I tested this round in numerous videos over time. It has been tested against mild steel, AR500 plate, concrete, and timber. This round puts on an impressive smoke and fire show upon impacting a hard target. Detonation occurs reliably against thick steel but doesn’t seem to be triggered upon impacting concrete, wood, or thin metal. This tells us that the incendiary compound is not overly sensitive.
The bullet has a 2 part jacket. Black over red painted tips were indicators of rounds manufactured prior to 1966, then black only tips thereafter. The penetrating core is not mild steel but a true hardened penetrator. I have not yet conducted hardness tests but my assumption is that it is a molybdenum based core and probably has a brinell hardness of about 700 HB.
This round reliably penetrates 3/4″ thick mild steel when fired from a WASR-10 AK. An interesting observation is that plant life immediately exposed to the smoke seems to shrivel and die within days.

Photos and Packaging:
These came packaged in a wooden crate containing 1440 rounds in two solder sealed tins. Each “spam can” contained 720 rounds in paper wrapped packages. A can opener is not necessary, the cans peel open with a tab. The tins had a black rectangle painted on them which indicated the color of the bullet tips. Note, the packaging shown below is of the post 1966 chinese API which has a black tip instead of black over red.
