[QUOTE="Brown Dog, post: 109794, member: 1622"] earlier I said [ QUOTE ] interestingly, on your linked program, setting zero distance as 1000, cant 10 deg and ticking 'el corrn for zero range' 'az corrn for zero range' and 'drop and windage rel to tgt' .....the windage value it gives is 57" !! (same as my 'clockwork' calculation on your data earlier [/ QUOTE ] but you say: [ QUOTE ] if your cant formula gives me 57" of windage error in the line of sight coordinate system, that doesn't mean that I'm going to miss the TARGET by 57". It's actually less at the target.
