You will be pleased to learn that I took my 1970s Ruger 10/22 to the range today -after it had ~ a 30 year rest. Needed to sight the Bushnell "Sportview" 4x scope in again; it got bumped somewhere during the two cross-country moves it suffered. Both the factory 10 round mag and the Ram-Line 25 rounder fed without a hitch (Federal bulk copper plated ammo. That Ram-line is all-plastic (no metal 'lips'), but it shows no sign of wear, so must be I didn't use it much. Another sunny day, temp around 80, humidity around 50%. Summers in Vermont are a trial.
