Ball ammo for .25 ACP is a whopping 1d pi-.
If we're shooting a thug in a cotton shirt that gives 1-6 raw damage which will be cut in half, so 1-3 points of actual damage.
You can buy hollow-point ammo for it, which upgrades the damage type one step, so pi- becomes pi. But it also adds an armor divisor of 0.5 which doubles the DR of actual armor and gives things that aren't armor DR 1.
Now we're shooting through a shirt that has DR 1. So 0-5 raw damage penetrates and does 0-5 points of actual damage!
What about averages? Ball does 2 and HP does 2. Huzzah, hit 'em again!
