Munna bhai Medical Detective 007
Now it should be clear from the last post that, what a0.45 or 0.32 etc revolver means , it describes the calibre (see below), of that weapon.
In the Smooth bored firearms Shotgun is the most popular , where the barrel is long and not grooved inside. It is used for covering a wide area damage. Here the bullet used , contains, lots of small pellets, rather than one single projectile. As the barrel is smooth, after exiting, these pellets disperse in all direction after some distance. So this dispersion causes damage to a wide area covered by the pellets.
The impression of pellet on the victim's body the distance from which fire was shot, can be calculated.
The diagrammatic illustration will clear the things better. Let me show you.
