Ballistic Quick Reference Chart Sticky

[usmc51]

I think a ballistic quick reference chart for the popular loadings used in .308 ARs and the most common barrel lengths of 16", 18.5", 20", and 22" would be most useful as a sticky on this part of the forum. We all benefit from the plethora of .223 ballistic charts for our rifles in various loadings, but I have yet to see a good .308 ballistic chart specifically for the AR. If you are a step ahead of me and have already made one, please post it here. Otherwise, I will have to figure out the best format to make one for the community. Thanks.

To get things started, here is my best effort at a chart for one of my favorite loads, the Prvi Partisan 168gr. HPBT at 2608fps and a BC of .480. This is assuming no wind, sea level, 65 degrees, and a sight height of 2.5" above the center of the bore (if you know exactly, please let me know and I'll recalculate).
