I wouldn't expect the same load to shoot well after a chop. I subscribe to the OBT method and the goalposts are moved when you shorten the barrel. That's not to say you won't get lucky or find that the old load shoots acceptably.
Recently had my 6.5x47L chopped from 28" to 20". It was sub-MOA before and is definitely still sub-MOA now but the loads are different.
