Tracers with PGU-28/B Improved 20mm Rounds

[Alan Berry]

What tracer rounds are used with the longer range PGU-28/B 20mm
cartidges? I cannot find reference to a (non-target-practice) tracer
with equivalent ballistics.

My unit used NTP tracers manufactured by Hewlett-Packard and DuPont
joint venture. About 27% were duds.
