If you use Win. ammo and want to know what your bullet is doing or how much its dropping this chart will help, just type in the caliber and type of ammo.

Couple of questions about this first what is the difference between long and short trajecory and also is the zero plane the rifle barrel? thanks

RE: Ballistics chart from Winchester.
 

The Winchester charts I've reviewed have the short trajectory zeroed at 100 yards, the long trajectory at 200 yards.

nbguy, the zero plane would be where the rifle is set in at, in other words at what distance the bullet would hit to where the cross-hairs are, {ie either hitting dead on at a hundred yards or hitting dead on at 200 yards}.

The reason for both short and long trajectory info, is in reference for your zero and hunting conditions, meant as a guide for sighting in. (ie: your shots are usually 100 but might stretch to 200 it gives you +/- the zero point of 100 - this would be a short trajectory chart. Long chart may have a zero of 200 and give you +/- out to 400 or 500...used as a way to gauge bullet path or drop of given zero with the particular bullet and different ranges you may encouter...it also gives you speed(FPS) and energy (LBS)...to assess effective kill energy and time of travel(FPS)) This is really only meant as a guide, not rule...if you plan on take 100, 200 & 300 shots the best way to know for sure what your gun and bullet will do is shoot those distances and adjust the scope's zero accordingly...but it will get you close.

As stated zero plane is the part where the bullet cross the sight line and acheives a zero POI(point of impact). (Think of the bullet path as an arc...zero plane is where it crosses the sight line or zero mark. ie: dead on at 100 yards...before is + and after 100 will be -.
