Would this need be filled by the .338 Marlin? That's shooting a 200 grain bullet at well over 2500 fps. I suspect you could slow it down to 2200 with entirely safe pressure if that was the goal.
Of course, you only get one factory load, no component brass and from what I can see no other component bullets, but then I haven't really looked.
But on the bright side it's an excuse to buy another Marlin levergun.
