Of this rotation results in a shift of impact point to the right (compared to We only need two components because we are not shooting directly away from theĮarth for great distances as would a missile for example. Shift in the target position while a projectile is in flight. There are three components to the Coriolis Effect which accounts for the apparent Observer at the North Pole sees the earth as rotating counter-clockwise. Object located on a latitude line which is parallel to the equator. Rotation, objects in both hemispheres rotate with the earth from west to east.Īn observer at the South Pole sees the earth as rotating clockwise based on an The previous paragraph we mentioned the Coriolis Effect. It is a complete and thorough stand-alone Although we use Nightforce scopes for target shooting, their The Nightforce ballistic program covers all of the variables mentionedĪbove and more. You have a powerful argument for purchasing and using a commercial ballistic Save your work with online programs, problems with printing out the results and Provision for sight adjustment specifications, spin drift calculations, CoriolisĮffect, or ballistic reticle analysis. Most required you to obtain the ballistic coefficient of Our family started shooting in F-Class competition, we realized that a commercialīallistics program was necessary. The free online ballistics programs were quite sufficient. Pounds of energy for our “pet loads” or determine bullet drop at various ranges, The few times that we wanted to determine the foot That technique worked quite satisfactorily with factory ammunitionĪs well as our own reloads. It was relatively easy with a boresighter to get ourīullets on paper at 100 yards and then “walk” the load into the bullseye with aįew shots. We used the Hodgdon’s Reloader’s Manual for all information We were primarily hunters and didn’t need all the features of commercial Years we never used a ballistics program or saw the need to buy one.
