J Jason280 Sergeant Full Member Minuteman Dec 18, 2005 518 21 GA Apr 8, 2009 #1 Apr 8, 2009 #1 Any ideas on the amount of drop for a .30 cal bullet with BC of .450 traveling at 2600fps? Specifically, what will the drop be (with a 100 yard center) at 200 and 300 yards? Also, will the bullet remain supersonic at 1k yards? Thanks!

Your local atmospheric conditions will matter in figuring it out. Here's a good calculator: http://www.eskimo.com/~jbm/cgi-bin/jbmtraj-5.0.cgi
