[QUOTE="BryanLitz, post: 252161, member: 7848"] Here are the projections as given on a different thread of this forum: All of the Berger .338 bullets are designed to be stable in a 1:10" twist, at any reasonable speed (anything over 2200 fps muzzle velocity). The BC's are based on the dimensions of the bullets, and a database of information I've compiled that relates measured (tested) BC to bullet geometry. This method results in estimates that are typically within +/- 3% of the measured BC. BC's are given as average values from 3000 to 1500 fps. 300 grain Tangent (non-VLD) ogive: estimated G1 BC: 0.749 lb/in^2 estimated G7 BC: 0.384 lb/in^2 300 grain Secant (VLD) ogive: estimated G1 BC: 0.855 lb/in^2 estimated G7 BC: 0.438 lb/in^2 Take care, -Bryan [/QUOTE]
