[QUOTE="ez bake, post: 912678, member: 229"] I've been playing with ballistics software for a little while now and trying to get some guesstimates together to take a couple of different rounds out to 1000yds and get some real measurements with a couple of newer rounds I'm trying out. I understand most of what I'm reading (or at least I can fake it), but how is trajectory measured? I keep seeing these numbers in my charts and in the software and I have no idea what the heck they mean (I've googled a couple of things, but can't find much that dumbs it down for me). Also, if I've figured my come-up for various distances in MOA, and I try and convert that number to Mils for holdover, it doesn't ever equal the same thing that the software converts it to (I'm assuming this is because I'm using 3.5 as a guess where the software is either using 3.438 or 3.6?). I've now read mathematical answers as to why a Milradian could be either3.44 or 3.6 (rounded) in MOA, but I'm not sure which is the more trusted (so I did what a lot of sites suggested and split the difference to 3.5). This isn't working out very well so far as I have to keep cheating by using my software to double-check what I'm getting in my own math. [/QUOTE]
