Miniature ones.

Anybody ever done this?

Member Gatorgrabber and I were at my range Thursday past testing out his reconfigured AR carbine and rezeroing his eotech. After he was satisfied, he moved down to the 300 yard line to engage our steel man gong. I was standing over his shoulder watching and listening for hits.

A band from Sandy came over, and suddenly we were deluged. Gatorgrabber said FIDO( we were under shelter, just taking wind and spray), and kept firing.

This is when I noticed something odd.

While he was working his way through a 30 round mag, I started noticing an anomaly down range, a weird cloud puff when he fired. At first, I thought his rounds were disintegrating, but then I realized that his bullets were intersecting rain drops and vaporizing them, creating instant miniature clouds that appeared and disappeared in a second!

It didn't occur every shot, but fairly regularly as he blasted away, at random distances downrange.

Very cool to see, the little vapor clouds were not much bigger than my fist.

I have never seen this phenomenon before, 3000fps bullet intersecting large raindrops, but I cannot recall ever taking target practice in a heavy rain either.

Anybody else ever see it?

Sorry, we didn't have a camera with us, but I doubt any of my lo-grade equipment would have picked it up anyway. I tried looking for it on youtube, no luck.

I have never seen it but I have heard of it before.

One misty day, I was shooting with a friend and we could occasionally see 'vapor trails' along the bullet's flight paths. They didn't last long either. So short you couldn't see your own.

That's really cool. It'd be amazing to get some high-speed footage of that as it was happening. Did the shots with cloud-puffs seem to have their POI shifted to any significant degree, or were you not interacting with the guy regularly enough to know?

Couldn't really say, he was whacking a gong at 300 yards, running about 50% hits (windy), we couldn't see the point of impact, and he was unaware of the vapor puffs, probably because by the time he refocused from the recoil, they were gone.
