I have two Marlin 39, one from the 1920s and one from 1987. They are both great shooters.

Another one is the Winchester 63. It was my dads rifle and it is a wonderful shooter.

Also, as mentioned, the Browning T-Bolt, not the modern day one. It's an amazing shooter.

The last one to mention is the Browning 22SA, which mentioned before is still being made today.

All are great rifles and would be hard for me to choose just one. Also, all but the T-Bolt are take down models as well, if that appeals to you at all.
