I only have a couple, but what I have I really enjoy. First is a Savage Anschutz 164 w/ Gloss Leupold Vari Xii 4-12x40AO. Tight chamber, tight groups, great trigger - this is how .22s should be made.
Next is a CZ 457 17hmr - I also have a Stainless .22lr barrel that is very accurate. Scope on this one has been upgraded to a Matte Leupold Vari Xii 4-14x40AO. This thing is hell on rock chucks!
