Buy another Ultra, like the 308 or 25-06 and send in the frame for a 22 Hornet barrel. Sure you would have to switch barrels, but only twice a year. Put on your deer barrel in September and check your zero, shoot your deer in November and switch it back to 22 Hornet until the following September again. While you have it in getting the 22 Hornet barrel, order an extra fore end so each barrel has a dedicated fore end. I have two frames and 6 barrels. Both frames have Cinnamon Lams and each barrel has a dedicated Cinnamon laminated fore end so each is an Ultra, per say. I started with a 223 Ultra Varmint, added a 357 barrel (reamed to 357 Max) and a 30-30 barrel. Then bought a 44 Magnum and then added a 22 Hornet (stubbed to 22K Hornet) and 444 Marlin barrels. I now have every thing covered from small varmints to the biggest four legged critters in North America with a Handi.
Good Luck and Good Shooting
