The sun comes up directly to my back at the range where I shoot. Early in the AM, when the sun is just right I can do the same with 22's and handgun bullets. Can't do it unless the sun is just right. I've never seen a center fire bullet in flight, but slower loads, lots of times.

If you sit behind a long range rifle shooter with a spotting scope, you can see the "trace" of the bullet all the time that its trajectory puts it in your scope's field of view. It is not fire from a tracer bullet, nor is it the glint off the base of a backlighted bullet. It is the refraction pattern of the shockwave of the fast moving bullet. See Schlieren photography.

And when the atmosphere is compressed moisture becomes visible.
