Okay, started a third run on the partially depleted cell, another 30% depletion (70% remaining in cell) run with a new 100% cell.
The fireworks from the rodeo started, so I turned off the porch light.
I'm standing there watching the fireworks, and noticed the PM6 in the bucket, went out.
Cool, I figure, it takes a bit after the light goes out, and I can turn the video camera back on, and maybe catch it in action.
All of a sudden, kablamo, a sharp pinging,
*BING*, not like the fireworks sound, but sharper, like a richocet.
Wife asks, "Whats that", I'm looking around wondering what just hit what from where and how.
Oh! I fire up my EDC, and look in the bucket. Aw, crap. I missed it, and now my PM6 is messed up.
This occured this time, within 41 minutes of starting the test, and within minute or two after the light went out.
After cool down, I'll don my protective equipment and go take some pictures.

In the last picture, you can see what is a chunk of the bulb assy spring, that partially unwound, and in other pictures, you can see it looks like it cut/fractured/snapped on the bulb assy itself. The bulb spring is shorter now...thats one hot exhaust, velocity, or both. Thanks Beamhead, for noticing this!
The threads don't work all that great anymore, in the tail assy, I think they got reformed or something. They used to be smooth, and work good, it was *pretty* darn hard to unscrew. Possibly it jumped a thread or two, during the bang.
Notice how the cell bases are now dented after the explosion and buldged.
For now, that will terminate any further testing.
I'll have to run to the store to get another one (after boxes of batteries over the past month, and having to get a new light, this testing stuff gets *really* spendy)
Thanks again to Kevin of Battery Station for providing free cells for testing purposes!
Does anyone know if the new PM6's are sealed? Maybe if I am lucky, I'll find an old one at the store. Any way from the outside of the package to tell the difference?
