no horror stories from my neck of the woods.
Even the skinny barreled models can be accurate if you use heavier bullets. I remember having a stainless 180 +series that I got consistent 1 and a half inch groups when using 69 grain match factory loaded ammunition. 2 and a half inch groups using 62 grain ball.
6 inch groups using 55 grain ball.
That skinny barrel did a poor job of taking out bad harmonics and the twist rate was very high for lighter bullets.
Reliablity wise I think they have all ran like a champ. You can run a mini 14 without maintenance for a very long time.
Only problem was a failure by Ruger at the time to provide high capacity magazines to civilians. So you had to get a Ramline hybrid mag if you wanted solid reliablity.
