best squirrel rifle?

[8X56MS]

I use two different .22 LR rifles for Squirrels. When there are still leaves on the trees, and a quick second shot might be needed, I take the Ruger 10/22 with the laminated Mannlicher stock This is a scary accurate rifle.
In late season, its the old Remington 521t Junior Special. With the equally old Weaver K4 scope, its been slaughtering squirrels for at least the 40 years I have owned it, and I got it second hand. With the CCI Stingers that it likes, it will shoot dime sized groups at 50 yards all day long.
