herein is disposed tightly across and against the rear end of the rubber core 17 so as to urge the same against the inner surface of the end plate 13 and against the interior surface of the nose defining portions 12 as shown the flat forward end 20 of the soft metal core engages and is compressed against the rear surface of the rubber core the jacket 10 is substantially the same in fig5 as that shown in fig4 except that the scoring 22 extends rearwardly from the inner surface of the nose plate 13 and terminates rearwardly of the inflection point 15 the forward surface 24 of the rubber core 21 is compressed against the inner surface of the nose plate 13 by the concave forward end 25 of the metal core 23 which terminates at and bears against the rear surface of the rubber core 21 the bullet shown in fig5 is the preferred form of our invention it will be noted that the forward end of the metal core 23 is generally concaved or dished out to a depth of about 0 150 u2033 to 0 300 u2033 and the cavity thereof is filled with the rear end portion of the rubber core 21 we have found that this combination facilitates the expansion of the nose defining portions and the rubber core 21 as shown at the rear end of the bullet 10 the rear end portions 11 a of the cylindrical wall 11 are crimped inwardly around the rear end of the soft metal core 23 to effectively hold the metal core 23 in pressure bearing.
