Again, super slow this time: conversations of 500 yard data cannot be founded on 200 yard shots. We can go into turrets and atmospherics and what impact zeroing at 70 degrees has when taking a shot at 20 degrees - but none of that matters. Unless I missed it, we are discussing a 500 yard shot in terms of 200 yard shots. It's kinda like saying you really good at fucking because you are really good at jacking off.
Anything at range based on a ballistics calculator is terrible, terrible planning and executing.
I reread the original post to be sure I didn't miss it, and yup, no mention of measuring anything: no chrono, no 500 yard data, nada. Maybe it happened but was excluded from the post, don't know, can't help solve a problem with zero real-world data. Hell, even the 200 yard shot with expectations of a 32 inch drop (though off) doesn't have a data point.
I'll leave this now, given that I cannot help. I usually try to help.
Usually.
