An Overview of Forensic Ballistics Ankit Srivastava, Ph.D. Assistant Professor Dr. A.P.J. Abdul Kalam Institute of Forensic Science & Criminology Bundelkhand University, Jhansi – 284128, UP, India E-mail: [email protected] ; Mob: +91-9415067667 Ballistics Ballistics It is a branch of applied mechanics which deals with the study of motion of projectile and missiles and their associated phenomenon. Forensic Ballistics It is an application of science of ballistics to solve the problems related with shooting incident(where firearm is used). Firearms or guns Bullets/Pellets Cartridge cases Related Evidence Bullet holes Damaged bullet Gun shot wounds Gun shot residue Forensic Ballistics is divided into 3 sub-categories Internal Ballistics External Ballistics Terminal Ballistics Internal Ballistics The study of the phenomenon occurring inside a firearm when a shot is fired. It includes the study of various firearm mechanisms and barrel manufacturing techniques; factors influencing internal gas pressure; and firearm recoil . The most common types of Internal Ballistics examinations are: ✓ examining mechanism to determine the causes of accidental discharge ✓ examining home-made devices (zip-guns) to determine if they are capable of discharging ammunition effectively ✓ microscopic examination and comparison of fired bullets and cartridge cases to determine whether a particular firearm was used External Ballistics The study of the projectile’s flight from the moment it leaves the muzzle of the barrel until it strikes the target. The Two most common types of External Ballistics examinations are: calculation and reconstruction of bullet trajectories establishing the maximum range of a given bullet Terminal Ballistics The study of the projectile’s effect on the target or the counter-effect of the target on the projectile. -

HOW to LOAD COWBOY FAST DRAW CARTRIDGES By: Cal Eilrich A.K.A
HOW TO LOAD COWBOY FAST DRAW CARTRIDGES By: Cal Eilrich a.k.a. Quick Cal, Executive Director CFDA Revised: November 27th, 2016 In 2007, we began researching various methods used to load Cowboy Fast Draw Cartridges for CFDA Titled Championship events. Everyone seemed to have their own formula. Some loaded them by hand and some loaded them on progressive loading presses. We found a wide variety of results, some even within the same tournament in which there was found 300+ (fps) variations in velocities. This meant that championships could have been decided because of ammunition variations of as much as 2 hundredths of a second (.020), which is a huge amount of time in Cowboy Fast Draw. We simply had to do better. In reality there will always be some variations in velocities even in factory live ammunition, at 15 – 20 fps. Bullseye shooters use techniques such as matched brass, matched bullets and a trickle powder charge to get it tighter than that. We also have to keep in mind that wax bullets, due to density variances, can never be manufactured and sized as exact as lead or jacketed bullets can be. After extensive testing, we have found that it is possible to reduce the velocity variances to around 30 – 40 fps, which only amounts to a few thousandths of a second. This is true with both CFD Cartridges and Shotgun Primer Loads. This article is about addressing, not only various components, but also loading techniques, and the best equipment used to load them. • Brass • Brass is the first step in producing consistent cartridges, make sure that you tumble them thoroughly, before removing the primers. -
Dictionary of Explosives
DICTIONARY OF EXPLOSIVES BY ARTHUR MARSHALL A .C .G j., F.I.C., F.C.S. CHEMICAL INSPECTOR INDIAN ORDNANCE DEPARTMENT PHILADELPHIA P. BLAKISTON’S SON & CO. 1012 WALNUT STREET 1920 Printed in Great Britain INTRODUCTION It is a generation since a dictionary of explosives has been published, and, in the meantime, many new explosives have been introduced. It is hoped, therefore, that this small volume, giving concise information about these special materials, may prove useful to those who have to deal with them. In Cundill and Thomson’s “ Dictionary of Explosives,” issued in 1895, there arc many entries of the names of inventors and of mixtures which had been proposed but have never been used commercially, nor are likely to be. As modem explosives were then in their infancy, it was no doubt wise to insert all the available information whether it appeared to be important or not; but now it seems to me better to restrict the scope of the dictionary so as to keep its size within moderate limits. Practically only explosives with special or proprietary names are therefore dealt with here. For information concerning chemical substances, such as the nitro-toluenes and other nitro-compounds, reference should be made to the text-books on explosives and chemistry. A few words may, however, be said here about the nitro- celluloses. These are made by treating cellulose with a mix ture of nitric and sulphuric acids, and then purifying the product by washing it thoroughly with hot water. The variety of cellulose most used for this purpose is cotton, and the product obtained from it is frequently called nitrocotton, three special varieties of which are collodion cotton, pyro- collodion and guncotton (q. -

Internal Ballistics
Internal ballistics The term ‘Ballistics’ is derived from the Latin word “Ballista” which refers to a crossbow like device for throwing stone by means of twisted ropes. In order to understand elements of ballistics, it is divided into three parts as described below: 1. Internal ballistics 2. External ballistics 3. Terminal ballistics Internal ballistics is the study, which deals with the motion of projectile/s in the bore of the weapon whereas external ballistics deals with the fight from the muzzle of the weapon to the target. This, indeed is, terribly complicated subject involving parameters such as shape of the bullet, sectional density, atmospheric conclusions and even rotation of earth in larger-caliber weapons. With the advent of powerful personal computers the complex calculations have become quick and accurate. The terminal ballistics deals with the behavior of missile once it reaches the target such as wounding capabilities and includes its performance in water, soil, brick, concrete, wood and other bullet resistant materials. In order to understand the factors affecting the projectile in the barrel, certain terms need to be explain such as smooth bore weapons, rifled firearms, lock time, ignition time and barrel time etc. Shotguns and improvised firearms (country made) are smooth bore weapons and fire a spherical ball, slug or a charge consisting of a considerable number of lead pellets (shot) having spherical shape. They make a perfect circle at any point of cross section. A rifle has lands & groove as well as rifling marks. Rifled weapons fire bullets, which are not spherical in nature but elongated. Thus behaviour of projectiles inside the barrel in the two cases would obviously be different. -
