How about a new Marlin or Ruger in the new .17 HMR cartridge? It is a .22 magnum necked down to .177 cal. There is an article about it in Feb. SHOOTING TIMES.
Or buy a T/C encore rifle in what ever barrel turns your crank and then when ever you get an urge to buy a new gun, just get an additional replacement barrel for the Encore. Go to (
www.virginvalleyguns.com) and look at the list of standard and wildcat barrels you can get for the Encore.
