[QUOTE="AZShooter, post: 468965, member: 5219"] I use JBM's program. If you have Litz's book you will see he gives lower G1 and G7 BCs for Nosler's accubond/ballistic tips bullets. I did some calculations and came out with a .273 G7 for the 200 gr Accubond. I shot for groups at 300 M and 500 M and the comeups matched. It would be a good starting point for you. Try that BC value and then make adjustments for your rifle. I would suggest you use your chronograph during your testing. Some velocity loss or gain will change your comeups and will have you stratching your head IF you are using the wrong velocity input for your program. [/QUOTE]
