  • Modern 9mm vs. 40 Data

    I am NOT trying to stir up another caliber wars debate. Shoot what you can hit with and are most comfortable with.

    Having said that, does anyone have any modern ballistic data regarding 9mm vs 40 for expansion, penetration, etc? I know that the 40 has more stopping power, but by what kind of margin over a good +P round like a HST?

    Ammo has come a long way since 1986 and was wondering if the .40 is a moot point now if a solid 9mm +P can perform the same but with greater control, less recoil, and higher capacity.

    Factual data only please, not personal opinion or preference.
    Shot placement > caliber. Using a .45ACP means nothing if you can't hit your target. Practice, train, and do it all over again...and again...and again.

    Go to the federal ammunition law enforcement website and click on the ballastic tables. There you can see the FBI test results for the HST and other major brand hollowpoint's in 9, 40 and 45.

      Winchester's site also has a fantastic table where you can select various rounds to see their energy and expansion characteristics and compare..
      Seriously, the only reason I wanted to be a cop was so I could post anywhere on this forum.

                errrr Ya....

                I say,

                Even if you know most, 99.9% of the delta variables, One cannot conclude a solid definitive solution or answer concerning this particular inquriry...

                We have factual irrefutable mathematical solutions that Euclid Failed contemplating much simpler inquiries, born from later complex truths.

                This hypothesis started as a complete disaster and failure due to it qualitative nature and lack of definitive component(s)...

                I suggest that you start with known agreements and work from there.

                And the best of luck.. in your journey, in and around the laws of nature..

                    Whichever round performs best in FMJ hardball configuration is what you should shoot. Because when whatever super dooper exploding tip depleted uranium razor tip flower petal with silver tips and piranha teeth round fails to perform as advertised, it falls to the lowest common denominator which is (K.E.=1/2 x m x v 2)

                        Too many variables. Barrel length is one. your definition of expansion, penetration, etc is going to depend on target. Is it ballistic gelatin? Heavily clothed individual? Windshield glass? Bony part of body like the head? Gypsum board?

                        You might find a +P+ round that performs similarly to a 40S&W round in ballistic gelatin out of a 4" barrel. Change the barrel to 5" and everything will be different.
