Los cartuchos Dum-Dum ya no existen como tal, pero tienen el privilegio de ser las primeras balas expansivas del mundo, nacen al rededor de 1889 cuando los ingleses se encuentran conquistando los territorios de La India y Nepal. Recientemente los Britanicos habian adoptado el Calibre .303, en sustitucion del 11 Milimetros Martini-Henry de polvora negra y plomo desnudo, el problema se les presento cuando los guerreros de aquellas tierras se les avalanzaban encima totalmente drogados con opio, con una espada en la mano y muy malas intenciones, de modo que cerca del arsenal estatal de Dum-Dum, cerca de Calcuta en la India, un capitan ingles de apellido Lewis comezo a experimentar con diversas formas de hacer que los proyectiles FMJ fueran expansivos, Tuvo cierto exito pero inmediatamente fueron prohibidos para la guerra convencional por sus "Efectos Devastadores", por tanto nunca se volvieron a usar en el campo militar, sin embargo tienen la importancia de ser el punto de partida de las investigaciones que desarrollaron los proyectiles expansivos usados en la caza deportiva. Erroneamente se utiliza el termino Dum-Dum para hacer referencia a los proyectiles expansivos. Aqui tienes una foto referencial para que veas mas o menos de que se tratan las balas dum-dum

Balas DUM-DUM: es la variante más antigua de bala semiblindad con líneas de precorte. Se desarrollaron en el arsenal indio de Dum-Dum a finales del S. XIX para aumentar el poder del .303 British. Simplemente eran balas normales con unos cortes en la punta para facilitar la deformación al romperse la envuelta. La envuelta solía romperse dejando esquirlas y heridas terribles. Fueron la causa de que se prohibiese las balas expansivas en la guerra. Al usarse balas militares que no tenían envuelta en la parte posterior, a veces ocurría que la envuelta quedaba atascada en el cañón aunque saliese el núcleo de plomo. El siguiente disparo podía provocar la explosión del arma.

En la época que se empezaron a usar las puntas FMJ de pequeño diámetro (comparado con los viejos calibres de pólvora negra) y altas velocidades, las balas de fusil tenían una velocidad sólo un poco por encima de 2000 fps. La envuelta era necesaria por las velocidades altas, y esto hacía que las puntas fueran casi indeformables al impactar contra tejido blando a estas velocidades.
Además estos proyectiles tenían un punta redondeada (bastante roma) y mucho peso, lo cual los hacía esencialmente proyectiles casi cilíndricos, con la masa muy balanceada. Esto hacía que estos proyectiles no volteen en el cuerpo fácilmente al impactar, casi todas las heridas que no involucraban hueso eran de un diámetro menor que el proyectil y atravesaban limpiamente al oponente en línea casi recta, sin shock hidráulico ni heridas desgarrantes debido al vuelco del proyectil en el cuerpo.
Enseguida los cirujanos militares se dieron cuenta que estas nuevas armas eran excesivamente "humanas" y que las heridas eran muy inferiores a las producidas por los viejos calibres de pólvora negra (baja velocidad, pero puntas de plomo desnudo de grán diámetro y deformables), y se empezaron a buscar nuevas opciones. Como las puntas tipo Dum-Dum se mostraron muy efectivas se proscribió su uso (sólo entre los países signatarios) en el tratado emergente de la convención de La Haya de 1899.
Sin embargo, cuando los alemanes adoptaron las puntas más livianas con forma spitzer (con la intención de aumentar la velocidad de la bala y hacerla más aerodinámica para mejorar su trayectoria), fueron rápidamente copiados por todas las potencias. Como beneficio adicional se descubrió que estas balas de alta velocidad (> 2400 fps) transmiten mayor shock hidráulico y se desbalancean mucho más fácilmente al penetrar el cuerpo, por lo que vuelcan y producen heridas mucho mayores, incluso si no se deforman ni fragmentan. Este es el tipo de punta militar (spitzer, o spitzer con boat tail) utilizado hasta ahora.

Aca en PR se consiguen una balas que en la punta tienen un fulminate empotrado, que al dar contra huesos o tejidos duros, el mismo estalla y desplega esquirlas y pedazos de metralla del mismo proyectil...como una granada en miniatura...Las fabrica la Winchester y Federal, vienen en 9mm, .380, 38, 45 y .40.
Huelga decir que por la naturaleza de los daños que hacen, estan prohibidas en muchos lugares, incluyendo PR, pero como todo, se consiguen si las buscas ..... Yo he tirado con ellas, pero no he podido notar la diferencia entre ellas y mis balas regulares.

Estas balas no existen (al menos en las marcas mencionadas), probablemente te estas confundiendo con las de punta hueca, que no tienen ningun fulminante en la punta sino que simplemente se expanden al impactar por el efecto de la presion hidraulica...

No amigo mio, tienen un fulminante de mercurio en la parte frontal, tengo en mi poder par de cajas de ella, como equivocarme....es un poco mas pequeño que el detonador posterior.
Gracias

Puedes subir una foto (incluídas las cajas), o un link al sitio del fabricante? Has desarmado alguna punta para asegurarte que sea un fulminante?
Como te dije anteriormente, Winchester y Federal no fabrican esos cartuchos.

El modelo es el "Devastator", este tipo de bala fueron las que usaron para el atentado contra el presidente Reagan en los EUA..... Si lo buscas en el internet, solo pinchas Devastator bullets" y te llevara a ellas....suerte
Inclusive, muchos cuerpos de la policia la usan, pues dicen que reducen los daños colaterales....ya que el proyectil no pasa a trvez del cuerpo hiriendo a otras personas no involucradas.
Son muchas las cosas que no son posibles pero que si estan ocurriendo y que las mantienen fuera del conocimiento de la poblacion en general....por eso a mi edad aprendi ya a no decir " eso es imposible" jajaaja El ejercito americano las usa y ciertas dependencias que se relacionan con espionaje y asuntos chuecos como la CIA, las usan tambien.
Estas balas estan vivitas y coleando hace ratito...

Esta marca Hi-Vel básicamente hace "novelty" munición para los incautos que tienen una vívida imaginación y que se dejan impresionar por cualquier propaganda grandilocuente.
NINGUN cuerpo de policía de USA, de sus organismos federales (FBI, DEA, etc.), o de sus fuerzas armadas usa este tipo de munición, por su poca confiabilidad (muchas veces no detonan), pésimo control de calidad, y baja penetración.
http://en.wikipedia.org/wiki/Reagan_assassination_attempt
"Sixteen minutes after the assassination attempt, the ATF found that the gun had been purchased at Rocky's Pawn Shop in Dallas, Texas.[15] It had been loaded with six "Devastator"-brand .22LR cartridges, which contained small lead azide explosive charges. The rounds were not manufactured in the U.S.; any bullet which contained actual explosives would have been classified as an illegal explosive device under U.S. federal law at the time that Hinckley purchased them. All six bullets failed to explode."
Como te dije antes, ni Winchester ni Federal hacen estos cartuchos, como habías afirmado.

Como dice TF. Las balas mencionadas son un intento mas de sacarle dinero a los incautos. Desgraciadamente la sobrepenetración, con sus posibles consecuencias negativas, es muy difícil de separar del "stopping power" en balas para armas convencionales.
Siempre es bueno ser escéptico cuando alguien afirma lo contrario.

Description:
BACKGROUND OF INVENTION
RELATED APPLICATIONS
There are no applications related hereto now filed in this or any foreign country.
combine the advantages of using an explosive charge to provide additional shock and to fragment or mushroom small arms bullets to provide a substantially greater stopping-power than the same bullet with the same velocity would have without the features and generally a greater stopping-power than would be had by any of the non-exploding mushrooming and fragmenting bullets of present day commerce. In so doing I use existing jacketed small arms bullets of present day commerce and modify them to embody my invention therein. I provide a simple impact detonating system for my explosive charge that is created from existing munition elements but yet provides for appropriate handling safety, positive detonation upon impact and no predetonation in a gun barrel. The explosive force of my bullet may be used with appropriately designed bullets to either enhance mushrooming, fragmentation or both as desired depending upon bullet construction. My invention may be embodied in a bullet at a cost not substantially greater than that of the present day jacketed bullet of similar type and yet is extremely reliable and relatively safe.
SUMMARY OF INVENTION
My invention in general provides a jacketed bullet defining a medial chamber carrying an explosive charge and preferably an anvil that contacts an associated detonator to initiate an explosion upon impact of the bullet with a target.
I modify an ordinary metal jacketed lead alloy bullet of commerce to embody my invention by boring an axially aligned cylindrical hole from the apex through the core and into the base of the bullet jacket. I preferably place in this chamber a metallic anvil of either spherical or rod shape that is relatively free to move in a direction parallel to the bullet axis. A charge of explosive, commonly of the black powder type, is placed in the chamber and the front end is closed with an ordinary cup type small arms primer of present day commerce. The primer is seated with its open portion facing the explosive charge and its base slightly below the level of the tip of the bullet so that the primer may not be accidentally detonated during handling or loading operations. The primer is positionally maintained by adhesion to the bullet core walls defining the explosive chamber. The completed bullet is loaded into an appropriate cartridge case in the normal fashion and fired as any other bullet. Upon impact the detonator will ignite the explosive charge to cause an explosion which will either accentuate the bullet mushrooming or fragmentation and create additional schocking-power to fulfill the objectives of my invention.
In creating such a bullet it is:
A principal object to provide a small arms bullet with an explosive charge that detonates upon impact to enhance bullet stopping-power.
A further object to create such an explosive bullet that may be formed by modifying existing small arms bullets of commerce.
A further object to provide such a bullet that may use the force of its explosion to enhance the mushrooming, fragmentation or both depending upon bullet design.
A still further object to provide such an explosive bullet that is most sure of detonation upon impact but yet is relatively safe during handling and loading processes and may be otherwise used as ordinary bullets of similar nature.
A still further object of my invention to provide such an explosive bullet that may be formed by relatively simple operations and by the use of standard ordinance parts of commerce to provide a product of relatively low cost.
A still further object of my invention to provide such an explosive bullet that is of new and novel design, of rugged and durable nature and simple and economic manufacture and one otherwise well suited to the uses and purposes for which it is intended.
Other and further objects of my invention will appear from the following specification and accompanying drawings which form a part hereof. In carrying out the objects of my invention, however, it is to be understood that its essential features are susceptible of change in design and structural arrangement with only one preferred and practical embodiment being illustrated in the accompanying drawings as is required.
BRIEF DESCRIPTION OF DRAWINGS
In the accompanying drawings which form a part hereof and wherein like numbers of reference refer to similar parts throughout:
.
DESCRIPTION OF THE PREFERRED EMBODIMENT
My invention provides generally jacketed bullet 11 defining a medial axially aligned explosive chamber carrying explosive 14 and detonator anvil 12 with cup type primer 13 sealing the forward end of the chamber.
A typical hand gun cartridge 10, in this case a 0.45 caliber ACP, is shown in the illustration of FIG. 1, where it is seen to provide cylindrical cartridge case 15 terminating in forward bullet holding mouth 16 and defining in its rearward part ejector groove 17 and rim 18. Bullet 11 is seated in mouth 16 and normally positionally maintained by frictional engagement though in some instances it may be sealed or adhered therein. Though designs vary widely, all small arms ammunition insofar as my invention is concerned have essentially the same parts, although commonly in rifle shells mouth 16 will be necked down to a smaller diameter than case 15 and oftentimes in some shells there will be no ejection groove 17 in which case rim 18 is of larger diameter than case 15. The explosive bullet of my invention, however, may generally be used with all such small arms cartridges.
It has been found most desirable to define some indentation or small hole in the inner surface of the medial portion of base 19 of the bullet jacket to create the utmost stopping-power for the bullet. If explosive chamber 23 be formed by drilling, this indentation 24 may be conveniently formed by the point of the drill that forms the chamber. The exact nature or size of the indentation has not been found to be too critical but mushrooming and fragmentation effects both seem to be enhanced if the medial portion of the base be weakened to some degree. Obviously this indentation should be such as to prevent passage of explosive in the explosive chamber therethrough and prevent ignition of such explosive during the firing of the bullet.
A detonator anvil preferably is carried in explosive chamber 23 to aid the detonation of the primer 13. The purpose of this anvil is to provide impact on the inner side of primer 13 and the anvil may therefore take several shapes and yet accomplish its purpose. The particular anvil 25 shown in the illustration of FIG. 4 takes the shape of a cylindrical rod having both a diameter and length somewhat less than that of explosive chamber 23. The form of anvil 26 shown in the cross-sectional view of FIG. 5 and in FIG. 7 takes the form of a sphere of a diameter slightly less than that of the explosive chamber. Either form of anvil seems to function well though obviously the details of the functioning must be somewhat different in the two cases. The anvil is not an absolute necessity in my invention as the detonator will generally institute explosion upon impact without the anvil, but it was found that when no anvil was used there would be some misfires ranging in about the five percent range. With the use of either of the anvils illustrated there are substantially no misfires upon bullet impact even in extremely soft matter such as congealed gelatin or fruit.
Explosive 14 is some type of explosive material that may be detonated by primer 13. I prefer to use ordinary fine grained black power of commerce though the modern day black powder substitutes such as Pyrodex of the Hodgen Powder Company and many of the trinitrotolune, nitrocellulose and nitroglycerine based smokeless powders of present day commerce will serve the purposes of my invention though the nature and effect of their explosion may be somewhat different. The only particular requirements of this explosive are that it be detonated by primer 13 upon the explosion of that primer and that the explosive material not be detonated by the impact, inertia, heat or other conditions of bullet firing at any time before impact. Most commercial gun powders of present day commerce that have been tried have been found to function in my invention whether of the black powder or smokeless variety. Depending upon particular powder characteristics, energies and results desired, some are more efficient than others.

Most commercial gun powders of present day commerce that have been tried have been found to function in my invention whether of the black powder or smokeless variety. Depending upon particular powder characteristics, energies and results desired, some are more efficient than others.

Que tiene que ver la patente con lo que comentamos arriba?
La gente diariamente registra patentes para artículos esotéricos e inservibles, sólo un pequeñísimo porcentaje de estas patentes generan artículos que tienen éxito. Incluso si en principio parece una buena idea muchas veces hay problemas de costo, producción, mercadeo, tests en la vida real, etc.

Me llama la atenciòn el "si explotan o no explotan"... le acaba de pegar una .22 o .25 en el estomago del malandro... y uno se pregunta "exploto o no exploto".. aunque el fulano este tirado revolcado del dolor... ora nomas subanle el calibre a ver si es o no determinante este detalle de la balita! =)
