The newest generation of plastic vanes for archery are textured to promote "circular lift". Golf balls are textured to promoted extended driving range and straighter flight. Why would it not follow that a rifle projectile could be textured to minimize drag, promote flatter trajectories and shoot straighter (be less effected by spin drift, etc.)? This same texturing would provide relief on the shank of the bullet to compensate for manufacturing defects in the fabrication of the barrel's bore that is seen in many monolithic solids of the day. Ya see what happens to me in the shower???
