[QUOTE="Brent, post: 14784, member: 99"] I have several drag curves if you recommend one? I can also enter multible BC's (5 seperate ones) at multiple VE ranges (5 also). By the way, I'm getting a BC of .524 with the 180 Nosler BT and .576 with the 180 Scirocco at 3200 fps on the Oehler 43 both are at 63,000 psi. 96.5 and 97gr loads were at 70k psi and MV was 3347, how would I get 3400 with the same powder just changing primers, is it possible you think? I shot the 180 BT at 600 yards, it took 9.75 MOA to zero it. The results with a MV 3400 and BC .520 are... 100= -8.5 200= -7.6 300= -6.0 400= -4.2 500= -2.2 600= 0.0 700= +2.5 800= +5.2 900= +8.2 1000= +11.6 Are we looking for the 100 yard numbers to fall on the tics?
