[QUOTE="Michael Eichele, post: 277958, member: 1007"] On the Lilja website you can download an excel file for twist and BC. You can enter many key measurments of a given bullet and it will give you an approximate BC. Close enough to get you on paper. As a side note, even bullets that have a published BC attached to them need to be tested. It will vary from rifle to rifle and from velocity to velocity. Most if the time published or calculated will get you on paper so you can fine tune the number yourself. [/QUOTE]
