Anyone ever removed a rifled barrel from their shotgun after sighting in at the range and then replace it and recheck the gun's accuracy?

I have a scoped 870 express combo. sighted in for deer season next Monday. However, I may do some hunting a day ot two prior which would require removing the rifled barrel and using the smoothbore barrel.

I don't have the time this week to recheck accuracy at the range after removing and replacing the rifled barrel.
