Winchester briefly made an actual tracer Mark 5 shell in the 60s
The Winchester TrAAckers were discontinued as the colored wad and 1/8 oz of shot didn't necessarily go where the shot went, and depending on the background were hard to see.

I'm with Stan. Esp. from behind the shooter the shot cloud is easy to see.

I hope it's not dominance shifting as missing shallow angle outgoers from left to right was the onset of my curse frown
