Nothing new there, they were used for magnums when they were plentiful and cheap. The 1917/P-14 are some of the most difficult military actions to sporterize. They've got big, ugly ears that mount/protect the rear sight,,,,, those'll have to go. The bottom metal has a 'dog leg' that needs to go, too. Most are harder than the 'hubs' and can present a real challenge to drill and tap for scope mounts, you'll need $25 carbide drill. And, to top it off, they cock on closing. Those made at the Eddystone plant are said to have questionable heat treat. Those in good condition today are too valuable to cut up.
