There have not been many good 22 semies made.
The best ones I have owned are
1. Ruger 10/22
2. rem 552
I would like to try a cz 511, a browning 22 auto, browning buck mark rifle, a TC 55 (baisically a copy of the cz 511) If you dont want a 10/22 because everyone else has one try to find an old 10/22 international they were a beautiful little rifle and there's not many around. Oh and the only plastic on my ruger is parts of the mag. if you want a semi that is all steel as in no aluminium alloys or plastic, I think the browning 22 auto, tc55, or cz 511 are your only options.
