Surpluses secret project really has me thinking. What about 300wsm? it's about same case only fatter but no bigger then the base of the 54r. Would have to make it a switch barrel setup and that doesn't bother me. http://bulletin.accurateshooter.com/201 ... mpetition/
I say go for it!! A 300wsm is a little step up from the 54r case... external balistically speaking. You shouldn't have any problem finding a load that would be consistent out to 1500 yds.
I'm just throwing this out there... but you could make a dedicated 300wsm and use DBM's.
The savage magazines are double stack/single feed.
I'm sure it would be fairly easy (comparatively) to adapt some bottom metal for the Mosin that would accept the Savage magazine. The design of the magazine would limit the amount of receiver modification. The bottom lug would have to be squared though... like on Dmitry's 8mm.
