The .338 does have a higher BC, but a great deal of that BC comes from mass (300 vs 195 grains).
The .338 cal 300 grain hybrid has a G7 form factor of 0.895, which is extremely low drag. The estimated form factor of 0.850 for the 195 grain 7mm is about 5% lower drag than the .338 bullet.
When talking about 'slick' shapes, and low drag, it's a discussion about form factor. BC is the combination of form factor and sectional density.
For more background info on form factor, refer to this web-log article:

Please keep in mind this performance is estimated
at this point. Estimations are usually accurate to within +/-4 or 5%. We won't know the exact form factor and BC of this bullet till it's actually made and tested.
