The Experiment One of the first things I discovered is that a 26-inch barrel is too long for the .223/5.56. The difficulties of ballistics calculation have to do with data collection, not calculation methods. The general rule of thumb is that one inch of barrel length will change velocity by about 50 f.p.s. Learn how your comment data is processed. These represent my three favorite barrel lengths for an AR-15. I didnt even notice that when I first wrote this up. Ballistic coefficients are measures of a bullet's relative efficiency. And after further investigation, I realized that it was indeed an error in data selection for the charts. Check our handy chart above for a rough guide to this. A bullets velocity is determined by many factors, with barrel length being just one of them. It is not a book for those without a very strong math background.
