I am a long way from a computer expert, so I was hoping some one would figure this out for me. Here are the parameters.
The cartridge I am shooting is 6.5X284. The bullet is a Lapua Scenar. The weight is 108 grains. Sectional density: .221
Ballistic coefficient: .478 My Muzzle Velocity is approximately 3300 fps(not chronographed). I have the rifle zeroed at 200 yards. I was wondering if some one knows how to figure the ballistics of this load?
First I was wondering what the trajectory is with a 200 yard zero? Second I was wondering what my trajectory would be with a 300 and a 400 yard zero. Third I wonder how high I would be at 100 yards when I have a 300, 400, and 500 yard zero.
I am trying to determine what my scope settings should be at 100 yards so that I can dial in at 300, 400 and 500 yards. I realize there is no fast answer, and all settings will have to be shot at the bench. I am only trying to have some simple comparisons to begin with.
I have zero experience with computer ballistic charts, and I was hoping that someone has alot of experience with computer ballistics, and this would be a simple exercise for them? Thanks, Tom.

There is the program I use to figure out my trajectorys when working up new loads. Works well for me, and its very simple.
