I've visited with Hornady several times over the last two years concerning the undesirable SST performance..They have redesigned more than several calibers with heavier jackets and the 139gr is one so they said..Been loading it for a deer hunting friend's 7x57 and my 280,, it behaves well in this velocity window.and should be OK even for the big 7.. I'm always amazed at how Bergers slide by the criticism since witnessing some of their destruction on game as well.
