Ricochet Analysis Introduction

Projectile Ricochet

When a bullet strikes any surface, there is a critical angle at which the bullet will bounce off or ricochet from the surface rather than penetrate. After ricocheting from the surface, the missile will lose a considerable amount of its velocity anything up to 35 in test firings and, invariably, lose its stability. This is contrary to the popular belief that a ricocheting bullet will carry further than one fired at the elevation for maximum range. The actual degree at which a bullet will...

Cycles Of Functioning

M16 Bolt Override

The soldier must understand the rifle components and the mechanical sequence of events during the firing cycle. The eight cycles of functioning feeding, chambering, locking, firing, unlocking, extracting, ejecting, and cocking begin after the loaded magazine has been inserted in the weapon. a. Feeding Figure 4-3, page 4-4 . As the bolt carrier group moves rearward, it engages the buffer assembly and compresses the action spring into the lower receiver extension.

Penetration potential

The penetration of various materials can be of great assistance in the investigation of shooting incidents. It is also of considerable general interest if for no other reason than to show how often the movie makers and novel writers make appalling blunders. In the past, one of the standard tests performed to assess bullet and cartridge performance was the penetration of pine boards of various thicknesses. This, as with any other type of penetration test, is plagued with inaccuracies. Many...

Brief History of Forensic Firearms Identification Introduction

As with any evolving science, the exact origins of forensic firearms identification are shrouded in obscurity. Exactly when it was first noted that fired bullets from a given weapon possessed a certain number of equally spaced impressed grooves, all inclined in the same direction and at the same angle, and which were the same on every other bullet fired through that weapon, will probably never be known. Likewise, it will never be known when the next logical step was taken to compare the width,...

Nontoxic and frangible bullets

Lead contamination of firing ranges, both indoor and outdoor, has been a continuing and serious problem. The US National Bureau of Standards claims that 80 of airborne lead on firing ranges comes from the projectile, whilst the remaining 20 comes from the combustion of the lead styphnate primer mixture. In the early 1980s, a concerted move was made towards eliminating this health hazard, especially at training facilities and indoor ranges. The first step in this process was to eliminate the...

Methods of measuring barrel pressure

Homemade Guns And Homemade Ammo

Assuming that the weapon is in good condition and that the correct type of ammunition is being used, it is the pressure produced in the barrel which ultimately decides whether the bullet will either reach the muzzle, exit from the barrel at an acceptable velocity or destroy the weapon completely. Often weapons are received with reloaded or home- made ammunition and for safety sake, it is often necessary to determine whether the ammunition is in fact safe to fire. At other times, it is necessary...

Headstamp Markings on Ammunition Introduction

Bmg Headstamps

A cartridge headstamp is a mark, or series of marks impressed, or sometimes embossed, on the head of the cartridge case during its manufacture. The mark can consist of numbers, letters, trademarks, figures or any combination of these. Systems of headstamp markings are used worldwide. They can be in any language, numbering system or can relate to any calendar. From these impressions, one can, depending on the type of ammunition and its origin, determine the manufacturer, calibre, type, date of...

Priming Compounds and Primers Introduction

A priming compound is a highly sensitive explosive chemical which, when struck by the firing pin or hammer of a weapon, will explode with great violence, causing a flame to ignite the propellant. This explosive chemical is often mixed with other chemicals which provide oxygen to assist in the production of the flame, a fuel to increase the length and temperature of the flame and ground glass as an abrasive to assist in the initial ignition of the explosive. In the realms of forensic science,...

Firearms And Fingerprints In The Crime

Firearms Transfer Thumbprint Card

The roles of firearms and fingerprint examiners in the crime laboratory are numerous and varied. Firearms examiners are frequently called upon to do many things that do not fall under the traditional heading of firearms identification. Examples include serial number restoration with chemical etchants, gunshot residue analysis for barium nitrate, and shooting incident reconstruction. Similarly, fingerprint examiners must be proficient in specialized methods of photography, the application of...

Recovery methods for fired bullets

If a weapon has been recovered, it will be necessary to compare fired ammunition from this weapon with fired ammunition recovered from the scene. Obtaining a series of test cartridge cases from a self-loading pistol presents little difficulty as they merely have to be picked up. Obtaining fired bullets in a near pristine condition is, however, a little more difficult. In the past, cotton waste or wadding has been used, but this material can be quite abrasive to soft-lead bullets especially...

Llama Pistol Identification

Gun Cross Section

Automatic pistols made by Gabilondo from 1914 to 1933 were based on Browning F.N. models of 1903, 1906, 1910, and 1922. In 1931 it was decided to modernize their line by undertaking the manufacture of the external hammer, recoil-operated system originally designed by Browning and used by Colt and the Fabrique Nationale. Work on a new design began in 1931 and culminated in 1932 with a Spanish patent issued on April 12th of that year. The first pistol produced was an exact copy of the Colt Mod....

Disassembly of the Bolt for Cleaning and Inspection

Lee Enfield Disassembly Bolt

The bolt head can be unscrewed from the bolt body. This facilitates cleaning and inspection. The removal of the firing pin can be difficult. However, with the proper tool, it is a simple procedure for the person with some mechanical dexterity. With the bolt head removed, look at the front of the bolt and you wil see the two notches on both sides of the firing pin shoulder. Insert the t-shaped tool into the notches and turn the cocking piece until the lower two notches are reached. The firing...

Spanish Firearms Manufacturers

Firearms identifications are of interest to those engaged in law enforcement and to gun collectors, but from quite different points of view. The law enforcement officer is chiefly concerned with bringing to justice persons who have committed crimes, while the collector is interested in guns because of a fascination that only a gun collector can fully understand. Both need to know all that they can learn about firearms and it is hoped that the material here presented will be useful to both...

Hammer Design For Falling Block Rifle

The hammer of the No. 1 VAULT LOCK is readily cocked with either the thumb or forefinger. If the hammer is cocked by the thumb it is best done by starting the cocking action with the side of the thumb and once you become adept at it, it can be done in one motion without difficulty although you may want to roll your thumb so that at the end of the swing the tip of your thumb pad does the final cocking. Some shooters using this rifle prefer to use the index finger to cock the hammer. In any case...

Falling Block Rifle Plans

For many years a dream of mine was to design and build a non-bolt action single shot rifle I could call all my own. That dream was slow in being fulfilled and 1 kept telling myself I had good reasons for putting it off. Anyway, my dream action had to be different from all others and it had to be of simple design and construction, but most of all it had to be one I could make in my modestly equipped home workshop. It was the late John Amber, who edited my book Single Shot Rifles and Actions, who...

High Standard pistols

The presently named High Standard Manufacturing Corporation, of Hamden, Conn., started out in 1926 as the High Standard Manufacturing Company, in New Haven, Conn., when C.G. Swebilius and three other men began the manufacture of gun barrel drills. At that time the firm had three employees. In 1932 the firm acquired the Hartford Arms and Equipment Co., of Hartford, Conn. This firm had developed and produced a single-shot pistol, a repeating pistol, and an automatic pistol. Although this firm was...

Bullets without Rifling Marks

Rifling Marks

Occasionally a bullet recovered at autopsy will show no rifling on its surface. Lack of rifling indicates that the weapon is a zip-gun, a smooth-bore handgun, or rifle, or a revolver whose barrel has been removed. Zip guns have been previously discussed. Weapons intentionally manufactured with smooth-bores are almost all .22-caliber rifles made for the exclusive use of .22 shot cartridges. Rarely, weapons that are supposed to have rifled barrels, inadvertently, get out of a factory with smooth...

303 Enfield Rifle How Safety Catch Works

Lee-Enfield rifles introduced in 1888 were in use throughout the British Empire from then until 1951, when they were gradually phased out. By 1957, Great Britain had switched to the .308 or NATO caliber. In the constantly changing world of military arms, 63 years is a very long lime for one rifle to remain the number one battle rifle. As a comparison, the ubiquitous Mauser 98 was introduced in 1888, but did not come on the scene as the 98 until 1898. The secret of the Lee- nfiet lt fs staying...

Longrecoil mechanisms

M249 Ejecting The Cycle Operation

The need for the entire barrel bolt unit to recoil a considerable distance, followed by a delay in commencing reloading while the barrel returns into the firing position, gives long-recoil mechanisms a relatively low rate of fire. As a result, weapons using this system are much less common than the short-recoil type. However, the long and relatively soft recoil push puts less strain on the mechanism and makes accuracy easier to achieve while avoiding the need for the whole gun to recoil in its...
