As in, what is a PSD??

If you are interested in forming a Quad-.50 association, send your e-mail address to me at [email protected] Mention Quad-.50 in the subject heading. You'll hear from me when I get several responses. Messages to this forum welcomed. - Jim Lyons, former Quad-.50 gunner, U. S. Army, 1956-57.

The M14 fiers 7.62x51mm NATO, Soviet rounds are 7.62x39mm and 7.62x56mm Rimmed, they are not compatible..

In Iraq there ahs been terrorist that have been shot at within 20M with a 14.5 M4 about 10 times and have not been down. No shot will kill a person with only one shot in the chest ( Depends of shot place me... Head for example) The only way that you really can kill a person with one shot is with a .50 cal

can anyone tell the minimium velocity for the 5.56 round inorder for it to fragmate? is it 2700 FPS?

Best fragmentation at 2900fps, absolute minimum velocity for fragmentation 2750fps. Between 2500fps and 2750fps you get some rather significant yawing but no fragmentation without encountering a major solid mass (i.e. femur).

Still, if the bullet strikes a bone, even when at speeds as low as 2500fps, it will shatter it, and cause fragments of bone to cause immense damage even if the round itself does not fragment..

While the A-180 IS effective out to about 200 meters with HV 40 grainers or Stingers due to it's 2,200-2,400 RPM rate of fire, holding the bullet stream on target long enough to get the 8-12 hits required at those ranges is hard. It WOULD be very effective in built up urban fighting but it's lack of pennitraition of improvised and standard construction barracades is a detriment to it's addoption. I note two things that are realivant to this discussion. 1. In police shootings with soft point ammo, it is almost 100% effective at producing "one shot stops" with a very, very high lethality ratio. 2. The Hague and Geneva conventions technicaly do not apply to the War on Terrorism. Their rules and protections only apply to "Uniformed Combatants" in declaired conflicts. The above facts can eliminate ALL of the problems that have been layed at the feet of the 5.56 mm altar. The benifits of the 5.56 system are to many to list and worth the effort required to keep it. As a second thought, switching to a composit projectile like that used in the Ruski 5.45 mm round would also solve all of the above problems. P.S. The 5.56 was thought of as a good killer in RVN and was greatly praised for it's light weight.

While it is true that the vast majority of tests were underground, many of those underground shots did release significant amounts of radiation. Even if you discount the undergound test shots, the remainder of the remaining above ground "Atmospheric" test detonations out numbered the total number of test shots of ALL OTHER NATIONS EXCEPT THE FORMER SOVIET UNION! That modern weapons relice significantly less radiation than earlier types is also often ignored. ( The Hiroshima bomb released more radiation than 112 Air burst W-54's.) The Indians might not be able to detect the radiation from such an attack if they were not prewarned so that they could launch high altitude aircraft to sample it. Look at the history of Chernoble. The locals are still living with in yards of the fence around the place and they are not "Dropping like flies"! While I do not say that iradiation by any source is not dangerious, it is just that the danger is extreemly over blown! Burning coal for power releaces more total radio-nuclitides each year world wide than all the weapons tests to date combined! No one complains about the risk from that radiation poisoning, DO THEY? Finnaly, your reply does not address the fanaticle idiology that makes terrorism a viable method of forcing policy change in asymetric senarios. Untill those who view organised murder and terror as a viable policy realise that we are not only willing but eager to EXTERMINATE THEM AND THEIR CHILDREN this war will continue for generations. The use of Nuclear Weapons now would send that message loud and clear and in the long run, save tens or hundreds of thousands of lives. Finaly, the part of the Conventions on War that protect civilians and other non-combatants do not apply to criminals, some types of insurgents and TERRORISTS. The use of soft point ammunition against them is "specificaly permited" under several articles of BOTH of those Conventions. I recomend that you down load the Convention texts and articles were you could read them your self.

The "Biomass Energy Conversion" senario is one of the biggest frauds ever perpitraited on the public at large. The technology has existed since before WW-II when it was used extencivly in France and Germany. Look at fotos of the time. Any time you see a car with a torpedow like tank on the roof, that is what you are talking about. 1. Untill it is in wide scale comertial production so that the liquid product is available from gas station pumps, it is a non-starter. 2. It will never ever make the USA or any other country energy independant. 3. It is terrably in-efficiant. 4. It compeets with food production for Biomass that some think is waist. I.E. the stuff we do not eat is fed to cows and pigs. 5. The only viable replacement for focile fuels is nuclear power plants and lots of them. So that they can replace very efficiant oil as a motor fuel with electricity and all of its intendant in-efficiancies! Because of those deffects and lack of efficiancy, it takes about ten to twenty times more total electrical power to move your tiny little two person commuter car a mile than it takes oil energy in the form of gasoline to move your six pasenger Dodge or Ford the same distance. 6. If all oil production on the planet was privatised and forced to compete for customers, the price of oil would fall dramaticaly. 7. All other energy technologies that promice "Independance" are frauds or so defective in one way or another as to be of no practicle use. I can't wait to hear the howls about this post. So please do your reasearch before writing.
