Ended up running a range that some expert had equipped with 12 Daisy .22s. By summer's end we were down to eight in safe operating order. The rifles came with adjustable stocks,which when someone was missing the first thing they wanted to do was---. One the barrel liner and barrel became loose, one the receiver was cast and had an air pocket, one was the smoothbore configuration (for "mousekeet", .22 cal trap), and---.
Sometime later I purchased a Ruger Mark II "Competition " slabside, and found after 20 rounds it began to hang up and not chamber fully. A trip to Alhmann's in Moristown to get the chamber cleaned up left me with a super .22.
