WCC 45 ACP with Red X in Bullet Tip

I found this WCC 42 45 ACP. It has a red “X” impressed in the bullet tip. Vol 2 of Hackley, Wooden and Scranton mention a Frankford Arsenal tracer with an X impressed in to the bullet tip. Is this one of those?

Thanks

This one reminds me much of the T30 tracer:

Yes, missing the rest of the tip color. But you can see the line were it ended a the arrow tip

I did notice the paint or lack of paint line on the bullet tip. I was under the impression the tracer bullets had a lead tip core and gilding metal jackets. This bullet is attracted to a magnet.

This is not my area of interest so I plead ignorance.

Thanks for the reply,

Paul
