[QUOTE="kilmer, post: 605839, member: 41193"] How about that? I assumed that because my ballistics calculators and the EL Range pretty closely agreed that they were both using a cosine correction formula to adjust the range. After having spent the last hour playing with calculators, I must say that I stand corrected. There is obviously something more at work here than a simple cosine calculation. When I input a 30 degree angle at 800 yards I get anywhere from 715 yards to 765 yards corrected distance depending on caliber and calculator. Straight cosine would yeild 692 yards. There must be some sort of statistically averaged ballistic profile that they use for calculation. I'm going to find out. I stand firmly by everything else I posted, unless NZ Longranger says otherwise. :D [/QUOTE]
