123gr ELD Match BC Discrepancy

[SlappyAbbot]

To date I’ve gotten the best BC data and bullet dimensions from Litz’ books or the Applied Ballistics app. If I get serious about shooting a bullet I’ll pay the $3 and buy the Custom Drag Model from them which is a ballistic coefficient based on velocity decay through the transonic boundary verified by live fire.

Thanks for your input, I'll look into that. Sounds similar to what Hornady is advertising in their 4DOF app.
