? about BC of bullets

[barthowes]

So I did find the 200 gr 358 accubonds on Noslers site when you scroll down through the chart. But i later noticed something odd. they say the 358. 225gr AccuBond has a BC of .421 and the 225 Partition has a BC of .430. that has to be a misprint right.

Reloading Guide #7 shows the those BC's to be backward--AccuBond: .430 and Partition: .421

 

[JD338]

The .358 200 gr AB BC is .365, the 225 gr AB BC is .421.

The Partition and AccuBond are very differently shaped bullets. The AccuBond is a boatail bullet and has a longer profile than the Partition. The Partition is flat based and has a shorter ogive radius by inspection. I would expect them to have different Ballistic Coefficients. Compare them by placing them next to each other. The AccuBond is somewhat longer than the Partition bullet.

AB is quite longer and has a boat tail. that is exactly why i could not understand how the Partition has a higher BC. something has to be wrong with the partitions BC since JD338 just confirmed the BC of the AccuBond.

It most likely is a misprint.
