Well, they're .18" smaller. That's a huge difference when you're designing things with tight tolerances. If you'd need a new breech size, new barrel size, and a new feedneck size, it'd only make sense that you'd need a new hopper size. If you have a gravity fed hopper, it MIGHT work given you modify an insert for the feedneck of the hopper... but then again, the companies manufacturing these markers are making smaller feednecks on their markers to incorporate the entirety of smaller markers, so it'd only stand to reason that a standard .68 cal loader would be too large.
