[QUOTE="Long Time Long Ranger, post: 374182, member: 505"] Just looking at it I thought the bc would be higher. I don't think the bands would have much effect on it. In missile work I was involved in flow field dynamics some simulating turbulence over the nose cone of a missile and photographing it. High speed photography showed the turbulence flow field was well beyond the side of the missile and with a bullet I would assume well out beyond the bands or canelure of bullets. In other words the turbulence created by the point of the bullet as it slices through the air is directed away from the side of the bullet depending on the angle of the point. This leaves a little void where the bands would be without as much air flow over it so the resistance of the bands should be minimal. I wish I could explain that better without writing a thesis. May or may not be true with bullets anyway but I would assume the same principles would apply. [/QUOTE]
