HOW A BULLET GETS ITS TWIST A gun barrel is produced from a solid bar of steel. The inner surface is impressed with spiral grooves which is know as rifling.

IMBALANCE OF A BULLET Many things can cause a bullet to be imbalanced. Many things can cause a bullet to be imbalanced. The formula to find the imbalance is E= (T) The formula to find the imbalance is E= (T) T is the twist rate and E is the amount of imbalance to cause one MOA divergence T is the twist rate and E is the amount of imbalance to cause one MOA divergence abullet

FINGERPRINTING: AFIS SYSTEM AFIS system is the ability of a computer system to scan and digitally encode fingerprints so they can be processed. Before this program police were restricted to comparing crime scene fingerprints against those of know suspects. http//
