Presentation Ballistics
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. -

Barnes Bullets ~ 2008 ~ a Respected Legacy of Commitment, Innovation, and Dedication
Barnes Bullets ~ 2008 ~ A respected legacy of commitment, innovation, and dedication. “It’s been 34 years since Coni and I purchased Barnes Bullets, and we’re proud of what we’ve accomplished,” said Randy Brooks, president of Barnes Bullets. “Our first products were the pure lead core, pure copper jacketed Barnes Originals Fred Barnes first manufactured in 1932.” Today, those bullets have been largely replaced by newer, improved versions of the revolutionary, 100-percent copper X Bullet Randy invented in 1986. Extremely popular with experienced shooters and professional hunters alike, these bullets have set new standards for accuracy and performance. Randy Brooks, president and co-owner (with his wife Coni) of Randy took this trophy desert mule Barnes Bullets, has a long family deer in Mexico with a .300 WSM heritage of hunting.

Randy and Coni Brooks have actively supported the shooting sports, donating both time and finances to industry organizations. They continue to develop innovative new products to improve their customers’ hunting success. -

Terminal Ballistics
Terminal ballistics Terminal ballistics, a sub-field of ballistics, is the study of the behavior and effects of a projectile when it hits its target.[1] Terminal ballistics is relevant both for small caliber pro- jectiles as well as for large caliber projectiles (fired from artillery). The study of extremely high velocity impacts is still very new and is as yet mostly applied to spacecraft design. 1 General An early result is due to Newton; the impact depth of any .32 ACP full metal jacket, .32 S&W Long wadcutter, .380 ACP projectile is the depth that a projectile will reach before jacketed hollow point stopping in a medium; in Newtonian mechanics, a pro- jectile stops when it has transferred its momentum to an equal mass of the medium. If the impactor and medium 2.1.1 Target shooting have similar density this happens at an impact depth equal to the length of the impactor. For short range target shooting on ranges up to 50 me- For this simple result to be valid, the arresting medium is ters (55 yd), aerodynamics is relatively unimportant and considered to have no integral shear strength. Note that velocities are low. As long as the bullet is balanced so it even though the projectile has stopped, the momentum is does not tumble, the aerodynamics are unimportant. For still transferred, and in the real world spalling and similar shooting at paper targets, the best bullet is one that will effects can occur. punch a perfect hole through the target. These bullets are called wadcutters. They have a very flat front, often with a relatively sharp edge along the perimeter. -
Firearms 101
Firearms 101 Shotgun Course and Rifle Muzzleloader Course have been combined into one all inclusive Firearms Course. Firearms Course now covers - Shotgun shooting - Rifle shooting - Airguns - Muzzleloaders Live Fire will only be done with the shotgun. New Course Completion Cards say “Firearm” - Will allow you to buy both a firearms hunting license and a rifle permit 1 Treat Every Firearm as if it were Loaded Treat every firearm as if it were loaded - Never accept a firearm from someone until they have proven it is unloaded - Safety is always ON. When does it come off? – When firearm is mounted on your shoulder and you know your target and what is beyond. - Do I use the scope as binoculars? No 2 Keep Muzzle in a Safe Direction Keep Muzzle pointed in a safe direction - What is a safe direction? A safe direction is always changing. - Need to be very aware of your surroundings anytime you have a firearm in your hand. - Two Hand Ready Position gives you best control of the muzzle 3 Be Sure of Your Target and Behind Know your target and beyond - .22 ammo = 1 mile - Shotgun slug = about 3600 ft - 00 Buckshot = about 1800 ft - Fine shot 500 – 900 ft - Distances above are with firearm pointed at optimum angle in the air. Projectile can ricochet even further - Should never shoot at a deer on crest of hill or bear in a tree. - Puts in perspective just how far a shotgun slug can go. - 450 ft Safety zone is not a ballistic cloak, but just a small buffer between us hunters and those that don’t hunt. -

Learning Outcomes After studying this module, you shall be able to know about- What is Terminal Ballistics What is penetration potential and the concept behind wound ballistics You will be also made familiar with the identification of entry wounds and the constructional features and wounding capabilities 2. Introduction Ballistics is the science involving study of motion of projectiles. The term Ballistics is derived from the Latin word “Ballistic” meaning a cross-bow like device for throwing stones by means of twisted ropes. When firing pin hits the primer, excessive heat is generated and the bullet (projectile) get pushed from the cartridge and start moving inside the barrel of a fire arm. This comes under the field of internal ballistics. The study of internal ballistics involves burning or combustion of grains of the propellants. The study is called internal ballistics so long as motion of projectile is inside the barrel of the weapon. As soon as the projectile leaves the muzzle end of the weapon the External ballistics comes into play and remain till the projectile hits the target. -
