Great video, I really like this sort of thing, I shoot F-Class and we see the trace of others often, rarely the bullet itself or base.
We do a LOT of spotlighting here and I can’t remember a night that we don’t see some of the bullet bases shine on their way to the animal, interesting how each calibre has a different trajectory that is plainly visible.

My 44Mag carbine has a rainbow trajectory as the bullet is only seen in the light as it drops down on it’s way about half of the distance at 150mtr to the animal. Most fast calibres still have a visible arc to it’s travel though.

It amazes me how slow it actually appears, the first few times I honestly believed I was seeing something that wasn’t there, but my Uncle assured me that it was the bullet and I was seeing in real time it’s flight.

Cheers.
