Definitions

  • Expanding bullets comprise a core of soft malleable material, such as lead or an alloy lead, and a relatively hard jacket of any suitable material, usually copper-base alloy, capable of resisting stripping from the core while being capable of taking not only the rifling, but also the mushrooming action.
  • a core of soft malleable material such as lead or an alloy lead
  • a relatively hard jacket of any suitable material usually copper-base alloy, capable of resisting stripping from the core while being capable of taking not only the rifling, but also the mushrooming action.
  • the jacket may completely enclose the core, or leave a nose portion of soft core material protruding from it to make in the latter instance, a soft point type of bullet.
  • the jacket is designed to enable deformation largely at the nose without separation of the jacket from the rest of the core.
  • Such a jacket generally includes at least a base jacket and sometimes also includes a tip jacket, generally thinner and more easily deformed than the base jacket.
  • FIG. 1 is an elevational side view of one embodiment of the projectile according to this invention.
  • FIG. 2 is a transverse cross sectional view of the em bodiment of FIGURE 1 taken slightly to the rear of line IIII after enlargement;
  • FIG. 3 is another elevational side view of a still further preferred embodiment shown partly in section adjacent the base;
  • FIG. 4 is a transverse section taken slightly to the rear of line IV-IV of FIGURE 3 after enlargement;
  • FIG. 5 is an elevational side view in longitudinal cross section showing a die apparatus with a preliminary assembly positioned therein for an intermediate manufacturing operation for making a bullet of this invention
  • FIG. 6 is an end view taken on line VI-VI looking down upon the assembly of FIGURE 5 after completion of the operation shown;
  • FIG. 7 is an elevational side view showing a point shaping die in cross section and the completed bullet partly in section at and adjacent the nose.
  • an expanding bullet similar to the type shown in the above noted patents, but having a base jacket constructed with special creasing and swaging at the mouth so as to achieve a splitting or at least a proclivity to splitting along predetermined lines while at the same time offering yielding but firm support to the expanding core with a scoop-like unfolding structure to avoid excessive core fragmentation and separation. This is done without cutting away and removing any part of the much needed jacket support to give a significant improvement in uniformity of mushrooming, particularly at maximum ranges, i.e. at the lowest velocities.
  • the improvement is obtained by inward, pinch-pleating the tapering mouth of the base jacket by means of creasing in such a way as to form staves and a plurality of deeply inwardly extending folded webs, each between adjoining staves to form stave-like flanged panels at the edge of the jacket.
  • Each folded web involves one very sharp bend, a single 180 bend, at which the metal is overstressed to have at least a pronounced proclivity to split.
  • the webs and a like number of staves form either an uninterrupted continuation or an abutted array of each other around the circumference at the mouth from jacket metal of substantially uniform thickness circumferentially.
  • Each stave or panel is flanged at its margins; and the staves are abutted at least at their flanges.
  • flanged slits preferably are formed in the jacket wall at the edge.
  • the resulting flanged and abutted stave structure of the jacket edge provides desired core support while permitting expansion with improved uniformity. Splitting is achieved by severe working rather than by complete removal of part of the jacket edge.
  • Each resulting stave-like panel member is a part of the jacket wall which is thinner along its length than the wall of the rest of the jacket and preferably tapers in thickness in each panel to a finitely thick edge providing thinner section at the edge of the mouth as compared to the relatively thick posterior portion of the rest of the. base jacket, which is locked to the soft core by one or more cannelures involving knurls of the type shown in prior US. Patent 1,730,871, which provides an interior portion of the jacket of decreased diameter.
  • the longitudinally extending staves or panels take the form of from three to nine, but preferably from five to seven, and usually six, marginally flanged, longitudinally as well as circumferentially curved staves not only integral with the rest of the jacket but also at least contiguous, if not integral as well with adjacent sectors.
  • Adjoining staves are buttressed and are largely interconnected by a tapering pinch pleated structure providing the greatest marginal flanging at the open edge of the base jacket but tapering to the least flanging at the root of each where the staves join the rest of the jacket.
  • the minimum inward extension of each flange at the edge must exceed the thickness of the jacket edge and is preferably not less than about 1%.
  • the extension does not exceed about five times the thickness of the base jacket material at the edge, which varies from about 0.010 of an inch to about from 0.015 of an inch for the small arms ammunition contemplated according to this invention.
  • the pleated web therefore, should extend inwardly at its leading edge to an internal diameter from about to about of an inch less than the exterior diameter at the edge of the jacket at the mouth.
  • the entire edge of the base jacket at the nose is sloped rearwardly with respect to the axis of the bullet to provide an outwardly flared, but unnotched and unscalloped edge including the substantially identically beveled leading edge of the pleated flange and rib forming webs.
  • the slope is substantially at a right angle to the jacket curvature tangent.
  • this bevel Upon impact this bevel provides a wedge action on the protruding nose of the bullet to advantageously initiate the outward expansion of the core in all radial directions uniformly.
  • This invention requires that in the pleated region there be an abutted substantially double flange structure substantially thicker circumferentially than the greatest wall thickness of the adjacent sectors. As shown and described, it is about double.
  • the jacket metal is gradually deformed except at the apex or sharp inner bend of the cusp where bending is sufliciently severe to create a single line of proclivity to splitting, leaving the flanges integral with the staves, or to fracture the jacket along these lines.
  • the indentations are achieved with a pie-cut edge creaser having a circumferential array of radial directed wings or fins corresponding in number to the number of pleats desired at the open end of the jacket.
  • This sort of creasing turns in the open end of the jacket to form a frusto conical shape (FIGURE 6) having a circumferentially spaced series of edge flutes and cusps at the latter of which the pleated web will be formed in the final swaging operation.
  • suflicient inward extension and thickness in the pleated region to make a sufficiently severe bend and thereby achieve a predetermined line of preferential splitting Without'any jacket cutting or difficult jacket drawing to create grooves, indentations, or scallops.
  • Projectiles like those shown in FIGURES 1 and 3 made according to this invention include among others, bullets known as .243 Winchester 100 grain soft point bullets, .270 Winchester 150 grain soft point bullets, 30-30 Winchester 170 grain soft point bullets, .308 Winchester 180 grain soft point bullets 30-06 Springfield 220 grain soft point bullets, and various other expanding bullets of still other calibers and weights.
  • the bullet has a base jacket 1 from the open edge 2 of which there protrudes a nose portion 21 of the soft core 20. Bordering the nose there is thin jacket portion 3 having the substantially full circular annular jacket edge 2 on the outside of which there are longitudinally extending parting lines indicative of the existence of uniformly distributed rather tightly closed internally projecting pinch pleats 8.
  • the lines are at the apex of tiny cusps at the edge 2 and tapering away from it to a hairline.
  • the longitudinal extension is not great and usually is about from one to two times the average circumferential expanse of ,each panel 9 produced because of the internal structure better shown in FIGURE 2.
  • Each pinch pleat 8 consists of a pair of flanges 11 and 12 which are integral extensions of the lateral margins of the staves 9. These are abutted internally along a line 10 at which the flanges 11 and 12 are in contiguity at least adjacent theirinner ends at which the flanges are at least partially split from each other, however along only a very small part of the length at the inner end 13 of each pinch pleat 8. Therefore, the alternate pleats and panels form a continuous array of flanged metal staves adjacent the jacket edge 2 interrupted by no spaces.
  • each pleat 8 is substantially equal to make each pleat 8 an internal rib of about twice the thickness extending inwardly by more than the double thickness.
  • the mouth portion 3 of jacket 1 tapers from least thickness at the edge 2 to maximum thickness where it adjoins the thicker rear part 4 of the base jacket where the jacket is provided with a knurl 6 forming a circumferential indentation in the thick circular cylindrical wall of the base jacket.
  • each pleat 8 becomes not only shallower but its web thicker so that splitting by fracture at 13 occurs only at edge 2.
  • the bullet also comprises a base jacket 1 and a soft core 20. Adjacent the base 5 of the jacket there is the relatively thick cylindrical wall portion 4 having not only knurl 6 but also another circumferential knurl 7 closer to the base 5. These form a reduced internal part of the jacket for better holding the core in it. Adjacent the frontedge 2 of the jacket there is a thinner walled tapered jacket wall. 3 formed with part of the bullet ogive and a plurality of pinch pleats 8 which, however, extend inwardly somewhat more deeply and form a series of more pronounced tapered recesses or cusps in the jacket wall at the edge of the jacket.
  • the cup 101 has a posterior portion of greatest thickness adjacent its closed base and also a tapering anterior portion 103 terminating in the edge 102 of the open end of the cup. Similar thinness may be obtainable by a conical flare terminating in an enlarged cylindrical portion adjacent the edge 102. Either of these types of cups will provide a suitable thin front end 103 for making the ogival part 3 of the finished bullet jacket 1 shown in FIGURES 1-4.
  • the thin walled portion 103 is creased with a crimping die 50 having in its cavity 51 a suitable number, such as six, of radially arrayed equally spaced creasing fins 52.
  • a suitable number such as six
  • these fins crease the cup 101 at 108 until there is developed the intermediate foil shaped edge and flutes 109 shown in FIGURE 6.
  • the crimped assembly is then subjected to a further operation in a suitable female swaging die 30, the interior contour of which corresponds to the desired finished contour for the projectile at its nose and along its sides.
  • a suitable female swaging die 30 the interior contour of which corresponds to the desired finished contour for the projectile at its nose and along its sides.
  • punch 31 moves in during swaging, the circumference of the anterior portion 3 of the jacket 1 is reduced as the pinch pleats 8 are formed to make the final finished tapered part at the mouth of the jacket.
  • Swaging causes the web to fold inwardly to provide a series of ribs of double thickness projecting from the adjacent sectors without any thinning and with little, if any, work hardening except at the inner-most fold at the midpoint 13 or 13" of the web in the finished rib.
  • scallops 22 are provided on the relatively soft nose by drawing or extruding extensions from the core. These extend rearwardly from this portion to overlie and fill at least the most open part of any cusp space which might be formed between the staves at each pinch pleat at the base jacket edge.
  • This scalloping of the core provides a more nearly smooth bullet periphery circumferentially which is desirother suitable indentation, producing an interior portion of decreased diameter in the wall of the jacket to indent the core and thereby interlocking the jacket and core.
  • the expansion action of the structure of this invention appears to be more uniform because of. the combination of (a) relatively thin paneling in the staves and (b) regular, thick and rather deep internal webbing, which notches the core while reinforcing the paneling longitudinally.
  • the combination at first requires unfolding and only thereafter spreads or splits easily while simultaneously increasing in resistance. This minimizes erratic upsetting of the core all the way up to maximum impact because it gives a preferred variation in the tendency of the jacket to tear at regularly spaced intervals with the least initial resistance at the lowest velocities of impact and with the most final resistance at the end of impact at highest velocity.
  • the finished bullet because of the liberal pleating and heavy webbing provides pre-splitting with edge reinforcement at the very edge of the jacket.
  • the flanged split offers the least resistance to expansion on account of accordian action while at the same time offering desired initial momentary delay in expansion in the initial circumferential confinement to the expanding core on account of the fianging.
  • expansion occurs readily even at distant ranges where the energy is considerably spent and the velocity low, but premature mushrooming is avoided to allow sufficient penetration of the bullet to occur first.
  • the leading edge of the relatively heavy double flange being deeper than the rest of the flange improves the delaying action.
  • each pinch pleat the metal of the jacket is severely worked but is most severely worked and usually split at the leading edge and the least worked adjacent the root of each stave where it joins the rest of the jacket.
  • Each is thus made prone to progressive splitting at extreme stages of any degree of expansion including the severest expansion reached at higher velocities; and this together with the notches or voids in the core, made by the unfolding pleats back of the nose, controls the expansion so as to make it more uniform both circumferentially as well as radially in all directions at any given velocity.
  • the voids take part of the deformed nose inside rather than outside the jacket to aid expansion.
  • a relatively hard jacket having a closed base and a thinned nose edge remote from said base, said jacket at said nose edge forming at least but not more than 7 ogivally converging and circumferentially abutting staves and between adjacent staves an intervening folded web at least partially joining adjacent staves and forming on said staves substantially radially extending marginal flanges for abutting adjacent staves in contiguity with each other at said flanges to define an equal number of uniformly circumferentially distributed longitudinal ribs on the interior of said jacket adjacent said edge, said staves at any given transverse cross sectional plane being-of substantially uniform thickness radially and said web of about the same thickness in said given plane transverse to the bullet axis such that said ribs have a circumferential thickness about twice the thickness of said staves measured in said plane and extend inwardly from said staves most deeply at said edge to a depth in excess of the thickness of said staves at said
