Actually it is the barnes manual that underloads the 7mmremmag.

From the nosler fourth edition-7mmremmag using h-870
160gr bullet -3112fps
Which is faster than the barnes 30-06 load that you keep referring to.

So if you insist on using the highest velocity that either of us can find in a loading manual,the 7mmremmag does win.

Now keeping in mind that the barnes xlc loads use coated bullets that doallow for more velocity than uncoated bullets,the barnes data for the 7mmremmag is even more pathetically mild.
In fact the 160gr loads for the 7mmremmag exceeded 3000fps in the nosler fourth edition,hornady third edition,hodgdons 26th edition,speer reloading manual#9,sierra bullets second edition and lyman 45th edition.And in all of these manuals,uncoated bullets were used.If the barnes data is so good why couldn't they exceed 3000fps with a coated bullet when everyone else did it with an uncoated bullet?In all six manuals that I listed the 160gr loads for the 160gr bullet exceeded the 165gr loads for the 30-06.In most cases the difference was in excess of 100fps.That makes it six manuals against the lone barnes manual.Would you rather doubt six manuals or one?I think that it is the barnes manual that should be used for a doorstop.
