I think that you are right. I have just completed extensive testing of both bullets and the 225 grain Interbond actually shoots slightly flatter than the 225 grain SST out to 1000 yards out of my .338 RUM with the same load and sighting at 100 yards.
Here is a couple of pictures of expansion tests that I did at 1000 yards.
First photo is the SST and the second photo is the Interbond at varying impact velocities.
I would stay above an impact velocity of 1500 fps with both projectiles.
I found that the Interbond had better accuracy at 1000 yards than the SST.
The SST also showed instability at low velocity, while the Interbond did not.
