[QUOTE="Tangent, post: 1688044, member: 110477"] With today's available technology, the G1 coefficient method is out-dated IMO. There are a lot of assumptions that go into this 'method' but my understanding is that it was based on a 0.308 at moderate velocities at moderate density altitude. It does kinda-sorta gets you close for a fair amount of cartridges, but there's just better methods now. Using JBM, Hornday 4DoF, etc., you can back-out your 'wind-number' for your specific rifle/ammo combo and use it for mil-radian, MOA, IPHY, etc. [/QUOTE]
