Might as well put in my 2 cents worth...
Win 52 Sporter (Pre A)
Win 75 Sporter
Win 69A/72A
Browning Semi-Auto Belgian wheel sight, 22 LR and 22 Short
S&W K-22
Colt Woodsman Match Target 4" & 6"

I think every 22 enthusiast should shoot a Winchester 52 Sporter at least once...100 rounds.

A lot of great 22s listed in all these posts!
