|
Hello all, i am looking for a ballistic calculator that will enable me to calculate the different point of impact for my load at slope or angle. The only thing i have found so far show that for 15 degree slope multiply bullet drop by .034, for 30 degree slope multiply by .134 and for 45 degree slope multiply by ..23? Does anyone have or know of anything that actually calculates how much high point of impact would be in a software program?
Thanks,
Toddco

I do not have it with me at work but my Mildot master slide rule does a pretty good job on this too.

Try this site for a look at the Silhouette Ballistics program which allows you to change almost every "constant" item in the process of shooting.

When shooting up or down at an angle the only important factor is the horizontal distance to the target. For example; If the target is 200 yards away but 30 degrees above (or below) you the horizontal component is 173 yards (200 x cosine of 30 = 173). Hold for 173 yards. Its easy to make an Excel file to give you a table for this.
Some of the newer laser range finders will figure this info for you. Leupold calls it "True Ballistic Range".
