Regardless of whether the chamber is outsized the act of sizing will lower the surface diameter back again to spec. The one time you'll need a difficulty with brass from a gun using an oversized chamber is swelling appropriate at the base/before the extractor groove.
The truncated bullet at left is loaded far too prolonged to the chamber and reveals distinctive rifling engagement marks that prevented chambering. A similar bullet (Middle) at a rather shorter OAL functions great.
