The objective of the present study was to elucidate the objective signs and features of damages to the closing produced by shots fired from a 12-gauge hunting rifle with 'cylinder' and 'choke' muzzle threads that allow to determine the concrete distance of the injurious 'compact' and 'relatively compact' action of the multiple-element projectile (shotgun pellets) or that of the container wad used with regular cartridges.

The objective of the present study was to reveal the objective topographic and morphological features of entry holes in the cloths produced by the hunting smoothbore weapon shots from different distances using various ('cylinder' and 'choke') adjustable muzzle adapters and the regular cartridges loaded with shotgun pellets in a closing container wad and without it. The study has demonstrated the influence of the specific constructive features of the muzzle adapters and differently loaded cartridges on the mechanisms of damages caused by the gunshots from different distances.

The objective of the present study was to analyze the available information contained in the special literature concerning the possibilities for the expert assessment of the influence of the constructive and ballistic characteristics of hunting weapon barrels («cylinder¼ versus «choke¼) and their regular ammunition (equipped with pellets placed in a special wad-container and without it) on the mechanisms of damage formation. It was shown that the barrel muzzle narrowing produces the well apparent effect on the process of formation and release of all the damaging factors of the shot which makes it difficult to diagnose the resultant damage. It is concluded that the use of shooting ammunition with the pellets enclosed in wad-containers creates the objective prerequisite for the differentiation between its different types.
