[QUOTE="Brent, post: 34273, member: 99"] Jeff, Jim didn't indicate it on the site, but he added to the "DROP" from bore line column an "MOA" output option in the latest release version after I bugged him for it so I can figure incline/decline firing solutions more quickly using the Sierra method. I use it to find the average difference in "MOA" between DROP and PATH from about 300-1000 yards. Keeping this number in your head, one can add this to the exact MOA correction in the field if need be and not have to fiddle with calculating what the bore line drop is at what ever range in order to find an accurate number to work in the incline/decline correction formula. All this does for the guy looking for the most accurate method to determine a correction on angled fire shots is eliminate the need to carry an addition drop chart with them that is actual drop from the "extended bore line". Jim made some corrections to the "CANT" calculations too, as Dave and I were breaking code while running numbers on 90 degree cant situations with a near zero. I still haven't looked to see if he was able to completely correct the errors that resulted using a near zero instead of a far zero in combination with such an extreme cant condition. [/QUOTE]
