The old Remington 521-T that Dad bought new for $48 in 1948 has never burped and is dead nuts accurate. The Anschutz 141 I got in the '60s, likewise. Two of my boys have had 77/22's (one stainless/boatpaddle, one blue/walnut) since the mid 80's with no problems. My Nylon 66 just keeps chugging them out, but probably not a precision rifle by most standards. My Sako Quad is extremely accurate and has given me no problems beyond the fact that the .22lr barrel has a tight chamber and if you chamber a round (with some ammo) you should be prepared to shoot it.
