Is there a SAAMI standard that specifies a "norm" or a "range" for the bolt face to lands measurements for any giving caliber?

Is there a name for that measurement?

Is it common practice for bullets to be placed in the lands?

Now that I am armed with this info, I have been able to go back and measure factory ammo I have tried in the past. Some of the product that didn't work well in my rifle seem to have the bullet setting in the lands. I had wrote it off as bullets my rifle didn't like. Other ammo that worked better weren't quite to the lands. Turns out it could be a depth issue.
