You see, it matters how much gunpowder is required to achieve the necessary velocity, because gunpowder weight affects recoil force. 165-grain vs 180-grain .40 S&W ammo? The mass is the mass of the bullet. Features such as the no-clog hollow point bullet and a design and powder load specifically for use in a full size handgun contributed to the decision as well as consistent performance in testing. Within each caliber, you will notice that there are certain bullet weights you see more often than others. The science behind long range rifle shooting is vast and confusing, but there are many precision shooters out there who can offer guidance and education on the topic. While I've used 115 (lots) and 147 gr bullets in my 9mms I have a reloaded some thousands 124/125 gr. make perfect sense for plinking. They are both stout.
