[QUOTE="Mikecr, post: 220332, member: 1521"] Base drag is definitely higher with RBT bullets due to turbulent flow brought on sooner. But there are both pros/cons to this. Higher base drag improves stability by pulling center of pressure back closer to center of gravity. With this, a bullet with a very long aluminum tipped nose might still be stable where it wouldn't with a standard 9deg boat tail. Higher base drag combines with overall drag to reduce BC. Even with reduced wave drag from a very pointy tip(in this case), BC would still likely end up lower. RBT's might have the potential for better muzzle release. Not as good as flat base, but better than BTs.. I see alot of experimenting here with tips and tails, but I doubt any will produce better bullets than we already have. And the reason I say this; None of it is new.. [/QUOTE]
