I like the idea of a plastic tip all copper bullet without the stupid B.C. killing grooves.
The difference in trajectory due to a difference in BC (if any) is probably less than the difference in trajectory allowed by the extra 100fps or so allowed by the friction-reducing grooves.
Haven't seen side-by-side, apples-to-apples comparisons (same bullet, with and without grooves), but it is just as possible that the grooves INCREASE BC as decrease it. There is a reason they dimple golf balls and the hulls of racing sailboats... (And yes, I know things are different at supersonic speeds...)
