These little Ruger .22 autos have a pretty good reputation as reliable guns. Mine was--until I tried some WW Xpert .22 LR.
When I would shoot it, it would click on the next round. When I pulled the bolt to cycle it, it would eject a fired case and chamber a fresh round. Then another 'bang' 'click.' Same thing. A fired case was still in the chamber.
It didn't do this 100 percent of the time. Maybe five or six out of a magazine full.
I got to the point that I was watching for an ejected case in my peripheral vision. If I saw one, I knew I could fire again. If I didn't, I had to shuck the bolt again.
I'm guessing that the bolt only went back far enough to partially cock the hammer but not far enough to hit the ejector to eject the empty or strip a fresh round out of the magazine.
Xpert was the only ammo that caused the gun to do this. Xpert worked perfectly in my other .22 semi autos. My solution was to just not use WW Xpert in the Ruger. Never did figure out for sure what caused this.
Anybody else ever seen this happen?
