Guns are not just about how much energy the projectile is moving with.
To actually make use of that energy, the projectile has to be able to transfer that energy to the target.
That's why people use hollow point rounds in weapons for use against meatbags.
Hollow point rounds basically go splat, transferring all of its energy into the target and shredding it from the inside.
An armour piercing round with the same amount of energy would just pierce the flesh and go out the other side, resulting in minimal damage.
A projectile the size of a grain of sand would have tremendous armour piercing capability, but it'd be terrible at causing any actual damage.
In fact, after a threshold depending on the size of the projectile, it'd actually start causing less damage with more energy, because it'd start piercing flesh so easily that very little energy is actually transmitted.
You'd just get perforated and highly uncomfortable rather than dead.
Except that anyone with basic knowledge of ME's lore knows that the sand-sized bullets fired from firearms in the game squash upon contact, transferring its energy straight into the target.
