Re: Barrel Blanks
They have to be machine but there is no liner involved because they are rough turn from existing 22 barrels. These barrels came from rifles that have been re-barreled. Sometimes there not all the same twist, could be from old barrels or new barrels. It just depends on what he get from the gunsmith. From what he told me is the gunsmith does a lot of .177 cal. conversions.
