Stefan,<br><br>New England Firearms makes a rifle they call the "Survivor." This is a single shot, break-open rifle chambered in either .223 or .308. While I don't own one, I have shot the one my buddy owns (a .308) on several occasions. Nice rifle, very accurate. The trigger isn't bad, isn't good. With practice, reloading is pretty quick (it has an ejector, the one on my buddies is powerful, a freshly fired .308 case bouncing off the forehead is not fun, so be carefull.)<br><br> I used to own a .32ACP chamber adaptor for my single shot .30-30. It worked fine and was fairly accurate. Little thing, easy to lose, though (which is why I USED to own one.) Someone still makes them. If you insist on being able to shot .22LR's through your gun, you'd probably be better off with a .223. <br><br>Positive bouancy aftermarket synthetic stocks are available if you look hard enough. Not cheaply, though.<br><br>Andy
