[QUOTE="Brown Dog, post: 211030, member: 1622"] Well... ....they're expressly not the same. Suggest you re-read the data in Mattj's post. In his post's final example 'cos applied to comeup' gives a 3" error against loadbase "direct incline entry".....the other gives a 15" error. Which of the 'error(s)' do you consider significant? Given the tone of your post, I suspect you will include " 3" @ 1000yds" in your answer. That could lead into a long discussion as to how one assesses the accuracy (or lack of) of a piece of ballistic modelling [eg how do you know exbal is 'right'....(rather ruins things if your '100% accurate comparator' is actually slightly flawed and out by X" itself) and that would lead into discussion of what constitutes 'within (sensible) tolerance' for ballistic modelling at a given distance.]. If you have the ability to attribute 'correct' or 'incorrect' to a 3" elevation difference @ 1000yds between 2 methods of prediction ....I strongly suggest that you go into business in ballistics :) . I'm sorry to say, I simply don't have the energy (or interest) to debate this further. [/QUOTE]
