Buy a nice 22 bolt gun, a nice 22 target pistol, keep your CZ and a carry gun. Now that I have a suppressor on my 22 rifle it's almost all I want to shoot and it's cheap. When you retire I'm sure your network of shooting friends can help scratch your itch when it comes to trying out new guns rather than buying and selling. You can also get a membership with a nice range or conservation club so you don't have to pay range fees all the time.
