Because your 22 limited journal has no markings it is not from Winchester. I haven't found a 22 limited journal which was not exactly the same outside the house dimension as 22lr mag. I can’t envision how a mag, like you explained, could risk be secure when inserted. A photo https://highimpactrounds.com/product/winchester-super-suppressed-300-blk-200-gr-otr-1060-fps-20-rd-box/
