   Exterior Ballistics
  I am currently attempting to handle various effects present on bullets during flight.  I have a fairly basic method in place using some simple bullet coefficient based drag models i found, but I am looking to find out more concrete informationon on handling the different characteristics of bullets and environmental factors that contribute to the way a bullet reacts when fired.  I currently use a G1 drag function combined with gravity and a simple calculation for relative wind interference and combine the forces with the initial/current muzzle velocity and trajectory direction over time to compute the change in state as the bullet travels.  I would like to find more information on how various ballistics calculators/simulations handle things like wind, altitude, temperature, bullet weight, ballistics coefficient, sighting, and other factors when computing the effects on a bullets trajectory in order to improve my current simulation.  How is this traditionally handled in more realistic simulations and related situations?Any information, resources, and/or advice you could provide would be greatly appreciated.Thanks in advance.   
  Although I don't know much about this field, I think you should probably take into account the fact that bullets spin. This probably keeps their trajectory more straight because of gyroscopic effects, but I don't think I can help you with the details. It may also help fight the bias introduced in the trajectory by asymmetries in the bullet's geometry.   ;  A bit of a wild card here, but have you ever played COD4? There is a mission of a sniper, and the bullet moves in the wind and the corrolis effect is taken into consideration. May be worth watching for ideas, bound to be a video on youtube (type: COD4 sniper mission).JamesCobras
