Ah, but it's that first bang we're interested in, isn't it?  And doncha
think the peak current in that first pulse is a wee bit higher than 12 amps?

Indeed.  I would expect the losses to be at least that high, but I didn't
think (there I go again, not thinking) that a mere 3 ohms would account for
such losses.  Maybe I should have broken out my calculator.  :)

Makes sense.
