I have often wondered why folks would be so interested in low flash powders, flash suppressors and silencers, then use some sort of tracer ammo?
Unless there is a group of you concentrating fire on the enemy, it would seem the tracer would point directly to its point of origin.
But then, I have never been the brightest bulb in the box.
(You will note how I got the "bright" pun in with tracer comment?)
Of course, I completely understand whizzing lighted rounds downrange just for fun or in combat aircraft applications.
