Ballistics Fmt Flashcards
Discharges from rifled gun?and their effects on body?
Flame -burning
Smoke-blackening
Unburned gp- tattooing
Bullet- puncture wound
Grease collor
Abrasion collor
Range of flame in rifled and shot gun?
8cm
15cm
How much distance Smoke can travel in both rifled and shot gun? What about gp?
15 cm
30cm
60-90cm
Detection of intermediate shot
Flame
Smoke
Gp
Bullet
How cruciate / stellate entry wounds are formed in a rifled gun ? And where it occur?
Tight contact shots.
On scalp by hot gas
Back spatter what is it? And in which gun it is seen?
Sucking of tissue by the vacuum created in the gun. In case bullet fired in tight contact.
Shot gun.
Explain wound fouling
Scrapped of metallic particle from bullet.
How u identify Entry wound?
Inverted
Burning, blackening, tattooing
Grease and abrasion collar
Small wound with less bleeding
More bleeding and spattering is seen with which wound?
Exit wound
What is the importance of Entry wound od CO poisoning
Cherry red skin
Mechanism of shored/ supported exit wound?
Resistance for bullet to exit, due to supported wall, the spinning bullet crush the skin and form abrasion wound
How you identity the firearm which is used to shot a person?
Crime bullet
Bullet fingerprint
GSR Test
Which marking in known as fingerprint of the bullet? And explain both the markings
Secondary marking.
Produced due to irregularities of barrel, varies from gun to gun and microscopic.
Primary : rifling groove, make and model of gun, same for the same models and macroscopic.
How the secondary markings are formed in a gun?
Wear & tear
Manufacturing defects
Metallic fouling (molten lead deposits inside the barrel )
Comparison microscope used to identity.
What is the importance of GSR test?
Fired by the accused.
Within 3 hrs.
Firing HANDS
WAD, how long it can travell and what does it cause?
2-5m
Minor contusion
Shot gun ranges and distance upto which they can travel??
Close, near, intermediate, distance
<1, 1-2, 2-4,> 4
When the dispersion of shot gun start? How long it can travel??
2m
4m
Does shot gun produces exit wound??
If yes,When they can produce one
Contact shot
Thin body part
Tangential shot
Piggy back bullet???
Gun not used for a long pd. Then 2 bullets back to back comes out, second time
What u call If trajectory of the bullet is irregular?
Yawning bullet
Bullet which rotate?
Tumbling bullet
Ricochet bullet ?? What is the angle?
How it differs from other bullets?
Bullet get deflected by hitting intermediate object. 10 -30° ricochet angle is needed.
No flame, smoke, gp.
No spinning, therefore no abrasion collar
Bullet might tumble andproduce atypical entry wound
Sleeping bullet?
Retained bullet in the body
Kennedy phenomenon?
Alteration in the wound
Rayalaseema phenomenon?
Inserting bullet in stab wound
Balling vs billiard ball ricochet effect
Far - intermediate(incomplete dispersion )
Near-far( erratic dispersion )
Kronlein shot?
Contact shot of skull
Expansion of gases
Sudden expulsion of brain parenchyma
Maganstrasse
Acid
Lesser curvature
