Preventing Thunder Distortion

I've been familiarizing myself with my new Sound Devices 722 and Shure VP88 
stereo mic by 
recording the numerous thunderstorms that have rumbled through Idaho this 
Although I've been careful to keep my volume levels low enough not to distort 
the loudest 
cracks of thunder, I find the occasional sound of distortion in playback.

When I look at the waveforms in ProTools, I don't see any clipping and they 
appear to be well 
below a distored level, yet I can hear it now and then (but not on all of the 
thunder, and not 
neccessarily on the loudest occurances).  

Do I need to change the Gain Range on the 722 from "normal" to "low" even 
though the 
overall level is lower than I'd like?  Any other suggestions?

Also, on a slightly different slant on sound levels,  I find that in general 
recording on any of 
my mics if I don't keep the volume near the top end of the level meter LEDs on 
the 722  (near 
the 0 dBFS mark), I get a far more anemic final level (as seen in a ProTools 
wave form) than I 
was accustomed to getting on my old Sony DAT recorder at what appeared to be 
moderate levels.  Any suggestion?
