Quote:"And finally, the FABRL bullet made a very poor tracer."That reminds me of what I've seen in other forums: Everybody wants to talk about their concept of the "perfect" bullet for the standard load fired in rifle and carbine, but almost nobody wants to discuss if it's even feasible to make a matching tracer round. Ya gotta have tracer ammo for your sheen guns!
In addition to COL Hackley's comment (above) about a FABRL tracer, I have never seen anything to indicate that the CETME bullet ever had a matching tracer developed. That may be instructive to consider when thinking about using a similar exotic design for the ball projectile.
If the goal can't be achieved with conventional FMJ (or M855A1) configuration, with a steel or steel/copper core, maybe it just can't be done?
