jwp475, You "nailed it"! The bullet should have very high percentage of success reaching vital organs from any angle with a bullet of, adequate sectional density,good bullet construction,impact velocity, and correct shot geometry(bullet path in line with vitals). If the bullet cannot fullfill these requirements, we actually have two failures.The bullet (thru no fault of it's own) and operator error(improper bullet selection for application)! memtb
