When it comes to monolithic bullets, it is important to realize that the copper alloys used to make them are considerably less dense than lead. In general a copper alloy monolithic bullet will the the same physical size as a cup and core that is 20-25% heavier. In other words the 120 grain CX monolith is pretty much the same size as a 140 - 150 grain cup and core bullet. For a cartridge like the Grendel, that means that a lot of that bullet is inside the case reducing powder capacity.
