Whenever I add multiples of the same caliber to my collection, I make it a different variant (So I tell the wife). In .22 I think a semi-auto (fun), a bolt Action (accuracy) and a pump or lever action. They are all different "tools" with different abilities. Hard to beat the 10/22 for a everyday SA. I really like the CZ 452/455 line for accurate well made Bolt Action rifles. Then my favorite pump is a Remington 552 as mentioned above (Look for older used), but a Marlin 39A is also a great Lever Action. I think owning a rifle that can shoot shorts,longs and LR and also not have a detachable magazine is a big plus. So decide what is "next" on your needs list and remember you can never have too many 22 rifles.
