    Inquiring minds want to know why the .40SW rounds are flat? I see some if not all .380's are the same? :confused:

    Here's the info you need to answer all your questions.

    Rounds of the same caliber but with different-shaped meplats sometimes cannot be loaded into the same firearm.

    The meplat plays an important role in the loading of weapons whose ammunition is guided into the chamber by a mechanism (e.g., auto-loading, lever action or bolt action).

    Meplats are often used to increase the bullet's wounding ability.

    Coincidentally, the shape of the nose of an axisymmetric projectile that gives it the least possible aerodynamic drag at hypersonic speeds always has a meplat, the diameter of which depends on the length of the nose.


    So...max speed, lowest drag, better wounding ability, better feeding...Flat point.

    Other older bullets don't have flats because they were designed earlier, when pointy made sense.

    That's where I got it, but everyone seemed to be ignoring it, so I put it here so they could read it.;)
