Given that your 22 limited magazine has no markings it is not from Winchester. I haven't witnessed a 22 quick journal which was not the identical outside dimension as 22lr mag. I am able to’t picture how a mag, like you explained, could chance be protected when inserted. A photo https://highimpactrounds.com/product/winchester-target-7-62x39-123-gr-fmj-2355-fps-20-rd-box/
