I guess it would depend on your type of shooting, it probably wouldnt hold me back. The higher the BC the flatter the bullet will shoot is my understanding. It isn't a big deal to me cause I don't really shoot long range often now, i plan to eventually but for now I'm just hunting so it's usually 500 and in for me. I bought a bunch of different hammer bullets for multiple calibers even tho I knew the bc would probably be incorrect and will continue to tinker with them, especially in 6.5 PRC and 375 raptor. I just think the drama about their BC is kinda funnyI know that BC is a metric of air resistance, a bigger number is better. Does BC affect precision or just drops? Ive never got the advertised ballistics or velocity from any brand of ammo or bullet. Hammers are precise enough, if someone is getting 1moa or better how does a lower BC hold them back?
