That would probably increase the amount of blow back and gas cutting - reaching back into the threads of the BP... plus I have yet to figure out why anyone would consistently shoot a loose breech plug... There is a possibility of putting a lot of undue pressure on the threads of the BP and/or barrel threads... drive them forward a bit with the hammer then drive them back with explosion of the the charge... this will wear on the gun over a period of time...
