a compressed air launched projectile?

 

[Nabob]

No, launched by the power of powder. The third picture is the base of the case.
Why does it have such a strange rim?

Bob

How about a decoy flare fired from an aircraft?

Not a flare or chaff.

CS round for RV85

As in barricade buster type. Mine says: 26.5 PS-CS-Nh inked on the hull. And jpw over 87 around the primer.

No, launched by the power of powder. The third picture is the base of the case.
Why does it have such a strange rim?

Bob

The chamber is recessed for use with these rounds. Regular 26.5 flares will work but must use an o-ring around the head to raise it enough to reach the breech face.
