Is it possible to have a favorite rifle that you never have owned, or even handled? If so, mine is the Winchester model 63.
The only 22 LR semi I do own is a Marlin 60. I have owned a couple of 10/22 versions, but they never hit me hard enough to keep. I had fun shooting them, but not enough to keep them. Maybe a Ruger LVT 10/22- but who knows?
I’ll keep on dreaming about a Winchester model 63.
