In my humble opinion the real magic of the .50BMG is not blowing stuff (or living critters) to tiny pieces (or a red mist). It's the incredibly high B.C. and all that comes with it.
I will have to disagree with this statement to the same extent that I agree. YES there are some BMG rounds out there with high BCs that top 1.0 perhaps even 1.1 and those BCs might be the highest of any readily available bullet on the general market; BUT considering the size of the bore, those #s don't completely impress me.

Correct me if I'm wrong, I am No expert, but in general the bigger the diameter of a perfect sperical ball of the same density the higher its BC will be. If I apply this line of thought to a .510 bore than I think its not that impressive to get the BCs we see in BMG ammo.
I think perhaps the BCs are limited by the maximum practical weight of the bullets.
I will even theorize further to say that IF a cartridge similar to the 416 barret were to have been invented some 90 or so years ago in place of the 50bmg than by this point we would probably have some custom built rifles out there designed to chamber Very long .416 bullets with weights in the mid 4xx grain range and BCs significantly higher than anything we currently see today.

Please don't misunderstand, I am not trying to knock the 50bmg, I'm a fan. I'm just a little tired, a little drunk (sorry) and I felt like having a short rant about how it seems there is a lack of super high BC bullets available for large bore rifles comparted to the very high (for caliber) BCs that we see in the smaller calibers.
