Look at these 2 bullets. Which one do you think has the higher BC?

    This is not a trick question. Just look at the picture and tell me what you think. They both weigh the same and are both the same caliber.

    Left one. Looks longer and looks to have a longer ogive.

    And the answer IS? I am betting the one on the right just because it looks LESS likely to have the higher BC. Come on Michael tell us what bullets you are showing and their respective BCs.

    Speaking of bullets that fool you. The .243 cal 55 gr nosler varmint ballistic tips have a higher BC than the .224 cal 55 gr nosler varmint ballistic tips!

    224 55 gr .267
    243 55 gr .276

    The left one because of its shape.

    Hard to say, the right one seems to have an longer boat tail of a more efficient angle. Got to take some measurements. I took a few very crude measurements, .1 cal difference in boat tail length, about 3° difference in boat tail angle. The right projectile is definitely not inefficient, I can't judge the impact of the difference in nose design though.
    I'd say they are either similar in their respective drag numbers, or the right one has a lower Cd.

    The one on the left has a shorter bearing surface and longer nose and longer overall. The tail appears to be slightly shorter but hard to say. Definitely the one on the left.

    I WOULD say the one on the left because of its VLD shape, however, the bullet on the right appears to have a hybrid ogive, a longer boat tail, and a longer bearing surface... I'll take the road less traveled and go with the bullet on the right.

    Or, this could be a trick question and they both have identical BC's... :D

    I strangely find myself having to agree with Mudrunner. The vld on the left looks better, but I believe the one on the right is a hybrid which we know has a better BC.

    I'm with MudRunner2005 on this.

    Try to make this a poll.

    Since this is a guessing game, I'm guessing the one on the left is .631 and the one on the right is .626.

    The one on the right traveling at 3100 fps will have a higher BC than the one on the left traveling at 1800 fps. :D Sitting on a shelf form factor from shape appears to favor the left. :D So I say both.

    Well it has me perplexed. I would think by looking at them AND knowing they're the same caliber and weight that the left one would be more slippery. That said they're both .30 caliber and both 168 grains and both Berger bullets. The left is the VLD and the right is the classic hunter. Neither are hybrid.

    Now the confusing part. The VLD is advertised at .473 G1 and the classic hunter is advertised at .496 G1.

    I guess I have a lot to learn about bullet design and BC.
