You quite obviously don't get science then, RVD.

When you decrease an objects mass, it allows it to be accelerated to higher speeds, due to the theory of relativity. Speed is the most important factor in determining an object's energy, since KE=(1/2)m(v^2), which allows far more energy to impact a target.

You're using a very narrow definition of "supersonic" as well, since at its most basic definition, all it means is that it's going faster than the speed of sound. You're assuming that modern-day definitions for "supersonic", "hypersonic", etc. still apply in the Mass Effect universe. This is an assumption you can not make.

And as for this "grain of sand" bullcrap - provide sources, or I'm going to assume that the guns are shooting normal-sized bullets. Seriously, claiming that websites and blogs state it i bullshit. Provide CANON SOURCES that say this.
