Make certain the gauge is seated against the bolt head and the extractor is out of the way.
Every turn on your barrel is .050". A quarter turn or 90* means that you are somewhere over .010" too long, as exactly 90* would be .0125" too long. If you reload the factory setting could work. If you are shooting factory ammo I would expect some issues with light primer strikes at some point. Possibly case head separation. Personally I would pull the sights and headspace it correctly and see what happens.
If it is 270* off that means you may be .037" too long.
If you check headspace and pull the bolt back and the gauge extracts then it has slipped over the extractor.
