SCIMITARS 20 ga. etc

The scimitar was an attempt to increase the stable range of the flechette projectile. It was also called a “glider” in some projects.

Shown here next to various flechette types.

The two types of loads most often encountered. 20 ga. shotshells.

Rare scimitars for .45 auto and 40mm m79

Ive got a 20 gauge scimitar in my collection.
It has a 2 1/2" case with 1" high brass and an Alcan h/s.
Looking down on the plastic carrier all you can see is the “X” shaped top
of the projectile. Is 20 gauge an unusual size for these?

These are 20ga. which is the “common” version.
