 Device for reducing ammunition drag and ammunition for receiving said device - Patent 4807535   (Site not responding. Last check: 2007-11-03)
A device for reducing drag of a round of ammunition or projectile (1) comprises a gas-producing compound (3) such as a propergol, the combustion of which generates gases at a pressure of at least sufficient value to fill the low-pressure region which is formed at the rear end of a projectile and causes drag.
An ammunition system according to claim 1, said closed rear end of the projectile comprising a hollow base (1a), said leak-tight cover (5) having a shape which is complementary to the internal surface of the hollow base (1a) of the projectile (1) so as to be capable of fitting within said base.
Thus in the case of a projectile such as a shell, it is possible to decide at the actual firing location whether it proves necessary or not to fit the device on the rear end of the projectile as a function of the desired range.

 Ammunition Summary
Ammunition is a generic military term meaning (the assembly of) a projectile and its propellant.
The corrugated cases are stacked in layers in the magazine with the mouth of the case towards a passage between the stacks, so that it can be opened and the cartridges removed and transferred to a leather case when required for transport to the gun.
Naval ammunition is therefore optimized for great velocity (to reach those great ranges, to hit aircraft flying at altitude and also with the benefit of reducing the lead that has to be applied to hit a distant moving target) and to disable said machines, rather than rending human flesh.

 Ammo Coding :: About Us
ACS assigns a unique code to every round of ammunition manufactured, and by recording sales records, law enforcement personnel will be able to easily trace the ammunition involved in a crime and have an avenue to pursue and solve even the most difficult cases.
Code is identifiable in cases where as little as 20% of the base of the bullet is recovered.
Ammunition retailers will scan the bar code on each box of bullets along with the purchaser’s driver’s license or state issued ID. The resulting electronic record would be transferred to a secure computer database that would confidentially maintain individual ammunition sales information.

 Extraction Problems
In the case of the lacquered ammo, as the chamber heated up, some of the lacquer melted and made the chamber into a sticky gooey mess.
If you are using ammunition that is not coated with lacquer and you are having problems with extraction, it is likely that it is slightly too large, the chamber is tight or a combination of both.
If an ammunition manufacturer tends to make ammunition that is on the large side of the tolerance range and the chamber manufacturer creates chambers that are on the smaller of the tolerance range, ammunition can get stuck in the chamber.

Extractor/ejector markings on the primer end of a shell casing: In the case of a revolver, when a round of ammunition has been fired, the bullet is propelled out of the firearm barrel and the empty cartridge casing remains within the firearm barrel until removed by the firearm user.
The theory behind the entry of newly manufactured or sold handguns is that the markings on a fired bullet or an empty cartridge casing found at a crime scene could be compared to markings in the database, thus identifying the handgun used by the criminal.
