    Range Report Ballistic Coefficients

    Hey guys, Anyone kno where to get a list of ballistic coefficients and muzzel velocities? For .308 I'm shooting out of a 26" barrel and for 5.56 a 10.5" To more specific I'm looking to update some ballistic software and I would like to get the following. .308 Black Hills 175gr. Corbnon 175gr...
