Due to the fact your 22 quick journal has no markings It's not from Winchester. I haven't noticed a 22 small journal that was not the exact same outside dimension as 22lr mag. I'm able to’t consider how a mag, such as you described, could probability be protected when inserted. https://highimpactrounds.com/product/winchester-m193-5-56-nato-55-gr-fmj-3180-fps-200-rd-box/
