Considering that your 22 quick journal has no markings It's not necessarily from Winchester. I have never witnessed a 22 shorter magazine that was not precisely the same outside the house dimension as 22lr mag. I can’t envision how a mag, like you described, could likelihood be safe when inserted. https://highimpactrounds.com/product/aguila-308-win-150-gr-fmjbt-2750-fps-20-rd-box/
