[ARCHIVED THREAD] - XM855 trajectory

Posted: 12/9/2006 7:01:22 PM EDT

I tried the search and good old google but to no avail. I am looking for a graph of the trajectory of XM855 out of a 16" barrel.
If I had the BC of the bullet, and velocity I could plug it into the JBM calculator and get pretty close. Thanks in advance

I've chronographed IMI M855 at 2984 fps from a 16" Colt barrel. The listed BC is .304.
