In .284 caliber, the 156g Norma Oryx has a listed BC of 0.330 on the MidwayUSA site. In comparison, the 160g Woodleigh bullet has a listed BC of 0.486. They both appear to be protected points bullet and of similar shape, so I was wondering if the listed BC of those bullets are that dissimilar.

Anyone shoot either/both?

How does field data relate to listed BCs?

Thanks in advance.
