[QUOTE="Michael Eichele, post: 480377, member: 1007"] Welcome to the site. :) There are many factors that will come into play as to why one manufacture publishes a value and another manufacturer posts another for a very similar design. One may test them at 100 yards where the other tests them at 200 yards, small differences is design (it does not take much design difference to make a 3-5% difference). There are often times differences between manufacturer's testing systems etc..... That said, the difference between the IB and the BT is about 5%. Like you said, at the ranges you are talking, 5% does not matter much. Factory published BC's are more of a better place to start than an absolute anyway. If you really want to open the can of BC worms: [url]http://www.longrangehunting.com/forums/f19/lets-argue-about-bcs-68234/[/url] That will keep you up all night once or twice. Good luck! M [/QUOTE]
