Lansing police officers say they believe the Washington D.C. sniper used a .223 caliber bullet to shoot his victims. They say that bullet is extremely accurate and powerful.
According to Sgt. Steve Relyea - a police officer for 20 years - a shooter with little experience could fire the bullet from 400 to 500 yards and still hit an intended target fairly accurately.
Police say the .223 caliber bullet works with several types of guns weapons because a variety of people use the bullets including police, civilian marksmen and hunters.
When the bullet is traveling at extreme velocities it can cause severe damage. Sgt. Relyea says the bullet will leave a small hole in the victim, and because it is traveling so fast, it can tear through and destroy internal tissue when it enters the body.
