I'd say marlin will jump in on this new caliber but I'm gonna get one I don't need it but its new and I want it lol
Doubtful, and if they did, the Remington/Cerberus folks would foul it up somehow. Marlin currently has NOTHING that can be altered/converted to the new round. They've not made a Hornet length action, ever, nor a rimfire with locking lugs, which the new round will require. It would require a whole new action/rifle and I just don't see Remington/Marlin making one for the WINCHESTER Short Mag.Change the name, maybe, and they might do it, but they got burned on the 5mm, and probably haven't forgotten that episode.
