If a longer bullet is loaded to the same overall length as published data for a shorter bullet, the pressure will be greater. Also, diameter matters. 9mm Luger/Parabellum bullets are generally .355 inches in diameter. Softer bullets can be .356 inches. There are very similar bullets that are .357 inches in diameter that are designed for larger bores such as.38 Special and .357 Magnum that I was told should not be used for 9mm Luger because the pressure would be much greater.
