I've had a 10/22 Target for about 10 years. Shot it sporadically, from zero rounds/year to several hundred at a time. Probably around 2000 rounds thru it now.
Have been waiting for some kind of actual mechanical issue to require disassembly. So far, just the most basic of brush & wipe down have been needed.
It just keeps getting more accurate the more I shoot it.
With a Tasco high end 12-36x40 scope, bipod from bench, it will eat the X-ring out of a standard 50' Bulls Eye target at a measured 40 yards.
It's the most accurate rifle I have.
