What is teflon coated bullets?

Teflon coated bullets, also known as KTW bullets, are bullets that have a slick coating of Teflon applied to the outer surface. The intention behind using Teflon coating is to reduce friction between the bullet and the barrel of the gun, allowing for increased muzzle velocity and improved accuracy.

Despite popular belief, Teflon coating does not enhance the penetrating power of the bullet or make it "armor-piercing." In fact, Teflon coated bullets were banned by the Geneva Convention in 1899 due to concerns that the coating could damage the rifling of the barrel and increase the risk of ricochets.

Teflon coated bullets are sometimes used by law enforcement and military personnel for specialized tactical purposes, but they are not widely available to civilians. They are illegal in many jurisdictions due to their potential to cause harm or inflict serious injury.
