[QUOTE="Ian M, post: 21153, member: 25"] Guys, Interesting that there are several terms used to describe the viewing of bullets in flight. Trace, wash and up here we call it swirl. Not sure if there is also a term for seeing the glint of reflected light off the base of the bullet? One of the most interesting examples of trace that I have experienced occurs when we shoot .22 LR target ammo at 100 yards, with the sun behing the shooter. We can see the swirl of the bullet trajectory and for a split second the shadow of the bullet on the target paper and they appear to converge into a black hole as the bullet strikes the paper. The shadow appears as a black blur that moves upward, the swirl drops down into the bullet hole. I have seen this many times through the riflescope as I shoot - also have seen it while shooting indoors. We played around shooting at clay birds out on the 300 yard backstop one day and the swirl of the .22 LR rounds was very easy to watch. I have also seen extremely slow moving bullets shot indoors in very good light where we could see the swirl, or bullet more correctly, without optics. These were big slow bullets, they were subsonic. I agree with Darryl, you want to be directly behind the shooter, looking down the bullet path and the better the optics the better the chance of seeing swirl. My favorite scope for that is the Nikon 78mm ED Fieldscope - it is pretty much in a class by itself for sharpness and brightness. I suspect that the position of the sun, relative to the bullet path is also very important, perhaps also how low it is in the sky. We frequently see great swirl during the last couple of hours of shooting light. Cloudy days are usually a bust. Also busy backgrounds make it harder to see swirl - brush or whatever. Most really long shots involve the trajectory coming down from about the horizon, easier to see against the sky. Good luck with your photo project. ian [/QUOTE]
