hard to find but a geco mauser in 10,75x57 seems to be the right thing

458 lott case is to long, the 450 Marlin is just the right thing. metric it would be a 11,6x53 and ballistik is very similar because the marlin made 640 m/sec with a 350 grains bullet and the old 10,75x57 made 620 m/sec with a 350 grains bullet.
