Due to the fact your 22 quick journal has no markings It's not from Winchester. I haven't observed a 22 short magazine which was not the identical outside the house dimension as 22lr mag. I'm able to’t visualize how a mag, like you explained, could chance be protected when inserted. https://highimpactrounds.com/product/winchester-defender-12-ga-2-75in-1-oz-rifled-slug-00-buck-1150-fps-10-rd-box/
