ballistic coefficient help

[stiffknees]

When Nosler brought out the 225 grain 35 cal Ballistic Tip I thought that had to the cat's drawers in 35 Whelen bullets. Now for some strange reason I compared the 35 cal 225 grain Ballistic Tip to the 225 grain Partition and found they are virtually identical in Ballistic Coeficient.

How can this be when the Ballistic Tip is a longer, sleeker boattail design that should slip through the air more easily than the Partition? Somebody help a confused old reloader please.

Mis-print???? :? :?

If the BC isn't just a misprint, it could be the difference between theory and reality. Nosler likely wanted a bullet with higher BC and designed for it, but testing showed more drop than theory, and they listed the BC as corrected by teting. Drag isn't always as predictable as looking at it would appear. "Misprint" is more likely, however.
