Abstract

A subcaliber arrow projectile includes a projectile body which has a rearwardly widening, conical projectile tip having a forward point and a rearward base, whose caliber corresponds to the projectile caliber. The projectile body further has a rearwardly widening, resistance-stabilizing conical rear part immediately adjoining the base of the projectile tip. The rear part has an enlarged caliber which is greater than the projectile caliber.

Claims

1. Practice ammunition comprising a subcaliber arrow projectile including a projectile body;

said projectile body having

(a) a conical projectile tip having a forward point and a rearward cone base;

said base having a caliber corresponding to the projectile caliber;

said conical projectile tip having a forwardly-oriented cone angle; and

(b) a conical rear part immediately adjoining said base of said conical projectile tip;

said conical rear part having a forwardly-oriented cone angle greater than said cone angle of said conical projectile tip said conical rear part having an enlarged caliber greater than said projectile caliber.

2. Practice ammunition as defined in claim 1, wherein said rear part has, in a zone of said enlarged caliber, a plurality of generally axially extending holes.

3. Practice ammunition as defined in claim 1, wherein said rear part has a rearwardly oriented, rearwardly widening frustoconical bay.

4. Practice ammunition as defined in claim 1, wherein said projectile body is a one-piece cast component.

5. Practice ammunition as defined in claim 1, further comprising

(a) a multi-part discarding guiding sabot surrounding said projectile body and having, at a rear sabot portion, an inwardly oriented circumferential groove;

and

(b) a propelling disk having a peripheral region received by said circumferential groove.

6. Practice ammunition as defined in claim 5, wherein said sabot is of plastic.

7. Practice ammunition comprising a subcaliber arrow projectile including a single-piece, cast projectile body;

said projectile body having

(a) a conical projectile tip including a forward point and a rearward cone base;

said base having a caliber corresponding to the projectile caliber; and

(b) a conical rear part immediately adjoining said base of said conical projectile tip;

said rear part having

(1) an enlarged caliber greater than said projectile caliber;

(2) a plurality of generally axially extending holes in a zone of said enlarged caliber; and

(3) a rearwardly oriented, rearwardly widening frustoconical bay.

8. The practice ammunition as defined in claim 7, further comprising

(a) a multi-part discarding guiding sabot surrounding said projectile body and having, at a rear sabot portion, an inwardly oriented circumferential groove;

and

(b) a propelling disk having a peripheral region received by said circumferential groove.
