have purchased an extra set of barrels for a stevens 311 in 410. one of the barrels had a dent about 8" from the muzzle end and needs to be raised ect. have had several dent removed from 12 ga barrels and have been satisfied with the results. am aware of the metal slug and the screw expander device used inside the barrels to raise the dent and recontour ect. the 410 barrels appear to have thicker metal than say a 12 ga barrel and want to know how well dent removal works when it is used on 410 barrels. anyone out there have any experiences they can share on 410 barrel dent repair?
