Out to the 500 yards I ever shoot to I don't think BC is a significant factor. The excellent value 160 7mm Fusions BC is .440 and that's good enough middle of the road for me. Same with the BTs'. A 150 Nosler BT 7mm is .493 which is way better than the Fusions. And the 150 Nosler can be sent off pretty quick which is a catch up on the lack of BC. I just dial in the correction which is only a tiny bit more because of the so called "low" bc.
Same with wind.
Its only if I was consistently shooting over 500 yards would I worry about the difference between .440 and .590/.600
Mind you, I'm only speaking from my own world of personal experience so that's a limiting factor in itself.
