Holowpoints & Softpoints in Combat

Well, it was bugging me, so I looked a couple things up:

In the field of firearms, an expanding bullet is a bullet designed to expand on impact, increasing in diameter to limit penetration and/or produce a larger diameter wound. There are many expanding bullet designs, though the most commonly encountered are the hollow point bullet and the soft point bullet.

Such bullets are sometimes known as Dum-dum or dumdum bullets, after an early British example produced in the Dum Dum Arsenal, near Calcutta, India by Captain Neville Bertie-Clay.[1][2]. There were several expanding bullets produced by this arsenal for the .303 British cartridge, including soft point and hollow point designs. These were not the first expanding bullets, however; hollow point expanding bullets were commonly used for hunting thin skinned game in express rifles as early as the mid 1870s.[3]. The use of the term "Dum-dum", applied to expanding bullets other than the early .303 designs, is considered slang by some.[4] Manufacturers have many terms to describe the particular construction of the various types of expanding bullets, though most fall into the category of soft point or hollow point designs.
[edit]History

Early bullets were typically made in the form of spheres of nearly pure lead, which is a very soft material. These would often flatten upon impact with the target, causing a larger wound than the original diameter of the ball. The adoption of rifling allowed the use of longer, heavier bullets, but these were still typically constructed of soft lead and would often double in diameter upon impact. In this case expansion was a side effect of materials, and there is no evidence that the bullets were designed to expand upon impact.[5]
The earliest examples of bullets specifically designed to expand on impact were those fired by express rifles, which were developed in the mid 19th century. Express rifles used larger powder charges and lighter bullets than typical for the time to achieve very high velocities for black powder cartridges. One method of lightening the bullets used was to provide a deep cavity in the nose of the bullet. These were the first hollow point bullets, and in addition to developing higher velocities, they also expanded significantly upon impact. These hollow point bullets worked well on thin-skinned game, but tended to come apart on bigger game, resulting in insufficient penetration. One solution to this was the "cruciform expanding bullet", a solid bullet with an X shaped incision in the tip. This split section expanded to the depth of the incision, and then stopped, making it an early form of controlled expansion bullet.[6]
In the late 19th century, the invention of Cordite and other nitrocellulose based "smokeless" propellants permitted higher velocity than black powder, along with flatter trajectories and correspondingly higher hit probabilities. However to limit the amount of recoil to an acceptable level meant that higher velocity rounds needed lighter (and thus smaller diameter) bullets.
Soon after the introduction of smokeless powder to firearms, full metal jacket bullets were introduced to prevent lead fouling in the bore caused by the higher pressures and velocities when used with soft lead bullets.[7] However, it was soon noticed that such small caliber rounds were less effective at wounding or killing an enemy than the older large caliber soft lead bullets. Within the British Indian Army, the Dum Dum arsenal produced its now infamous solution - the jacketing was removed from the nose of the bullet, creating the first soft point bullets. Since the Mark II jacket did not cover the base of the round this could potentially lead to the jacketing being left in the barrel. This potential problem resulted in the rejection of the Dum-dum design, and independent development of the Mark III, Mark IV (1897) and Mark V (1899) .303 British rounds, which were of the hollow point design, with the jacket covering the base; while these were made in Britain, not at the Dum-Dum arsenal, the name "Dum-dum" had already become associated with expanding bullets, and continued to be used to refer to any expanding bullets. The expanding bullets expanded upon impact to a diameter significantly greater than the original .312 inch (7.62 mm) bullet diameter, producing larger diameter wounds than the full metal jacketed versions. The Mark IV was successful enough in its first use at Omdurman that British soldiers issued with the standard Mark II bullets began to remove the top of the jacket, converting the Mark II bullets into improvised Dum-dum types.[8]
In 1898, the German government lodged a protest against the use of the Mark IV bullet, claiming the wounds produced by the Mark IV were excessive and inhumane, thus violating the laws of war. The protest, however, was based on the comparison of the wounds produced by expanding and non-expanding bullets from high velocity sporting rifles, rather than a comparison of the expanding .303 British bullets with the previous, large bore service cartridge it replaced, the .577/450 Martini-Henry.[9] Because the energy was roughly the same, the wounds caused by the expanding bullet of the .303 were less severe than the those caused by the larger caliber, solid lead bullet used by the Martini-Henry.[10]
The German protests were effective however, resulting in the ban of the use of expanding bullets in warfare. The British replaced the hollow point bullets with new full metal jacket bullets, and used the remaining stocks of expanding bullets for practice.[11]
[edit]Law

The Hague Convention of 1899, Declaration III, prohibits the use in international warfare of bullets which easily expand or flatten in the body, giving as example a bullet with a jacket with incisions or one that does not fully cover the core.[12] This prohibition was an expansion of the Declaration of St Petersburg in 1868, which banned exploding projectiles of less than 400 grams. During the Convention, representatives from Imperial Germany provided evidence of severe expansion in flesh, however these experiments were severely criticized by the British because they used higher powered German sporting cartridges with expanding bullets, and compared results only to the earlier, non-expanding .303 bullets. No comparison was made with the terminal effects of the non-jacketed, large bore bullets used just a few decades before by militaries around the world, such as the .577 caliber (14.7 mm) Snider-Enfield and the .45 caliber (11.4 mm) Martini-Henry which the .303 replaced.[13]
Because of the greater effectiveness in disabling or killing the target, the use of expanding rounds remains legal, or even required, in some circumstances. Examples of this are use of appropriately expanding bullets in hunting, where it is desirable to stop the animal quickly either to prevent loss of a game animal, or ensure a humane death of vermin, and in law enforcement or self defense, where quickly disabling an aggressor may be needed to prevent further loss of life.[14][15]

There fixed it for ya. (can't stand blue):)
 
blackpowder rob -

I noticed you left out the link to some detailed info

About the Hague Convention.

Was that because it was in black?

Contained within that link:

"Laws of War :
Declaration on the Use of Bullets Which Expand or Flatten Easily in the Human Body; July 29, 1899
The Undersigned, Plenipotentiaries of the Powers represented at the International Peace Conference at The Hague, duly authorized to that effect by their Governments,

Inspired by the sentiments which found expression in the Declaration of St. Petersburg of the 29th November (11th December), 1868,

Declare as follows:

The Contracting Parties agree to abstain from the use of bullets which expand or flatten easily in the human body, such as bullets with a hard envelope which does not entirely cover the core, or is pierced with incisions.

The present Declaration is only binding for the Contracting Powers in the case of a war between two or more of them.

It shall cease to be binding from the time when, in a war between the Contracting Parties, one of the belligerents is joined by a non-Contracting Power.

The present Declaration shall be ratified as soon as possible.

The ratification shall be deposited at The Hague.

A proces-verbal shall be drawn up on the receipt of each ratification, a copy of which, duly certified, shall be sent through the diplomatic channel to all the Contracting Powers.

The non-Signatory Powers may adhere to the present Declaration. For this purpose they must make their adhesion known to the Contracting Powers by means of a written notification addressed to the Netherlands Government, and by it communicated to all the other Contracting Powers.

In the event of one of the High Contracting Parties denouncing the present Declaration, such denunciation shall not take effect until a year after the notification made in writing to the Netherlands Government, and forthwith communicated by it to all the other Contracting Powers.

This denunciation shall only affect the notifying Power.

In faith of which the Plenipotentiaries have signed the present Declaration, and have affixed their seals thereto.

Done at The Hague the 29th July, 1899, in a single copy, which shall be kept in the archives of the Netherlands Government, and of which copies, duly certified, shall be sent through the diplomatic channel to the Contracting Powers.

[Signatures]"


Note: Only the signatories to this Convention must abide

By the type of ammunition described within...........

I don't really think it would change anything.

If I shoot someone with M855 ball out of my M249, I'm going to shoot him five or six times on the principle that anyone worth shooting is worth shooting repeatedly. Not sure if an expanding bullet would really make a difference there.
 
I know quite a few guys that pooled their cash together and bought 1911's, and they are over there fighting as we speak.

YaNi,

I find it interesting to note that that you don't actually say these "guys" TOOK personally owned weapons with them. But I'd love any form of documentation if you're trying to make such a claim.

---

Per individual round, expanding bullets are more effective. In actual usage by US troops, since SOP is at least two rounds to target, there probably would be little perceived difference. As for our enemies, it's hard enough for them to get FMJ. Getting decent expanding rounds would be a supply issue.
