85gr through 180gr, velocities from subsonic
- through 1400fps, designs varying from FMJ and SWC through exotic hollow-
- point plus duplex and Glaser Safety Slug. I think the reason for the
- prevalence of 180gr in this caliber (also in 10mm) is that that is what
- the federal specifications are and thus what a large portion of the law
- enforcement market demands. I like to think that most commercial ammo
- packages are the result of appropriate R&D, similar to a lot of the work
- we do at the Proving Ground, but I don't know that to be the case except
- for isolated instances.
