[QUOTE="HoLeChit, post: 3527403, member: 35036"] Best bet is to use a chrono. but if you're like me and don't have one, then to estimate you need to figure out what your loss of velocity per inch is with your platform. This can be tricky, as most of these tests are done with bolt guns. But here's what I have found so far. [URL]http://www.sadefensejournal.com/wp/barrel-length-studies-in-5-56mm-nato-weapons/[/URL] [URL]http://www.ballisticsbytheinch.com/223rifle.html[/URL] Then just punch that number into this calculator combined with the info you find on Winchesters website for your selected round. [URL]http://www.shooterscalculator.com/ballistic-trajectory-chart.php[/URL] At 500yds or less with this platform should be pretty easy, I wouldn't stress about it too much, just look these numbers up and then get a feel for it. 3-400yds will come to you naturally. If you want to find manuals for the AR platform, targets, or other goodies, I have a google drive listed here with a wealth of info.
