This means that all the kinetic energy from the bullet is transferred into the target in a very short period of time. The most common application of this bullet is the shooting of vermin, such as prairie dogs. The effect of these bullets is quite dramatic, often resulting in the animal being blown apart upon impact. However, on larger game fragmenting ammunition provides inadequate penetration of vital organs to ensure a clean kill; instead, a "splash wound" may result. This also limits practical use of these rounds to supersonic (rifle) rounds, which have a high enough kinetic energy to ensure a lethal hit. The two main advantages of this ammunition are that it is very humane, as a hit almost anywhere on most small vermin will ensure an instant kill, and that the relatively low mass bullet fragments pose a very low risk of ricochet or of penetrating unintended secondary targets. Fragmenting bullets should not be confused with frangible bullets (see below).
