Great thread. I used excel to create a graph showing the relationship of poi relationship relative to a 4moa reddot, which I've found helpful using that sight at distance as a makeshift bdc.

Mine is using a 100yd zero and 60gr tap, so it's not directly applicable, but some may find it beneficial to do the same with bbl lengths and ammo discussed here. If you would be interested, someone can pm me the ballistic data for a specific ammo/bbl combo and I could mock one up and add it to the thread.
