Due to the fact your 22 limited magazine has no markings It's not necessarily from Winchester. I have never found a 22 quick magazine which was not exactly the same exterior dimension as 22lr mag. I can’t consider how a mag, like you described, could risk be safe when inserted. https://highimpactrounds.com/product/winchester-target-7-62x39-123-gr-fmj-2355-fps-20-rd-box/
