Just got the new Harrington+ Richardson, New England Firearms catalog yesterday, and they do have the single shot breakdown rifles chambered in this caliber. Heavy barrel with scope mount rail included, no iron sights. It will probably be the most economical rifle you can purchase in this caliber. Marlin Firearms Company bought them out in 2000. With their capital behind them, i would surmise that there will be more products coming in the future.
