Gofast,
Sounds like you've got a tight chamber - tighter than the industry standard SAAMI.
This gives you the option to complain and get a replacement. Given it is grouping 3-4MOA I would suggest you do (regardless that the groups might not be the barrel's fault).
The other thing to consider is safety. As long as whatever ammo you cycle through it is less than SAAMI then you are fine. The lugs will go fully into battery and everything is safe. In fact the brass will thank you for it because the stretch will be minimal on first firing. BUT, if you ever load ammo that is exactly SAAMI (unlikely) then it will be like loading the GO gauge with the bolt only partially closed. Then, as long as the gun cannot fire with the lugs partially closed, again, that is fine. The safe way to test all this is to load that GO gauge and see if you can fire the action. If it won't fire - all good.
Factory ammo is almost always less than SAAMI, so it can be fired from any chamber right up to those exactly machined at SAAMI. Your chamber is less than SAAMI, but as long as the ammo is always shorter than SAAMI and the bolt closes fully (and any hand-load is within safe pressures) you are fine.
Once you have spent cases from that action you can bump them .003" like we all do and it will close properly and fire properly. If you want to keep that barrel then you can even weigh the water capacity of spent cases to know how much less than normal it is. Case capacity affects pressure and if you ever load on the raggedy edge using other people's recipes then be aware their larger case capacities will be more forgiving - you need to be more careful here.
I'd send it back for a replacement, to be safe and sure.
