Damage Range for Big Bang?

That's the best I could do on Rash's, since they move. I was too tired last night when I leveled and maxed Big Bang to care where I tested it. From what I saw that was roughly the range; if you'd like I can find a stationary monster to try it on later, but in all honesty if I got the range wrong I was off by an eighth of a centimeter or so, and another screenshot would just look the same.

I can do 70ks tops on mobs, if you wanted a damage idea. Damage range is nice because of the 80% mastery, so I was hitting anywhere from 62k-80k charged, 9k-15k uncharged.

Looks like 170-180% ice strike/explosion range horizontally.
