[QUOTE="Shawn Carlock, post: 196157, member: 4"] 30-338 Your on the right track. cos x dope for uncorrected distance has less margin of error than the cos x distance then getting the dope for corrected distance. Neither one is correct, they are better than nothing and either will work if the distance is a. close or b. a slight angle however after much field testing with multiple rifle the Exbal program wins hands down with cos x dope for uncorrected distance running a distant second. My whole point the up/downhill corrections was to carry a drop sheet generated by an accurate ballistics program because applying the cosine is not as accurate for long distances and / or steep angles. The NF Exbal program takes into account several factors to get the right dope and direct application of cos. does not, like the time of flight staying the same despite the gravity distance changing, angle of departure blah, blah, blah. So at big distance application of cos just is not accurate enough for me. Sorry if that did not come across clear enough. If you have any other questions drop me a line. [/QUOTE]
