Not to downplay your displeasure, but you do realize that just because the bolt closes on a no-go doesn't mean that it is out of spec, right?
The go gauge is minimum SAAMI length, a no-go is usually SAAMI minimum +0.006" (Manson, however some are +0.005"), and the field gauge is minimum +0.010". (

Whose gauges are you using? You could very well have a chamber that is still in spec but 1 or 2 thousandths long from a "general practice" standpoint. It doesn't automatically mean you have excessive headspace, and depending on the chambering and if you plan to use Hornady ammo, having a bit more room in the chamber may be a good thing as I am seeing and reading a lot of people having pressure issues with Hornady ammo in tight chambers.
Just food for thought.
