Ok,

Here's what my Exbal says

500 yards - 2522fps, 2542 ftlbs of energy 35" of drop
750 yards - 2215fps, 1961 ftlbs of energy, 99.5" of drop (I've gained 2ft of drop from the BC on this bullet!) My 160 gr load is at 10' of drop @ 750
1000 yards - 1932fps, 1491 ftlbs of energy, 208" of drop (I've gained 80" of drop and 901 ftlbs of energy!!!)

Def. worth changing bullets if I can get them to shoot. Geesh, didn't know I'd gain so much by 20 grains and almost double the BC. This is with a straight .684 BC, which you know will change at different velocities. Berger does not post these on the website, so the only way you know the true BC at these velocities are actually shooting and checking your clicks. I've always found that they are a bit more than whats listed.

For instance to show you the change in BC, My 160 gr Seirra's go from .384 at 3200 to 2800 fps to .394 at velocities 2800 to 1800 fps, .404 @ 1800 fps and below. That's where shooting them in the field helps determine your actual elevation needed. My Exbal gets you close, but shooting these distances helps you determine the actual clicks and true BC of the bullet.
