[QUOTE="BryanLitz, post: 241782, member: 7848"] Dave, I understand the anticipation. I submitted those (.338) designs in July, and have been eagerly awaiting their arrival myself. As stated elsewhere on this site, the current projected availability date is summer 2009. The wait is long, but I'm sure that it will be worth it. I for one would rather wait and have it done right rather than hurry up and release bullets made quickly to meet a deadline. When they're available, they'll be right. In the mean time, I can offer the following estimated performance of those bullets: 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). These numbers 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. The BC's are average 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 I hope this will hold the lynch mob off a little while longer! Take care, -Bryan [/QUOTE]
