Hi, mundumugu:
   Just leave it set to G1 for ordinary bullets. That's good enough out past 400 yards/meters. It's a complex function, but if you want, I'll go into more detail later.

  Just one point now. A bullet with a ballistic coefficient of .4 when using the G1 function can have a very different ballistic coefficient with another (G5,G6,G7, etc.) It could be .2 or .8.

Bye
Jack

thank you, Jack. you and all the other americans there have all my sympathy and solidarity for this most absolutely stupid, more than brutal, horrendous, coward, mass-murderous act of evil terrorism that happened in your country. positively, all human beeings were NOT  created equals. May God bless you all.

To mundumugu and the Forum:
  I am Canadian, but I too wish to extend my sympathies to my American neighbours on this terrible day.

Sincerely
Jack Monteith
