Following the flight way of a slug can give critical subtle elements amid a legal examination, in particular from what heading the shot was discharged. This is regularly imperative in remaking the arrangement of occasions all through an occurrence. Building up the way of a slug may not be direct, as various elements must be contemplated. Air resistance and gravity influence the projectile's flight way, making it anticipate in a descending bend instead of a straight line. Natural conditions, for example, solid winds could moreover somewhat adjust a slug's flight. How a shot's flight will be influenced will rely on upon the starting speed of a projectile, as those with a higher speed will be less affected, and in addition the state of the slug. Various elements can bring about unusual shot flight qualities.

Tumbling is a marvel identifying with flight lopsidedness, created when a slug is subjected to inadequate rifling or has been harmed. Another issue is 'yaw', an impact alluding to a slug's deviation from a straight way. This can be brought on by faulty rifling, poor stacking or a gravely cast shot. The decision and stacking of shot can likewise bring about issues. In the event that the client of the gun stacks the weapon with a projectile of wrong gauge, the shot may not accomplish a twist rate that will guarantee solidness, bringing about intemperate bore contact which eventually prompts a low gag speed. Mistaken shot decision can likewise prompt an extreme bore speed, bringing on the slug to slide over projectile rifling thus bringing about a low turn rate.
