Anyone got any good resources? I know very little about slope doping and my only bit of land requires me to sit in the upstairs deck of a house looking over a down-hill bit of land that goes into a larger hill for a back-stop (I've got 1000 yards of land this way and its the only place aside from Red Castle that I can shoot at this distance).
I've got some steel targets fab'd up thanks to a friend, and while the angle's aren't terrible for the most part, there are hills at the various distances that I plan on putting steel targets and some of the valleys in between these hills are probably down at a 15 degree angle or better.
Since I'm not reloading yet, this ammo is costing me a lot per shot, so I'd like to screw up the least amount possible (especially since I'll probably have a 10 year old spotter who might not be concentrating at the right times to point out where my hits are ending up should I miss them through the scope).
As I understand it, its all just basic Trig (that I thought I could comprehend). I've got wind adjustment down (when I can actually guess it correctly - or even close, but at least I comprehend what I need to do even if I screw it up).
As I understand slope doping, gravity only affects the horizontal distance, so I can perform some right-triangle math given two different elevation differences, but I'm somehow not getting the hang of what my adjustments are after that (using the right-triangle method).
I've read an article by Mike Brown (not the one on this board - at least I don't think) that points out that the cosign method used in my mil-dot masters book is just an approximation for all calibers and ends up several MOA off at greater distances - does this mean that exact measurements aren't necessary or that this method won't work for me after X number of yards?
Do I need to worry about this if the angle is less than 30 degrees if the distances are out to 1000yds?
I can't seem to find a copy of "The Slope Doper" in stock anywhere and I'm striking out with online resources.
