I am sure the regular ML barrel isn't designed for the pressures of the smokeless powder
That is why you have to go with a rifle barrel converted to a smokeless ML.
You can call bullberry barrels and order a 45 cal pac-nor barrel and they will put the lug on the barrel and the new forend so when you get it all you have to do is put your new savage breech plug in and you are ready to go. Mine has a 24 inch barrel that shoots lights out.
