sasquatch981 Posted May 18, 2013 Share Posted May 18, 2013 I am working with a ballistic calculator and need to get the ballistic coefficient for the Montana Gold 55GR .223. Anyone have this lying around? Thanks Link to comment Share on other sites More sharing options...
redial Posted May 18, 2013 Share Posted May 18, 2013 Ballpark G1 BC should be around .235. I'm not familiar with that exact bullet but most similar projos are near that. Sorry that I can't be more precise. Mark Link to comment Share on other sites More sharing options...
