I'm not sure his "increased surface area = less drag" statement is correct.
I think what's going on is he's altering the air boundary layer over the bullet....if increased surface area equated to less drag then a semi truck would be more aerodynamic than a Ferrari because the semi truck has more surface area than a Ferrari does.
He's utilizing a "golf ball dimple" idea to reduce the boundary layer surface friction... kinda like the crazy swim suits they make for Olympic swimmers or downhill skiers is my guess.
It will be interesting to see how it progresses....will he sell these bullets to the open market or just his class students? How critical are the twist rates? We all know that some factory barrels aren't exact on their twist rates--- seems like an extreemly specialized bullet.
Let's see more! Maybe he has stumbled onto something---- he said he's not a bullet manufacturer though, so if he's modifying someone else's bullet ( like nosler or sierria) there might be some issues with resale .
More options, the better - hope he goes further with this
