My very first .22 lr was a Ruger 10-22 Bicentennial which is still running strong today after countless 1000's of rounds,
picked up a second one as a backup as well as a SS version that I unfortunately traded away .

As for bolt actions while my buddy swears his CZ is great Im a died in the wool Ruger rifle fan and so decided to try the Ruger 77-22 (sort of a miniaturized Mauser 98 action) and was a bit surprised nobody had mentioned one above until I went to Rugers website and saw the $979 MSRP.
Ruger® 77-Series 77/22® Bolt-Action Rifle Model 7002


On a side note it will interchange magazines with the 10-22 as well.
