On the IAA eJournal 487, page 28, we can see a picture of a cutaway of a .50 tracer cartridge (picture N° 2)
The caption says “Tracer, USA, red tip. Headstamp is R A 52”
I am surprised by the tip color, I thought it would be brown (tracer M17)
Does the tracer M1 yet made in 1952 ?
Thank for your reponse
