The 450 marlin has an extra long belt so it can't be chambered in other belted magnum cases.Several cartridges that are based off of another, older cartridge, use similar to avoid any possible mistakes by a shooter. A good thing, but apparently some aren't done this way for reasons unknown! memtb
But I've often had the thought that a .350 rem mag accidentally chambered in a .257 wby rifle or anything like that and ought to be possible and "fireworky"
