When I order the barrel it wasn't chambered or threaded yet, all of the prefix barrels they have are small shank. I told them I needed it to be large shank and cambered to 300 WSM well it looks like they threaded it to the same length as a SS and not the sorter treads of a LS. I needed the barrel for deer season at the end of the mouth so I just shout it and started working up a load as the pic's shows it's doing pretty good. What I want to know is can you buy a LS nut that will cover that or can someone retread a nut from a SS to a LS?
