<P> The shot is usually fired from a smoothbore barrel; another configuration is the rifled slug barrel, which fires more accurate solitary projectiles . </P> <P> The typical use of a shotgun is against small and fast moving targets, often while in the air . The spreading of the shot allows the user to point the shotgun close to the target, rather than having to aim precisely as in the case of a single projectile . The disadvantages of shot are limited range and limited penetration of the shot, which is why shotguns are used at short ranges, and typically against smaller targets . Larger shot sizes, up to the extreme case of the single projectile slug load, result in increased penetration, but at the expense of fewer projectiles and lower probability of hitting the target . </P> <P> Aside from the most common use against small, fast moving targets, the shotgun has several advantages when used against still targets . First, it has enormous stopping power at short range, more than nearly all handguns and many rifles . Though many believe the shotgun is a great firearm for inexperienced shooters, the truth is, at close range, the spread of shot is not very large at all, and competency in aiming is still required . A typical self - defense load of buckshot contains 8--27 large lead pellets, resulting in many wound tracks in the target . Also, unlike a fully jacketed rifle bullet, each pellet of shot is less likely to penetrate walls and hit bystanders . It is favored by law enforcement for its low penetration and high stopping power . </P> <P> On the other hand, the hit potential of a defensive shotgun is often overstated . The typical defensive shot is taken at very close ranges, at which the shot charge expands no more than a few centimeters . This means the shotgun must still be aimed at the target with some care . Balancing this is the fact that shot spreads further upon entering the target, and the multiple wound channels of a defensive load are far more likely to produce a disabling wound than a rifle or handgun . </P>

Is a rifle the same as a shotgun
