Given that your 22 limited magazine has no markings It isn't from Winchester. I have never seen a 22 shorter journal that was not the same outside the house dimension as 22lr mag. I am able to’t envision how a mag, like you explained, could risk be protected when inserted. https://highimpactrounds.com/product/winchester-super-x-308-win-180-gr-pp-2620-fps-20-rd-box/
