5. 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=.000046(T) The formula to find the imbalance is E=.000046(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 www.google.com/images/imbalanceof abullet

6. 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//www.google.com/fingerprints
