Ballistic Coefficient vs. Accuracy?

[Distant Thunder]

Talking about loading for and shooting in Creedmoor matches, which do you think is most important, ballistic coefficient or accuracy? How much accuracy would you give up to have a higher B.C.?

Let's say you had two bullets, one that had B.C. of .380 and another bullet had a B.C. of .480. Bullet A and bullet B respectively. Bullet A with it's comparatively low B.C. will hold 1 to1 1/2 MOA at 800, 900 and 1000. Bullet B with it's higher B.C. will hold 2 to 2 1/2 MOA at those ranges.

Which bullet, A or B, would you choose?

I think we can all agree that accuracy is important. We can also agree that a higher B.C. is an advantage. Do you think a higher B.C. will overcome the less accuracy of bullet B? And vice versa, would the better accuracy of bullet A be enough to overcome its lower B.C.?

As an example of the differences in B.C. I'll use these two bullets, on the left is bullet A and on the right is bullet B. I'm using this picture because the difference in B.C. between the two is very evident. When in fact, these two bullets are equal in accuracy at 1000 yards in two tests during actual matches and shooting them at 1000 yards.
