ABSTRACT:
An improved construction and support for a twist-reducing ring carried on a stabilized projectile is described. The ring, which is rotatably supported in an annular groove in a portion of the projectile jacket, is formed from a plurality of circumferentially abutting, axially aligned powdered metal segments. Such segments, which are released upon separation of the projectile from the surrounding cartridge case, are initially retained in place either by the front wall of the cartridge or by a separate, easily destructible auxiliary ring. The ring segments are either directly rotatably engaged with the bottom wall of the annular groove, or are housed within a separate U-shaped container which, in turn is slidably mounted in the groove.
