i am building a new scout rifle based on the new marlin 450 cartridge.its essentally the 458 america case with a longer belt.i am going to build it on a winchester controlled round post 64 action with a walther barrel and the ashley foward mount and ashley sights for a backup.this would make it just as handy as the marlin guide gun in a bolt action.if i can build these in a take down rifle would anyone be interested.?its just a concept i had but i think it would go over well.any takers?
