Expansion of soft-point bullets can be facilitated further by scalloping the mouth of the jacket or cutting five or six notches around the jacket mouth. 0000010719 00000 n <<8030D006D4BCC24B96330164C6919E01>]>> 0000013598 00000 n 0000085138 00000 n They are easily recognized by their long length and deep cannelures for lubricants (Figure 7.1).

The destabilized bullet by an impact with the dorsal hand experiences a yawing to tumbling motion in flight. 5.56-mm bullets break up in the body, the tip of the bullet tends to break off at the cannelure with the tip remaining relatively intact, while the lead core and the rest of the jacket shred (Figure 7.6 A-B). The bullet does not explode in the body; it does, however, have a tendency to rapidly destabilize, bending at the cannelure, resulting in lead core being "squirted" out the base. 0000086091 00000 n 0000068035 00000 n Now at first blush this sounds like it would be pretty effective for self defense. 0 This phenomenon induces atypical entrance wounds and atypical X-rays. 0000008317 00000 n 0000086622 00000 n startxref The jacket encloses the tip of the bullet, preventing it from expanding when it reaches its target.

Law of Attraction Subconscious Mind Power, About Just like the 55-gr. Thus, the degree of expansion can be controlled by the thickness and hardness of the jacket, the location of the bullet cannelure, the amount of lead exposed, the shape of the bullet, the composition of the lead core (antimony is often added to the lead), and the design characteristic of the bullet. The lead core is exposed at the tip so as to facilitate expansion when the bullet strikes. 0000002985 00000 n Note the presence of the "bronze point. 0000014210 00000 n Here the jacket is "H" shaped such that the lead core is in two segments, one above and the other below the horizontal bar of the "H".
