Vit 133 would be a better powder

If no other pressure signs change primers. If that doesn't sort it have the headspacing and firing pin checked, along with your sizing-die settings.
I would also suggest N130 or N133 would be better for 50grainers in the .223
That said, I have seen CCI 400's crater slightly sometimes on the deuce with what I know are mild loads. Not always a cause of excessive pressure IMO. If you are not getting heavier recoil, sticky bolt lift, ejector wipe etc, then it could potentially be fine. Hard to say without being part of the whole process.

I would agree, N120 is probably a little on the fast side. But not so much that I personally would change, till I'd used that pot up, if that was all I had.
As others have said, a tiny amount of cratering is not necessarily an issue. If the primer were flowing noticibly into the figing pin hole, that would be something to take note of.

Load sounds fine.
Wouldn't worry about the cratering. On a Rem 700 you'll get it anyway no matter what primers you use. Hole is too big for the firing pin.
I run 52gr A-Max in mine at 22gr Vit120. It is relatively hot, but not overly so. Still get good brass life.
Watch for the ejector plunger imprinting on the case head (shiney circle) or sticky bolt lift. They are more reliable signs of pressure.
