BIL, you are, what I call, "geeking out" over the small stuff trying to figure out what bc is best. If you want a lighter bullet going fast, bc shouldn't be apart of the equation. There's 3 options- light bullet (55-70 grains) going 3500ish fps, medium weight (80-90 grains) going fast 3200ish fps, and heavy (100-115) still going fast 3050-3150 fps. The lighter the bullet, the lower the BC, and the heavier the bullet the higher the BC. Everything is a compromise in shooting. You have to figure out what you are willing to compromise. If you want to shoot the longer ranges, you can balance your bc with speed and pick the middle weights, like an 87 grain hunting VLD. I have numerous customers running this bullet at 3200 fps with great success long range plinking and on game. If you want faster, then go lighter with the lower bc. If it's for predators, I'd go lighter and run a 55 or 70 grain Nosler BT, or if you want less expansion, get a 60+ grain Berger target bullet that the jacket holds together well for less fragmentation.
