Wow, I'm really impressed and grateful. Especially for a picture of a burst cone and explanation of DMG MOD which were the parts I didn't know. So just to clarify:
.233 ammo's 1/1 mod means no extra damage
5mm AP ammo's 2/3 mod means 33% less damage
5mm JHP ammo's 2/1 mod means 100% more damage
7.62 ammo's 12/10 mod means 20% more damage
So on 0 AC bluesuit without Toughness I can calculate following damage for char without BRD and 1 hex burst:
M60: 10(bullets in burst) x 30-40(potential dmg) x 120% (ammo dmg mod) = 300-400 x 120% = 360-480 dmg
LSW: 10 x 22-37 x 100% = 220-370 dmg
Avenger AP: 30 x 13-16 x 67% = 390-480 x 67% = 261-322 dmg
Avenger JHP: 30 x 13-16 x 200% = 390-480 x 200% = 780-960 dmg
That doesn't mean I'm about to kill bluesuits with 0 AP

I ignored other mods for sake of clarity.
