[QUOTE="Charles A, post: 21982, member: 231"] This is extremly easy but just in case I'll put it laymen terms. Here's an example You range a target at 1200yds.The slant angle is 30 deg. The cosine facter for 30 deg. is .8660. Take the slope angle, .8660 times it by true range(1200yds) and you get 1039yds this is your slant range.This is how much the bullet will drop because of gravity.But rember your windage data will still be based on 1200yds because the bullet has to travel through 1200yds of air. Any time you can lower your MOA setting your in a gain position. The nice thing about sloped shots is it gives you some leeway on your range estimation, it increases your danger space.It gives you more margin of error for first round hits.
