Twist rate questions???

I have always built with twist rates that calculate out to at least 1.5 on the heaviest/longest bullet I intend to shoot. My best shooting rifle ever is around 1.75. I have recently heard that 1.2 to 1.3 is more ideal. Do those bullets remain stable at 1000 yards? 1200 Yards? Do they de stabilize when the velocity drops low enough to bring the calculation down to say .9 or .8 etc?

I am wondering because I am considering trying some slower twist barrels.
