Max Heat

Being that I am one of those folk who has that pesky "need for speed", I (almost exclusively) run nosler 120gr ballistic tip 7mm rounds, out of a rem mag, and will be stepping up to ultra mag, when my new barrel arrives. In terms of heat, that will put me into a new league. But it is going to be really hard on the barrel's throat, and I am trying to think of methods to maximize it's useful life, as I don't plan on shooting light loads, after the barrel is broken in.
I am debating whether or not to start moly coating my bullets, as that is supposed to help extend barrel life. But is it really a worthwhile endeavor? Also, lyman states that the moly-coated bullets will result in lower pressures being generated, which I look at as a GOOD thing. But perplexingly, they state that velocity will also be lower with moly coating. It doesn't make sense to me that a bullet that generates less friction going down the barrel will have LOWER velocity. Is it possible that it is a mis-print? If not, could someone please explain to me why that would be?
