I just looked them up on their web page. But their lighter ? How is that going to translate into higher BC ? Look Nosler has a 55gr Boat tail bullet with plastic tipped bullet and its BC is lower ? Besides how much difference is .40 BC going to make ? A while back I connected with a coyote at nearly 300yds with 55gr V-Max out of a AR-15. I hardly had to apply much hold over in High desert thin air.I'm not going to lose any sleep over this.
