Would the 8 mm Maximum boolet at .325" as cast diameter be a total failure in a .338 Win. barrel (.3305" lands / .3382" grooves) if paper patched to groove diameter plus .001" ? This is Oldfeller's design for worn throated Mausers and it weighs in at 244 grains unchecked. Figured I'd ask before proceeding with rebarreling a .375 to .338 to use as a cast boolet rifle.
