Nomosendero2,
Actually, a lot of recent bullet-company BC's are pretty good. Many weren't for years because of several reasons, most recently because most companies measured velocity at the muzzle and 100 yards, then figured BC. But BC tends to be higher at faster velocities, so those BC's weren't accurate at longer ranges.
Barnes measures BC's with velocities at the muzzle and 300 yards, so they tend to be pretty good--at least over "normal" ranges.
